Of all the known Brasillian taxa you have found, this is the most fascinating to me. *As I understand it, this plant is found only at the base of quartz scree, where the soil line begins and interweaves with the rock. *Is this an example of exploitation of a micro niche? *It amazes me to think that this potential species could have evolved in such a narrow microclime, and I am curious to know if it has radiated in any way from it. *Are all the instances of its occurence related to the base of the scree, or is it found in other places? *Are these isolated individuals, or members of a large population? *I am also curious to know what you regard as closest to it by way of species. *Robert sent me some 45mm photos (nice to see something not digital!) last Easter, and this plant is just amazing! *I am very interested in speciation in the remote Teupi habitats where so many species are truly endemic. *I believe this is not a hybrid, but rather a distinct taxa awaiting your publication since it produces *fertile seed, or am I wrong in this? *If you have any photos of this one not included on your website, I sure would love to see them. *Thanks for any information you might be willing to provide, and for being patient with my questions. *Maybe I will never have the plants to grow and appreciate, but at least I can learn about them!
This plant has already been described in the last CPN as D.tentaculata, by yours truly. It is not exclusive to this white-quartz-gravel-soil-meets-sandy-soil habitats, but it does like them a lot. But there are 3 species which do seem to be almost exclusive to this sort of habitat, strangely enough. And these are the 3 rarest Drosera in Brazil I believe: D.montana var.schwackei, D.sp."Serra do Cipo", and D.sp."Shibata's".
D.tentaculata is part of the montana complex, but is closest to schwackei in my opinion. D.sp."Serra do Cipo" is sort of a short intermediate between D.graminifolia and D.chrysolepis. D.sp."Shibata's" is also a montana complex, probably closest to tentaculata.
