[Aroid-l] arum question

From: crogers at ecoanalysts.com (D. Christopher Rogers) on 2007.09.17 at 16:04:19(16303) Hiya Tony, Yes I agree! I forgot to mention that the plants that postpone and then abbreviate dormancy are typically sporting smaller leaves when they emerge again. This does not seem to be a positive strategy for the plants. Cheers, Christopher +More D. Christopher Rogers Invertebrate Ecologist/Taxonomist ((,///////////=====< EcoAnalysts, Inc.
