D. schwackei again in flower

[Daniel O.]

Hi Fernando,

i´ve meant rippled leafes.

All other location forms of D. ascendens i´m growing have more planar leafes.

Here a few older pictures with 3 location forms. 2 forms with more planar leafes and 1 form with more rippled leafes.

I hope this explanation is now better understandable.

http://www.cpukforum.com/forum/index.php?s...mp;hl=ascendens

Like i´ve mentioned before, the other parent is D. schwackei. Last year i took the pollen of the last D. schwackei flower (which i´ve pollinated with pollen of D. tomentosa) to pollinate D. ascendens ´Pico da Bandeira, Parque Nacional do Caparaó, Espírito Santo, Brazil´, so it should be D. ascendens x schwackei.

Best regards,

Dani

Hey Dani,

Thanks for the explanations! I see what you mean about the leaves of D.ascendens, how they are not flat in the Pico da Bandeira form. As for the hybrid, it's a real beauty! I hadn't understood that this was already the result of your D.ascendens X D.schwackei cross -- how old are the plants??

Best wishes,

Fernando

P.S. What other hybrids have you made using S.American Drosera as at least one of the parents??

[Daniel O.]

Fernando, thanks for your kind words about the hybrid, i like it also very much.

They are really very fast growers, i´ve sown them at the biginning of February, so they are only about 8 months old.

But somehow it´s a little bit strange, the pollen of D. schwackei seems to work, the stigmas of D. schwackei seem to work (the small green hybrid), but selfing D. schwackei has not worked last year for any reason.

I´ve tried a lot of crossings, crossings between south american species, crossings between african species and in combination of both. Often i´ve also tried the reciprocal crossing to see if both crossings will look similar. But most of them seem to be not so fast growers like D. ascendens x schwackei.

All in all i´ve used these species for crossings:

D. ascendens, camporupestris, graomogolensis, tomentosa var. tomentosa, tomentosa var. glabrata

D. collinsiae, "capensis var. alba", capensis ´all red´, madagascariensis

D. neocaledonica, spatulata var. gympiensis

Perhaps i´ve also forgotten to mention a few.

For a few of them i´m waiting for germination and a few of them seem not to have worked (no or almost no seed), and as i´ve already mentioned a lot of them are really slow growers till now. D. camporupestris crossings have been without any success till now.

Best regards,

Dani

Hello,

Sorry that I did not get into this discussion earlier (but in contrast to Daniel, I somehow never manage to get free of all work for a certain time ;) Dani, what's your secret, haha?).

First of all, I can only second Thomas' and Daniel's obervations: I did not a single seed grain from this "old clone" of D. schwackei (which I, like Daniel, got from Kamil Pasek of bestcarnivourosplants, who grows it from tissue culture). This D. schwackei and the D. "yutajensis" from Duida (from tissue culture of Joachim Nerz) are the only (!) two South American Drosera in my collection that never produced any seed from selfing, nor when I used them as pollen donors for crossing experiments! Problems in pollen meiosis are known after hormone treatment of plants, likewise are infertile triploid plants.

BUT I did easily get viable seed from selfed flowers of a seed-grown D. schwackei from Cipó this season (that's the seed you have sent to me a few years ago Fernando!). Thus I assume that the plants originating from Thomas Carow's collection somehow are a sterile clone, due to whatever reason.

Dani, did you get any viable seed using your D. schwackei as a pollen donor, or only when using this as the pollen accepting plant?

Second: Drosera-hybrids involving a South American species as one parent at least:

Fernando, I made many hybrids with many Drosera species across the world, but did not grow all of them to maturity (due to limited space in my greenhouse). I just tested if the seed was viable, and then usually gave away the plants to friend growers. That's why I cannot show photographs of most hybrids.

Venezuelan species (such as D. hirticalyx, D. roraimae) readily hybridize with many Drosera species if artificially cross-pollinated in cultivation. I made the experience that any Drosera with filiform stigmatic tips is much easier to hybridise in cultivation, than those with a special knob or feather like stigmatic apex. Makes sense to me, as those specialised tips are usually found only in regions with great Drosera diversity (eg. Western Australia, Western Cape, Brazil). Thus in my opinion, this is an adaptation to avoid hybridisation when many different species are growing sympatrically.

BUT you can avoid this reproductive borders when cutting the very tip of the stigmas, and then putting the pollen onto the surface of the cut. Just take care that you are still using some part of the receptive stigma tissue (which is usually white or translucent in Brazilian Drosera species, whereas the style tissue itself is pinkish). This is the only way I was able to create hybrids using species such as D. graminifolia or D. chrysolepis as the pollen accepting plants, for example. Dani, you might try this in order to get hybrid seed from D. camporupestris as well!

Dani, I would be very interested in what species combinations you have successfully created viable hybrid seed.

Fernando, I will readily send you my spreadsheet with all combinations and results I tried over the years (in case I did not do so yet! ;)). I just don't want to make this public here, but publish results some printed journal first (sorry, you may perhaps call this "airs and graces of a fuzzy scientist", haha ;) But at least this was hard and time consuming work ;)).

Third: Dani, I'm not sure if your cross between D. schwackei and D. ascendens was indeed a successfull one. At least the resulting putative hybrid on your photograph looks more like "common" D. ascendens to me. I have observed this kind of undulate leaves in several location forms of D. ascendesn so far, at least when they are in full growth (for example very obvious in the plants that Stefan Ippenberger distributed as D. ascendens originating from "Bandeira Peak" (and as "D. villosa" in the very beginning). But see discussion about the identity and origin of this plant in this forum, some years ago).

All the best,

Andreas

Hi Andreas,

because of my phd thesis i´ve learned somehow to sleep only for a few hours a day , so i´ve always have had a little bit time for discussions.

So we have another one that is not producing viable seed. For my sadness i know this problem also from D. yutajensis (spec. Duida), but also from this "D. esmeraldae" ´Cerro Duida´ (the false one).

So, you mean that this clone of D. schwackei is not producing "well working" pollen because of hormone treatment. Have i understood you correctly?

Good to hear that there are excisting "normal plants" (seedgrown) that are not behaving this way. In this case i´ve to search for seed or seed grown plants.

Many thanks for your hint how to try it again with D. camporupestris, of course i´ll try your method next time.

What do you think about the first small plantlett (the greenish one). Is it looking like a hybrid between D. schwackei and D. tomentosa var. tomentosa?

After selfing D. schwackei has not worked these plants should be "real" hybrids.

Andreas, for the D. ascendens x schwackei crossing i´ve used the form from ´Bandeira Peak´ with these undulated leafes, because this form in my eyes is one of the most beautiful forms. I´m growing 9 D. ascendens forms from several states and none of them shows such undulated leafes.

The first 3 pictures are showing in my eyes the possible hybrid, the last 2 ones the "common" D. ascendens from `Bandeira Peak´. All my other D. ascendens from ´Bandeira Peak´ (more than 25 plants) have undulated leafes, but they are much more narrow than the leafes of these 3 plants. So in my eyes the 3 plants are definitely not looking like "normal" D. ascendens from ´Bandeira Peak´. And what about the much shorter stipules that are also not deep red coloured as in D. ascendens ´Bandeira Peak´?

In this case i´ve used D. schwackei as a pollen donator.

But since a few days i must say that i´m really extremely sure that this crossing has worked because of the emerging flower stalk, would perhaps a hairy flower stalk dispel all doubts?

So you think it´s better not to show any pictures of new created hybrids?

About the other crossings, i´ve tried really a lot, so it´s a relatively long list, perhaps it´s better to send you a mail these days.

You are absolutely right, it´s really hard and time consuming work.

D. camporupestris as a pollen donor also has not worked in all my tries with: D. ascendens, tomentosa var. glabrata, tomentosa var. tomentosa, graomogolensis, neocaledonica, oblanceolata, capensis.

A cross between D. roraimae and D. capensis has also not worked.

Have you been able to use D. camporupestris as a pollen donator?

Best regards,

Dani

Hello,

Really interesting not-fertile pollen due to hormonal treatment. Can you described a little more Andreas?

I was thinking about this pollen infertility today. I'm cultivating pollen in vitro at least once a week. I tested and optimized this technic and was able to germinate and cultivate pollen from various species. Of course, it works very well with Arabidopsis thaliana, but it works also with Primula vulgaris, Reseda lutea, Veronica persica, etc... I have to admit that I never tested Drosera pollen but it should work well too. If you want me to test Drosera schwackei pollen germination rate, you can send me a mature anther. If pollen tubes appear, then it should be only a self-crossing inhibition mechanism, and an incompatibily with other south-american species if you don't get any hybrid.

Hello Andreas & Daniel,

But isn't Thomas' original plant from seed/ plants he collected in Diamantina in the late 80's?? I don't believe they passed through TC.

>BUT I did easily get viable seed from selfed flowers of a seed-grown D. schwackei from Cipó this season (that's the seed you have sent to me a few years ago Fernando!). Thus I assume that the plants originating from Thomas Carow's collection somehow are a sterile clone, due to whatever reason.

D.schwackei from Serra do Cipó? I believe you mean Diamantina (I've only seen this species in the N extreme of the S.Cipó, in an area called Congonhas do Norte, and I did not get seeds). Either way, it seems a strange coincidence that Thomas' original plant (supposedly no TC) was sterile as well as Dani's (possible TC).

You mean you fathered all these babies and never followed up to see if they were being raised correctly by their adoptive parents????? :)

Very interesting!! But do you really consider the Brazilian ones are "feathery" or "knobby"? I'd say most seem to be somewhere between knobby and fan-shaped.

Ha! Amazing strategy! :)

I haven't seen this, please send me a copy!

Hmmm, I disagree... Take another look at the leaf & lamina shapes. Plus, considering they came from a mother D.ascendens like the one in shown in the picture...

>I have observed this kind of undulate leaves in several location forms of D. ascendesn so far, at least when they are in full growth (for example very obvious in the plants that Stefan Ippenberger distributed as D. ascendens originating from "Bandeira Peak" (and as "D. villosa" in the very beginning).

Which discussion was this?

Ah, this reminds me of something Dani! Andreas, did you not see the type herbarium of D.yutajensis and conclude that it was different than D.sp.Duida? In fact, I think you were gonna send me a copy of the pic of this type...

>But since a few days i must say that i´m really extremely sure that this crossing has worked because of the emerging flower stalk, would perhaps a hairy flower stalk dispel all doubts?

Some D.ascendens forms have slightly hairy flowers stalks near the base, but I'd love to see your pics! :)

>So you think it´s better not to show any pictures of new created hybrids?

No, please do!!!!!!!! :)

[Daniel O.]

Hello all,

i was also thinking that Thomas plant/s has been grown from collected seed.

Fernando, till now i´ve not seen any D. ascendens with slightly hairy flowers stalks near the base.

From which location are these plants and do you have pictures of them?

About my plants, they have very hairy flower stalks and they are not hairy only at the base. The hairiness is comparable with the hairiness of D. tomentosa var. tomentosa or D. schwackei.

Fernando, if you are interested in a list of all my crossings ("tries?") till now i can send you a list. Not all of them have germinated till now.

This year i´ve pollinated he first flower of D. schwackei with a D. capensis "all red form" and it seem to have worked, the seed capsule is swelling, the following (selfed flowers) are not really swelling till now.

In a few hours i´ll be home again and i´ll take a few pictures off the emerging flower stalk.

Best regards,

Dani

[Fernando Rivadavia]

Hello Dani

>Fernando, till now i´ve not seen any D. ascendens with slightly hairy flowers stalks near the base.

I probably do, but not sure. It's actually not a rare charcter, but they are usually very few near the base. One form, from the Pico do Itambé mountain near Serro (just S of Diamantna) is especially hairy.

>About my plants, they have very hairy flower stalks and they are not hairy only at the base. The hairiness is comparable with the hairiness of D. tomentosa var. tomentosa or D. schwackei.

Sounds beautiful, I can't wait to see pics! :)

>Fernando, if you are interested in a list of all my crossings ("tries?") till now i can send you a list. Not all of them have germinated till now.

I certainly am interested!

>This year i´ve pollinated he first flower of D. schwackei with a D. capensis "all red form" and it seem to have worked, the seed capsule is swelling, the following (selfed flowers) are not really swelling till now.

Wow, this will be a beauty for sure!

Hello to all,

great discussion... I would have one note, you discussed the pollen viability of some species (especially D. schwackei from TC). I know, that on our university is used some colour (i can`t remember the chemical composition, but i can ask about that) to study viability of Hieracium pollen (along with other methods). Under a microscope you can see different coloration of viable and dead pollen grains - you can see if there is even some viable pollen. It is a simple method and seem to be quite reliable, it should work even on Drosera pollen.

Adam

[Daniel O.]

Hi all,

Adam, really interesting idea, perhaps this method would work.

But it´s too late, the plant is not any longer in flower, my smaller plants for sure will not flower this season.

And another thing, i don´t think that´s a pollen problem.

In my eyes this hybridisation i´ve made has worked, so the pollen should not be the problem.

Fernando, it would be great if you could find any pictures of this hairy form because i´ve not seen any before. All my forms (not all of them have flowered till now) are not hairy at all.

BTW, the flower stalks of the ´Pico de Badeira´ form are not hairy at all.

I´ll send you my list these days.

What do you say about the hairiness of this flower stalk?

I really hope that the crossing with D. capensis has worked too.

And here are the new pictures, the focus was on the the flower stalk:

That is a hairy scape, what a beautiful plant and picture. I really enjoy watching pictures of your Drosera collection and hope I will be able to grow plants as nice as yours next year, when I move to the highlands.

Many thanks Sebastian.

After moving to the highlands it should not be a problem, the climate for sure will be better for a lot of your plants.

Dani,

Sorry but I think I only hare printed pics showing this character, no digital. And I won't be home until the end of the month, thus can not scan the pics until then...

Fernando

[Andreas Fleischmann]

Hello Fernando and Daniel,

Dani, even some D. ascendens in cultivation do have hairy scapes, for example the plant Thomas Carow sold as "D. villosa 'large'" some years ago, which is was called to be from "Ribeirão Pires, São Paulo" later. A very dark red form with broad lamina that is densely whooly hairy on the lower sirface, and with very short stipules and very short petiole. Your D. ascendens x schwackei reminds me a lot of this plant! ;)

Do you grow that special form of D. ascendens? Did you notice the very hairy scapes in this one? Take care, the hairs of that D. ascendens are deciduous, thus will not be noticed in flowering specimens ;)

But you will be able to convince me of your hybrid when the flowers open! ;) If the stigmas are flabellate, it's no doubt a cross with D. schwackei.

Take care using the location "Bandeira Peak" for this D. ascendens! That's the plant Stefan Ippenberger got without location data (as far as I remember), and he showed photos of this plant as "D. villosa" on this forum. Fernando coined in that this was D. ascendens of course, and that it reminds him most of the plants he had found at Pico do Bandeira. That's how this form got it's name. But it is a very large form however. Fernando, didn't you mention the plants from Bandeira peak were actually quite small?

Here's a thread by Stefan Ippenberger from 2004, where Fernando doubt's that the large plant is in fact from Bandeira Peak: "D. villosa Bandeira Peak"

See this photo by Stefan: http://freenet-homepage.de/byblis/dvillosagraoascend3p.jpg

Dani, the plant in the left upper corner is the D. ascendens from "ex Ribeirao Pires", which Stefan calls "100km SW of Sao Paulo". Do you notice the hairy scapes?

Later,

Andreas

Edited October 17, 2009 by Andreas Fleischmann

[Daniel O.]

Hi Andreas,

yes, i´m growing these plants from ex. "Ribeirão Pires, São Paulo" as well, but they are looking totally different in my eyes. They are really very dark red (more violett) coloured but my plants from this location have not flowered till now nethertheless they are adult. So i don´t know the hairiness of this species.

Here an older picture of my ex. "Ribeirão Pires, São Paulo":

The plant with the emerging flower stalk i´ve shown yesterday has much shorter leafes (different leaf and lamina shapes) and a more compact rosette (and very short stipules) and much more undunlated leafes in comparison to plants of this "Bandeira Peak" form.

The flower stalks of all my seed grown plants from my motherplants of the "Badeira Peak" form are completely unhairy.

Here an older picture:

You are absolutely right, the plants from this "Bandeira Peak" form are really huge in comparison to a lot of other location forms. But perhaps they are looking different to the plants in nature because of other growing conditions. Also the plant from Stefan Ippenberger you have mentioned is looking very different to the plants i´m growing, his plant seem to have not so undulated leafes like my plants from this location, the diameter seems to be the same.

And his red coloured plants are also very different in comparison to my possible hybrid.

And who can guarantee that these plants are not perhaps crossings with D. tomentosa var. tomentosa, is it really sure that these plants are not natural hybrids?

How are looking their flowers?

And why the flowers of this possible hybrid should be flagellate in your opinion?

Best regards,

Dani

All of the plants that you have photographed are wonderful. You have inspired me to give S American Drosera another try.

[Fernando Rivadavia]

Hello Andreas & Dani,

>Take care, the hairs of that D. ascendens are deciduous, thus will not be noticed in flowering specimens ;)

This was very confusing for me when studying herbarium of Brazilian Drosera, hehehe!

>But you will be able to convince me of your hybrid when the flowers open! ;) If the stigmas are flabellate, it's no doubt a cross with D. schwackei.

Hmmm, I gotta take a look at some of Rolf Grantsau's drawings to see the variation in D.ascendens stigmata...

>Take care using the location "Bandeira Peak" for this D. ascendens! That's the plant Stefan Ippenberger got without location data (as far as I remember), and he showed photos of this plant as "D. villosa" on this forum. Fernando coined in that this was D. ascendens of course, and that it reminds him most of the plants he had found at Pico do Bandeira. That's how this form got it's name.

I do not remember this at all... And I would not have recommended any addition of location data if there was no proof.

>But it is a very large form however. Fernando, didn't you mention the plants from Bandeira peak were actually quite small? Here's a thread by Stefan Ippenberger from 2004, where Fernando doubt's that the large plant is in fact from Bandeira Peak: "D. villosa Bandeira Peak"

This I do remember. I never thought these plants in cultivation looked anything like the ones that grow at Bandeira Peak, which were truly very small. If in fact they did not have location data initially and at some point I said they looked like the ones from Bandeira (maybe when they were babies), then I think this is a case of misidentification. I wouldn't risk adding location data to plants which did not previously have any, especially from such a polymorphic species.

Therefore, if this is truly how these plants got the location data added to their name, I would recommend immediately starting a "campaign" to remove that info from the labels. If anything, these plants look like the form that grows near the border between the states of Paraná and Sao Paulo, near towns like Itararé, Sengés, Castro, and Jaguariaíva. BUT... please do not add this to any labels if you are not sure of origin, let's not start another wave of mislabelling, hehehe! :)

Andreas (or Stefan?), can you confirm for us that these plants truly did not germinate from seeds with certified location data and that the "Bandeira Peak" was only added afterwards?

Thanks,

Fernando Rivadavia

[Daniel O.]

Thanks Greg, you should try it again. For me the shouth americans are the most beautiful species.

Hi Fernando,

Take care, the hairs of that D. ascendens are deciduous, thus will not be noticed in flowering specimens

Do you mean they are loosing the hairs before flowering?

I´ve received the plants from Kamil several years ago with this location data (Bandeira Peak), but of course i cannot be sure if it´s correct.

As you can see the plants i´m growing under this location data are really very huge, but perhaps they are getting much bigger under other growing conditions in comparison to the conditions in nature.

This form seems to develop much faster stems than other forms i´m growing and my plants are relatively old. They have needed a lot of years to reach this size.

The plants i´m growing under ´Itararé´ location data are looking different and they are much smaller in diameter.

In the moment i´m not at home so i can´t show newer pictures and for sure the plant is now in flower, but the next 2 plants will perhaps flower a little bit later so i hope that i can show detailed pictures of the flowers in future.

For the moment here is a last picture of the emerging flower stalk i´ve taken 7 days before today (it´s not the best picture).

This time i don´t have asked my mother to take newer pictures after the accident with D. cayennensis last time.

In my eyes this flower stalk is looking totally different in comparison to the flower stalks of the plants i´m growing as ´Bandeira Peak´ (the parent of the possible hybrid with D. schwackei).

Greetings from Sofia,

Hello Dani,

Yes, the hairs tend to fall off the scapes with age and by the time it's dry you will often not see any at all.

The plant is looking beautiful, good luck!!

[Daniel O.]

Hi all,

i´m back again from Sofia, it has really been a great time out.

The first few days i´ve had to spent a lot of time for my plants, cutting old flower stalks, removing sphagnum and so on.

Today i´ve had a little bit time to sort some of the pictures i´ve taken the last few days.

Here are a few D. schwackei pictures:

Perhaps some of you remember that my plant doesn´t wanted to produce seed last year after selfing.

Andreas F. reported that he has had the same obversations with this "old clone".

First of all, I can only second Thomas' and Daniel's obervations: I did not a single seed grain from this "old clone" of D. schwackei (which I, like Daniel, got from Kamil Pasek of bestcarnivourosplants, who grows it from tissue culture). This D. schwackei and the D. "yutajensis" from Duida (from tissue culture of Joachim Nerz) are the only (!) two South American Drosera in my collection that never produced any seed from selfing, nor when I used them as pollen donors for crossing experiments! Problems in pollen meiosis are known after hormone treatment of plants, likewise are infertile triploid plants.

Now the interesting thing is that my plant has produced seed this time (of course i´ve tried to self them again), not a lot, but it´s looking good and healthy. A part of them i´ve sown out these days and of course i hope that they will germinate.

I´ve had the same problem several years ago, when i´ve received D. camporupestris and D. chrysolepis from Kamil (tissue culture), the first time they have flowered there was no chance for selfing them, absolutely no seed. The next season this problem disappeared somehow.

So this problem seems to be reversible.

@Andreas, what about your plants from this "old clone", have they produced seed this season after selfing? Have you tried it again?

And here are again some pictures of the "possible hybrid" with D. ascendens. All the 3 plants in my older pictures have these hairy flower stalks (less than D. schwackei, similar to D. tomentosa var. tomentosa), the "normal" looking D. ascendens (all my D. ascendens with this location data are looking very equal) in the same pot have not flowered yet, they are much slower growers and are forming little stems.

Tomorrow i´ll show several pictures of the flowers (different views), now it´s too late, i have to sleep a little bit.

And here is again a picture of the motherplant of this "possible hybrid" (they have started to flower these days). All my seed grown plants from this location (Bandeira Peak?) are looking nearly identical and have absolutely no hairs on their flower stalk, they are slightely glandular (the focus was on the flower stalk).

Best regards,

Dani

Drool... fantastic looking plants!

[Fernando Rivadavia]

Hey Dani,

A good way to confirm the hybrid is to look at the shape of the seeds -- if it produces them. But even if no seeds are produced, that's still a good indication that they are probably hybrids.
