Joseph Clemens Posted September 23, 2006 Report Share Posted September 23, 2006 I've always appreciated the appearance of Drosera cuneifolia but was never able to obtain this species. Recently, however, I obtained some seed of Drosera admirabilis from Seandew and a potted plant of the same species, from a visit to California Carnivores. The seed is growing nicely and so is the potted plant. My question is, what is the consensus concerning the identification of this species? Is Drosera admirabilis the same as Drosera cuneifolia? Or are they different, though similar species? Quote Link to comment Share on other sites More sharing options...
Christian Posted September 24, 2006 Report Share Posted September 24, 2006 (edited) Hi, in my opinion, Drosera admirabilis and Drosera cuneifolia are two completely different species. They do not at all look like each other, if you compare adult plants, grown side by side. Drosera cuneifolia is twice the size of admirabilis. They are also significantly different in the flower parts and the stipule. I think, i have posted this picture before on a similar topic, but here it is again: Christian Edited November 7, 2015 by Christian 1 Quote Link to comment Share on other sites More sharing options...
V.J.Treasure Posted September 24, 2006 Report Share Posted September 24, 2006 Same as Christian, I have no problems of identification between those two as long as they are no seedlings. You can see on the picture that the leaves are larger and not exactly of the same form, the whole appeareance of D.cuneifolia, especially regarding the rossette is massive compared to D.admirabilis.

Joseph Clemens Posted September 24, 2006 Author Report Share Posted September 24, 2006 Thanks Christian and Valentin for your feedback on this thread. So they are similar, yet distinct. That's good and bad for me. I'm anxious now to see if I can locate some true Drosera cuneifolia seed or plants. Quote Link to comment Share on other sites More sharing options...
jimscott Posted September 25, 2006 Report Share Posted September 25, 2006 Joseph, I have seedlings of D. cuneifolia if you are interested. Quote Link to comment Share on other sites More sharing options...
Sean Spence Posted October 31, 2006 Report Share Posted October 31, 2006 Over the past couple of weeks I have had my large plant of Drosera cuneifolia from Silvermine flower for me. This has allowed me to finally compare the flower structure of D. cuneifolia and D. admirabilis forms. A few photos. Firstly of the D. cuneifolia from Silvermine. Semi mature plant, approximately 6cms across. Taken in August. Same plant about a week ago. Hot weather and the flowerscape have taken their toll on the health of the plant. Plant about 8cm in diameter Plant in flower. Pretty ordinary shot, taken as the flower is preparing to close for the day. But you can get an idea of the size of the flowers which are about 5cms across. A shot of another, healthier looking flower. Close-up of the same flower showing the details of flower structure. Note the lack of forking of the styles. Now some shots of a couple of D. admirabilis forms and flowers. Firstly, a small form which only grows to about 4cms in diameter. A single plant grown in strong light. The flower of this form. Note the forking styles in this species. Double header of the same form. Finally the form of D. admirabilis from the Palmiet River region of RSA. The rosettes. About 5-6cms in diameter. The much paler flower with thinner bases to the petals. Note that this form also has forked styles very similar to the previous D. admirabilis form. The flower of this form are also spaced much further apart than the previous form and D. cuneifolia.

Christian Posted November 12, 2006 Report Share Posted November 12, 2006 Hi, great pictures Sean! I think, it is easy to see, that the flowers are quite different. Christian Quote Link to comment Share on other sites More sharing options...
chaffinchnz Posted July 7, 2013 Report Share Posted July 7, 2013 This was a great article back in the day! Are the previously-linked images able to be re-linked, Sean? Quote Link to comment Share on other sites More sharing options...
Christian Posted July 28, 2013 Report Share Posted July 28, 2013 (edited) Hi, in case, Sean can't put his pictures back online, you should be able to find almost everything on my homepage: Drosera admirabilis Drosera cuneifolia As a side note. Is anyone still cultivating the form from Silvermine? I lost mine last year and would love to replace it!

Marcel van den Broek Posted July 28, 2013 Report Share Posted July 28, 2013 I lost 2 of mine last year too Christian, the last one is struggeling. I'll let you know if he makes it and if I can take cuttings. Has anyone noticed that sometimes a certain location of a species just seems to "crash" in several collections at the same time, like some biological timebomb went off?

Sean Spence Posted July 29, 2013 Report Share Posted July 29, 2013 Might be a problem tracking down the images. I've still got the Silvermine form growing well but do lose a few each summer. It doesn't like the heat too much. Quote Link to comment Share on other sites More sharing options...
