From: Gusman Guy ggusman at ulb.ac.be> on 2005.09.24 at 11:13:12(13380) I am afraid there is some confusion as Arum jacquemontii Blume does exist. It is the only Himalayan species of Arum. See Pete's book on The Genus Arum, pp. 137-140. Nothing to do with Arisaema jacquemontii Blume. Unfortunately, I cannot help you find a commercial source as I don't know where it could be found in cultivation. Best wishes. Guy Gusman +More > >--- "C. J.
