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

Hi! I think that this is Arum italicum.

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?

Was it lifted from the wild?

Yes it was - naturally it grew in very dry soil near the river of Odeleite (but the region is very dry in summer, only humid in winter & spring)
