Title: Unknown Aroid from Barranco do Velho, Algarve (Portugal)
Post by: aristoflora on December 03, 2015, 04:10:04 PM: Hello!

I got some tubers of this aroid species from my last holiday trip in the Algarve - but unfortunately I can't identify the species more precisely. Is there anybody having an assumption what it might be?

Thanks in advance,
aristoflora

Post by: aristoflora on December 03, 2015, 08:59:22 PM: I think you're pretty close! But A. italicum has 4 subspecies .... and there is another one A. cylindraceum obviously being quite similar...
How can I distinguish those species? Is it only possible through flower characteristics?
