[Aroid-l] Anchomanes

From: "D. Christopher Rogers" crogers at ecoanalysts.com> on 2006.10.20 at 16:18:51(14753) Hello, I am new to the list, and I look forward to learning from the various discussions herein. My interests lie primarily with the tuberous aroids although I have a soft spot for Alocasias. I mostly grow Arum, Arisema, Dracunculus, Helicodiceros, Amorphophallus, Anchomanes, Typhonium, Gonatopus, and the like. I am looking for Biarum, Arisarum, and Eminium. Anyway, here are my first questions: I was given a plant recently that appears to be a young Anchomanes. It is only about 60 cm tall. It has the typical tuber, spiny petioled, dracontioid leaf, and the slowly dividing pinnae. The petiole is purplish green, with a pale spot above each spine. Is there any way to identify the species at this stage or do I have to wait until it matures and flowers? Are there specific characters that I should look for? Three species are listed on the IAS web site, are there more? I have A. difformis, and it differs from the specimen at hand in having a green petiole. Any information, citations, references would be helpful. Thanks in advance, Christopher +More AUTOTEXTLIST \s "E-mail Signature" D.
