D. schwackei x tomentosa var. tomentosa

Recommended Posts

Hello,

in winter 2008 my D. schwackei flowered for the first time and i´ve pollinated one of the flowers with pollen of D. tomentosa var. tomentosa and i was able to collect some seed.

For a very long time the plants have been very similar to D. schwackei. Finally they are adult and the first flower scape is emerging. The plants are about 3,5cm in diameter and they are more rosetted than D. schwackei.

Here are the parents.

Pictures of D. schwackei ´Diamantina, Minas Gerais, Brazil´ you can find here:

And here is an older picture of D. tomentosa var. tomentosa ´Morro Do Jambeiro, Minas Gerais, Brazil´.

And here is the hybrid.

It would be interesting to hear your opinion, is it really the hybrid?

Later this day or tomorrow i´ll show more detailed pictures.

Best regards,

Many thanks.

I must agree that on the first look the plants are looking more like true D. schwackei but tomorrow i´ll show some details that are not really matching with D. schwackei and these details are the reason why i´m thinking that this crossing should have worked.

I´ve tried also the reciprocal crossing and the resulting plants are looking nearly identical with the same colouration nethertheless the mother plant was in this case the nicely red colourated D. tomentosa var. tomentosa but these plants are still to small to be totally sure.

Best regards,

Dani

Thanks again.

Now i´ll present several pictures where it is clearly visible that these plants should be in fact the hybrid between D. schwackei and D. tomentosa var. tomentosa.

In the leaf apex D. tomentosa var. tomentosa ´Morro Do Jambeiro, Minas Gerais, Brazil´ is having longer tentacles with a rectangular head, looking like "snap tentacles", like for example in D. sp. "Shibata", D. tomentosa var. glabrata and D. tentaculata.

D. tomentosa ´Morro Do Jambeiro, Minas Gerais, Brazil´ (this is an older picture i´ve taken 1 year ago but here these tentacles are visible very clearly).

D. schwackei does not have these tentacles. :happy:

BTW, the D. schwackei plants that are visible on a few of the pictures are the seedlings from last year (sown out 9 months ago), now they are nearly mature and hopefully will flower soon.

And here are some new hybrid pictures, on the left side the hybrid is visible, on the right D. schwackei. Nethertheless the D. schwackei plants are only about 9 months old they have formed a bigger stem than the hybrid, the hybrid plants are about 20 months old.

Thanks again.

Fernando, have you or somebody else ever seen D. tomentosa var. tomentosa growing sympatrically with D. schwackei?

Here is a little update.

I really hope that the first flower will open these days because soon i´ll be away for about 2 and a half weeks. It would be a pity if i´m not able to take some flower pictures, i keep my fingers crossed. :smile:

The hairs seem to be longer and more dense in comparison to D. schwackei (sorry, not the sharpest picture).

Hello Fernando,

I don't remember them sympatrically, but close enough! :) The only one I think grows sympatrically is tentaculata ocasionally.

Aaah, that´s very interesting, so theoretically in nature there could exist any hybrids between these two species.

And it could be possible to cross D. schwackei with D. tentaculata as well after they are closely related.

I´ve tried a lot of crossings in the past but i´ve made the experiance that a lot of crossings are not working, good healthy looking seed was produced after cross pollination but in a lot of cases it´s not germinating at all.

It seems so as if the parents should be very closely related to get a successful crossing.

Greetings from Sofia (Bulgaria),

Hi all,

after 2,5 half weeks i´m back again in Germany.

Meanwhile 2 flowers have opened and i was able to take some pictures of the third flower. For comparison here are some flower pictures of D. schwackei.

And here are the flowers of D. schwackei x tomentosa var. tomentosa, in my eyes different in comparison to D. schwackei. :thumbsup:

What do you think?

Many thanks again. :smile:

The flowers are about 2cm in diameter (similar to the size of the flowers of D. schwackei), my D. tomentosa var. tomentosa flowers are about 1,5cm in diameter.

BTW, the 2 big plants are not looking identical, not only the colouration of the tentacles is slightely different.

The plant that is in flower in the moment has also not such a big number of these longer tentacles with a rectangular head i´ve shown before, so there seem to be some variation.

Of course i´m selfing the flowers, hopefully there will be some viable seed.

Best regards,

Dani

Here is a small update.

Nethertheless i´ve pollinated the flowers (about 15) absolutely no seed has been produced.

The plants coloured up a little bit during the last weeks, now they are looking this way.

P1190391a.jpg

The last 8 flowers (their sepals) looked somehow strange, at least one of these sepals (sometimes also 2) from each flower has had 5 long tentacles at the edge of the sepal.

I tried to take a picture of these tentacles but the quality is not the best.

Hi you all.

Only a couple of questions,i´m looking for d.tomentosa var. tomentosa (or d. tomentosa)but i only find d.montana var, tomentosa¿are them the same ?¿is this similar to say d.ascendens instead " D. villosa var. ascendens"

Cheers.
