Dear Derek,

Sorry for the long silence, but I was in a field trip in Amazonia. Well, I havenīt used the smell as a character because I have no way to establish an appropriate nomenclature to describe it, and it is even harder to see in herbarium sheets than thorns in stems. Well, if you use the key I published in the last Aroideana in adult plants, I think it is possible to see what is being sold in USA. I have seen P. bipinnatifidum and P. mello-barretoanum growing in USA, but my sampling is restricted to Botanical Gardens (that potentially can grow old and wild-collected stocks). I have no way to say what species is being widely produced and tissue-cultured in USA, because I am not there. Anyhow, I think that any of you can do it using my key. I can even help, if needed. As an interesting example of how names can be misapplied ad infinitum happened the last time I was in USA. I could see that virtually every material comercially grown in Miami area as Xanthosoma sagittifolium is, in fact, Xanthosoma robustum. Old species are usually the most confused!

Very best wishes,


The Editor of 'Aroideana' says "yes, please" to such a paper, both for
that publication, and because it would be great to have it sorted out
once and for all for Florida.  (Is there such a thing as 'once and for
all' in taxonomy?)  Derek

p.s to Eduardo  I would like to repeat my recent question to you
publicly. The @selloum-type@ that we were working around at The Living
Rainforest had a very different smell to its leaves from that to which I
am accustomed in the common Florida plants. Any comments on odor as a
taxonomic character?
