Recently i bought a pot and i'm growing it on emersed.. Looking it up there seem to be 2 different plants going around in the trade the South American <Helantium tenellum> formerly aka Echinodorus tenellus and the North American <Helantium tenellum "parvullum">.
Actualy flowgrow is s far the only database i could find mentioning this mix up.. And says the parvullum should have a distinct different flower but doesn't give any further obvious details to properly identify the plant other than this older botanical drawing.
This alledgedly is the parvullum.
For the SA hellamtium version i can not find any proper data that looks very much different. Even googling for it shows pictures and articles seemingly erroneously mixing these 2 plants up as the same. The NA parvullum should have broader leaves, but it's not clear to me if that is only the case for the submersed grow form.
The shop i bought it from states it's the SA version, but i know this shop also to be notorios for selling erroneously identfied plants and seems not the only one.. Since i bought an almost flowering emersed version i'm absolutely in doubt about what it realy is. It kinda looks like a parvullum.. Actualy could be wishfull thinking, i hope it is, this means i might be able to cultivate it emersed and outdoors in the garden, if it's the one originating from North America.
Anyway, does anybody know to find references with clear examples of flower difference between both plants to get a definitive ID of what i have here.
Thanks..
