Fernando Rivadavia Posted May 4, 2007 Report Share Posted May 4, 2007 Hello all, I haven't heard any news lately from people cultivating D.meristocaulis. I'm very curious, considering that 3 years have now passed since seeds were germinated and one year(?) since plants flowered. Are plants flowering? Are seeds being produced?

V.J.Treasure Posted May 4, 2007 Report Share Posted May 4, 2007 Hi, I have heard of people offering seed and maybe even plants now and then but I can't remember where and I have no proof that it was the realy species.

Guest Ivan Snyder Posted May 5, 2007 Report Share Posted May 5, 2007 Hi Fernando, My original three plants are still looking great and keep growing. I tried reproducing one plant by taking a pup off and potting it by itself. It died :cry: I guess I'm the only person to get the plant to flower from seed? --three times Ivan Hello all, I haven't heard any news lately from people cultivating D.meristocaulis.

Fernando Rivadavia Posted May 5, 2007 Author Report Share Posted May 5, 2007 Hey Ivan, At least two other people have gotten it to flower: Gert in Holland and Andreas F. in Germany (but only Andreas from seed).

Marcel van den Broek Posted May 5, 2007 Report Share Posted May 5, 2007 Hi Fernando. My seedlings did not make it :cry: Probably to low in humidity. Will give it another try when i can find some plants or seeds. Marcel Quote Link to comment Share on other sites More sharing options...
glider14 Posted May 6, 2007 Report Share Posted May 6, 2007 hmmm. Best carnivorous plants has them for 25 euros. is that right?! i would have expected them to be MUCH highter in price. D. meristocaulis {north west plateaus of Cerro Neblina, border Brazil/Venezuela} / EUR 25(Adult plants able to flower!) Quote Link to comment Share on other sites More sharing options...
Fernando Rivadavia Posted May 6, 2007 Author Report Share Posted May 6, 2007 Hey Glider, I'm surprised as well! They must have been very successful with the plants in tissue culture. In fact, I think I remember one of the guys there also got it to flower. I remember seeing a pic of a flowering plant in TC from the Czech Republic...

Hey Fernie, When I received seeds many years back I put them into TC also. I have masses of the little blighters in culture and they do extremely well, multiplying madly, even without hormones. They are normal happy little plants. They respond really well in vitro and I even noticed that they will often form new plantlets from the roots adventiously. My plants that I planted out are still under lights and have not flowered for me, though I suspect if I made the effort to grow them in the glasshouse they would. I should do that and also take some photos. Regards Quinn Quote Link to comment Share on other sites More sharing options...

Sean Spence Posted May 6, 2007 Report Share Posted May 6, 2007 I have everything but the ms media then I can tissue culture I even got the PPM biocide as a sample so I think my chances are high,I am thinking about putting my peltata seeds in vitro but I would like to try other more common things like some of my sundew leaves. I don't think I need BAP for seeds or easy drosera leaves. What temps can D.pelata handle?I was thinking in the day it could go into the 45 fahrenheit fridge then under grow lights at night because of the high temperatures. Rather than hijack the thread, perhaps you should create one of your own. This is not relevant to the topic at hand. Quote Link to comment Share on other sites More sharing options...
Guest Posted May 6, 2007 Report Share Posted May 6, 2007 Wow its been that long? 3 years wow...time does fly! It feels just like yesterday that seeds were being offered here of this new and exciting species. I hope this species becomes more available soon, as I really like the look of it. :) Good grwoing everyone! Quote Link to comment Share on other sites More sharing options...
Fernando Rivadavia Posted May 6, 2007 Author Report Share Posted May 6, 2007 Hey Starman, You're right, it hasn't been 3 but 2 years! I found D.meristocaulis in late 2004 and seeds were germinated in early 2005. Ooops! :) Best Wishes, Fernando Rivadavia Quote Link to comment Share on other sites More sharing options...
Guest Ivan Snyder Posted May 6, 2007 Report Share Posted May 6, 2007 Hey Fernando, As you know, I did not get any seed from my 3 flowers. I'm sure they got pollinated as I helped. You told me you thought my plants were not healthy or something, but I still think it's most likely they need cross pollination. Our friend Ed saw my flowers and felt they just needed stronger light to open all the way. I don't think the plants could get any more healthy than mine. Did Gert or Andreas get any seed? Ivan Hey Ivan,At least two other people have gotten it to flower: Gert in Holland and Andreas F. in Germany (but only Andreas from seed).

Fernando Rivadavia Posted May 6, 2007 Author Report Share Posted May 6, 2007 Hey Ivan, Your plants not healthy?? Far from that! They're are over-healthy if anything! :) I simply have this hypothesis that they are not self-incompatible based on their ecology and flower type. I can't say what happened with your plants however... I suspected something to do with light & humidity maybe not making conditions right for pollinization. Luckily your plants are producing pups! ;) Andreas and Gert have not reported seed production, but I'm not sure they were paying attention...

jp Posted May 6, 2007 Report Share Posted May 6, 2007 Hello Fernando I bought some seeds from Gert in Holland, I received them the 29/11/2005. They germinate fast (one month). They grow very slowly, but i'm not sure to have good conditions (I suppose they don't like hot températures!!). In spring, automn and summer I keep them outside, and in winter they are in a greenhouse with 6° min. I think they are far from making flower. I post 2 photos of the plants (they are now a little bigger) by. jp Quote Link to comment Share on other sites More sharing options...
Guest Ivan Snyder Posted May 7, 2007 Report Share Posted May 7, 2007 Hey Fernando, I suppose it is possible the conditions are not quite right. But I've never had any sundew that is growing so well not produce seed, except when self incompatible as with many pygmy species and all petiolaris. Anyway, I am glad to hear that others are having success growing the plant. It's a real beauty and grows well in captivity once it gets established. Mine have always been indoors under artificial light with no terrarium. Good luck to the rest of you. -Ivan Hey Ivan,Your plants not healthy?? Far from that!

Andreas Fleischmann Posted May 8, 2007 Report Share Posted May 8, 2007 Hello, I had just one flower in one of my D. meristocaulis so far. Unfortunately, I never saw that flower. The flower was still in bud in mid august 2006, before I left to Sierra Leone. When I came back home 3 weeks later, the only thing I found left of that flower where dried remains ;). Like Ivan, I did not get any seed from that spent flower. As I did not have the chance to pollinate that flower by hand, I cannot say whether D. meristocaulis is self-incompatible (chasmogamous) or just not selfing (autogamous). BTW, did anyone of you notice that the additional aerial roots are not growing straigt downwards (like in D. scorpioides for example), but are descending at an angle of about 30-45° ? All of my big plantlets (i.e. having stems more than 3 cm tall) have at least one of these support roots (like little carnivorous Pandanus trees ;)) I try to post photographs later on.

Andreas Fleischmann Posted May 19, 2007 Report Share Posted May 19, 2007 Hello, As I promised, here are some photographs of my Drosera meristocaulis. I hope you enjoy them: And here are 2 photos to illustrate the strange support roots I have mentioned in my previous post. Even in small plants of D. meristocaulis, you can observe the yellowish-translucent non-sticky glands on the upper surface of the petioles: These non-carnivorous glands occur in a few species of Drosera (sometimes only in a few forms of on species), scattered all across the genus: Among the pygmy Drosera, I observes these "petiole glands" in all subspecies of D. nitidula. I noticed them in some forms of D. indica (especially those originating from Queensland) and in some D. burmannii. In section Drosera, I first noticed them in D. graminifolia from Caraça (very obvious in this one!). I had a closer look at various other South American Drosera and found them in D. chrysolepis, D. camporupestris and D. montana var. schwackei, too. Well, actually it was Fernando who was pointing out the presence of those kind of glands in var. schwackei to me ;). Thanks, as this species is maybe the most poorly growing Drosera for me! My plants are over 3 years old now, they are still only about 1-1.5 cm in diameter and never had more than 2 active, sticky leaves for me. D. montana var. montana would have flowered at least 3 times within 3 years from seedling on under the same growing conditions. I really have to apporve my growing conditions for var. schwackei. Too bad Fernando did not take any notes on wind speed or temperature at Diamantina ;) ;). All the best, Andreas PS: In case my photographs are not visible to anyone again, please feel free to change the link to any of your homepages. Christian? Bob? ;) Thanks a lot in advance!

Fernando Rivadavia Posted May 20, 2007 Author Report Share Posted May 20, 2007 Hello Andreas! Very interesting photos! My guess is that these roots are an adaptation to very windy conditions on those high plateaus of Neblina. Or else to hold the plants in place during occasional water overflow along streams, where I often saw them growing (although they were more common on sandstone outcrops far from streams). Thanks again! Fernando Rivadavia Quote Link to comment Share on other sites More sharing options...
