Re: Philodendron crassinervium inflorescence

---

Aloha.

I took a quick look at Mauro Peixoto's photos and the scan of Schott's plate from Tom.  They look very different.  Ask Mauro exactly where he took those photos and request vegetative details as well.  Notice how short the peduncles in Mauro's photos are. Also the shape of the spathe differs from Schott's plate.  

Please send me the original descriptions of Philodendron crassinervium, Philodendron alternans, and Philodendron lanceolatum, if you can...illustrations as well.  Unfortunately, I cannot examine the type specimens to understand these taxa as described unless someone scans them for us or if they are in a virtual herbarium.  I can comment in a better fashion if you can forward me any original descriptions and illustrations.  

Aloha,

Leland

Tom, thanks so much for the plate. I've added it to the page.

I find it interesting Schott's plate does not appear to match your field notes on P. crassinervium or Mauro Peixoto's photo.  I have three questions.  Is Scott's drawing applicable to P. alternans or P. lanceolatum?    And more important in my mind, could Schott have described something that no longer exists in the forests of Brazil?  Or, is it possible P. alternans is truly a species since it is more often epiphytic as well as pendent while P. crassinervium is primarily terrestrial?  The plants in my own collection appear to be different and Eduardo and Marcus have both said privately they are not likely to be the same plant species.  In addition, notes and photos I've added to the page from Leland Miyano also at least appear to indicate they may not be the same plant.

Input from any of our experts would be most helpful.  And by the way, I've copied this privately to all mentioned in this note so if any of you choose to comment please include Aroid l when you respond.

Thanks as always!

Dear Steve:  We could scan Schott’s painting of the inflorescences if you would like it.
