jcz Posted July 31, 2017 Report Share Posted July 31, 2017 Hello. I have still very limited experience with Utricularia sect. Setiscapella and I ask for help by determining the following specimen. I got it from Carnivoria.eu as "Utricularia subulata" about three months ago. Soon it produced one chasmogamous and several cleistogamous flowers, more or less agreeing with those I expected from U. subulata, so I though the original labelling was correct. However, after growing a lot during the last month, I observed a vigorous growth of pinnate leaf-like organs, which I have not seen in images and descriptions of U. subulata. Now, I suspect of U. trichophylla, which may have flowers resembling those of U. subulata, even Taylor (1989) commented and illustrated the presence of both chasmogamous and cleistogamous inflorescescens. However, I did not checked the calix nerviation and I have never grown it before, so I am not sure. I will try to check the micromorphology of the bladders someday. Could you help me with the current limited data, or should I wait until it flowers again? Let´s think on the possibility that two species were mixed, this one with pinnate leaf-like organs, and perhaps the true U. subulata, since I observed also some unbranched leaf-like organs arising from the substrate. Thank you! Quote Link to comment Share on other sites More sharing options...
Mujinamo Posted August 1, 2017 Report Share Posted August 1, 2017 That's very interesting. It reminds me of Utricularia biloba, although that is impossible based on the flower. Unfortunately I don't know any other Utricularia that does that. 1 Quote Link to comment Share on other sites More sharing options...
jcz Posted August 1, 2017 Author Report Share Posted August 1, 2017 In fact, that is a really good suggestion! Among the plant offer at Carnivoria.eu there is also U. biloba, so I would not be very surprised if a fragment of that species was mixed with U. subulata. I think I am going to start two parallel cultures from a few, clean, leaf-like organs of both types, pinnately branched and unbranched, and wait until they flower. Thank you very much!

Mujinamo Posted August 3, 2017 Report Share Posted August 3, 2017 Good luck. I'm pretty curious what it turns out to be. Quote Link to comment Share on other sites More sharing options...
agamemnon Posted February 9, 2021 Report Share Posted February 9, 2021 Hi, did you still grow this species? Quote Link to comment Share on other sites More sharing options...
jcz Posted February 9, 2021 Author Report Share Posted February 9, 2021 Hi! Do you mean U. biloba? I grew it for a while, and even got it flower, but I lost it during one vacation period. I do have U. subulata. It is difficult to kill, hehe. Quote Link to comment Share on other sites More sharing options...
