Re: Re: SPEC: Iris lazica

I believe it is difficult to distinguish the species based on flowers though
lazica is supposed to have "larger fiddle-shapped falls". You might
try comparing leaves. unguicularis has thicker, stiffer leaves with strong
ribs particularly along the edges of the leaves. lazica is only weakly ribbed.
If you run your fingers along the leaves; they feel different. unguicularis is
very stiff; lazica only slightly stiff. You might also look at the base of the
leaves. I'm not sure if it a univerisal characteristic, but unguicularis leaves
just come out of the ground and it can be difficult to see leaf "fans". In
lazica the fans are much clearer.

Do you have different cultivars of I. unguicularis? It might be interesting
to compare their leaves to see how much variation they have. I have a
few cultivars, but most are recent and don't have many leaves to look
at..
