RE: [Aroid-l] Philodendron stenolobum and P. bipinnatifidum?

From: "Eduardo Goncalves" edggon at hotmail.com> on 2005.06.30 at 20:18:27(13083) Dear Tom, All horticultural "P. williamsii" is now P. stenolobum. The real P. williamsii is a completely different species, occurring in coastal Bahia state and is rather rare. I don?t have it in cultivation and I have never seen a living specimen in any collection I have visited or It looks like a P. speciosum (or like a huge P. corcovadense), but is somewhat smaller in overall dimensions. I have collected it twice in southern Bahia and I have seen a few more collections in Herbarium. Philodendron stenolobum is only known from Espirito Santo state and is much more common, being found by me in many different localities. I don?t know when or when the confusion began, but P. stenolobum is called P. williamsii in lots of old publications (including Graf?s Exotica). Simon in his revision of Philodendron Meconostigma included P. stenolobum specimens in P. williamsii, probably because he hadn?t enough good material of P. stenolobum to be sure it was a different thing. Very best wishes, Eduardo. +More Dr. Eduardo G. Goncalves Universidade Catolica de Brasilia Curso de Ciencias Biologicas Sala M-206, QS 7, Lote 1, EPTC CEP 72030-170, Taguatinga ? DF, BRAZIL.

Date: Wed, 29 Jun 2005 19:47:05 -0500 Dear Eduardo: I suppose that any plant that I have in cultivation would fall into this category. Is most of the material that has been called P. williamsii now to be called P. stenolobum?

Dear Russ, Please, forget the name P. williamsii. The real P. williamsii from Bahia state (Brazi)l has wide leaves (more or less similar to P. speciosum) and has NOTHING to do with P. stenolobum. This confusion have started a long time ago, I don?t know why. I have collected many different populations of P. stenolobum in the wild, and there is a wide variability in leaf widht but they are always much narrower than any other sagittate leaf self header Philodendron (subg. Meconostigma). Very best wishes, Eduardo. Dr. Eduardo G.
