    New Drosera species from Brazil: Drosera magnifica

    Hey guys, the black mass you see are mostly dead leaves clinging to the old stems, not roots. Best wishes, Fernando Rivadavia P.S. I'm feeling lazy to repost pics, so feel free to google them or check out the ICPS or Drosera page on Facebook. ;)

    Drosera graminifolia and D. spiralis, re described..

    Hey sorry for the late reply! AFAIK no Brazilian sundews are self-incompatible, although I have heard many complain over the years that they do not get seed. Maybe it's a humidity thing? Try the Andreas Fleischmann strategy: cut the styles short and add pollen to the stumps. This way, the...

    Any experience with U. arenaria

    U.arenaria usually comes up easily from seed. Too easily. And soon takes over every single freaking pot you have with its ugly dead scapes. If you're lucky, your seed will not germinate. Ever.

    what am I looking at?

    Hello everyone, That's D.sessilifolia alright. The longer petioles on these specimens are clearly a result of them growing semi-aquatically. As for the overall size, well.... it's still a huge mystery to me why D.sessilifolia grow so large in the wild, but in cultivation resemble a weak...

    Article: Elucidating the D.montana complex

    Hello everyone, Here is another call to correct your plant labels! :) A few colleagues and I have just published a 35-page review of the D. montana complex. Like our previous publications on Brazilian sundews, this paper has been decades in the making and it has definitely been the most...

    Rarity of Genlisea

    Hey guys, You can find pics of Genlisea in the wild on CPUK forum (http://www.cpukforum.com/forum/index.php?showforum=30) and the Brazilian CP forum (http://www.plantascarnivorasbr.com/forum/viewforum.php?f=27). But all the known CP pics can be found on the CP Photo Finder...

    Rarity of Genlisea

    Well I can tel you they are definitely not rare in the wild - if you know where to find them. Most of the species I have seen in S.America and Africa were at least locally very abundant in multiple populations, often forming huge carpets (G.violacea, G.aurea, G.repens, G.filiformis, G.africana...

    Utricularia praelonga?

    The above plant is U.blanchetii, not U.praelonga - although both are Brazilian. Best wishes, Fernando Rivadavia

    The D.villosa complex, now with 6 species! (get ready to change your name tags)

    Thanks Mark! Now the next big steps with this group are to study the phylogenetic relationships between the species in this group and other closely related groups, as well as to study in depth the relationships between all the different D.latifolia morphotypes across the huge geographic range...

    The D.villosa complex, now with 6 species! (get ready to change your name tags)

    Thanks! ;) I'm sure D.latifolia and D.graomogolensis are in cultivation around here, but don't know about the other ones. I know the others are in cultivation in Brazil and Europe, at least. I don't have them myself. Check the growlists here and on other forums to see if anybody has any to trade.
