Attached are two shots of Arums seen in the last week or so in Sicily.

Any views on identity would be most welcome

The 2nd photo looks as a Biiarum, maybe Biarum arundanum, which I've seen in Portugal.

It seems Biarum arundanum isn't in Italy, looking at Flora Italiana website it may well be Biarum tenuifolium - here's a link to the Biarum page: http://luirig.altervista.org/flora/taxa/floraspecie.php?genere=Biarum

Thank you Simon. You have certainly put me on the right track. I looked at the Biarum text by Boyce (2008) as a follow up
https://www.aroid.org/gallery/boyce/Biarum - Boyce 2008.pdf

Seems to suggest it should be Biarum tenuifolium, if the taxonomy is still current. Boyce shows the western arundanum as a subspecies in Spain & Portugal rather than the nominate in Sicily and further east.

I think we cross-posted. Seems like B.tenuifolium has a consensus :-O

As an aside, B.arundanum is treated as a full species by Flora ibérica.

Very nice pdf. thanks. I can make one criticism regarding the notes on arundanum; it states "Restricted to terra rossa soil" - I found this on non-limestone soil by rocky outcrops of a shale type. Flora ibérica states its found on many soils and presents stable morphological differences between tenuifolium and arundanum, explaining why they are treated as different species.

Might the first be Arisarum vulgare, Friar's Cowl or something close?

Yes it might be - the leaves look good. The "hood" seems a strange shape to me though and seems to be flowering earlçy - ours here, where super abundant, aren't quite in flower yet, some leaf though.

Correction; The similar, but different Arisarum simorrhinum is ours in Portugal, see http://flora-on.pt/index.php#/1arisarum
Looks good for A.vulgare indeed
