Dear Steve:


Schotts drawing is of P. crassinervium.  Yes thing  have gone extinct after having been described.

I collected P. crassinervium in 1996 between Mangaritba and Angra dos Reis, R de J, Brazil in lowland more or less undisturbed (rare!) Atlantic Forest. I do not believe that it and the P. alternans that I received from Leland are conspecific.       HEL

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!

Steve Lucas
