Paul, Arisaema aridum is spelled correctly in the AEG Arisaema Species List but is misspelled (3 places) in the Flora of China Key as you have discovered thanks to Guy. I've corrected it and will copy Roy on this E-mail to bring it to his attention. Guy will see it on Arisaema-L. I'll accept 6 lashed with a wet noodle. Ray <GRSJr at Juno.com>
