Paul, If you follow all of the keys in Gusman's book, this actually turns out to be a form of Arisaema serratum, either var. serratum or type 'angustatum'. I have retained the Arisaema angustatum name at the request of Darrell Probst, as this was the ID when it was originally collected. I can assure you that it is NOT A. consanguineum, which is another worthy plant for the garden. Tophat has leaves in a horseshoe shape, as opposed to the radial leaflets of consanguineum. I'm working on getting some pics of Tophat up on the wiki, and will probably file them under serratum just to avoid confusion. --Roy Paul Licht wrote: > The seeds from Roy Herold named Arisaema angustatum 'Best Tophat' sent > me to the Guzman's 'The Genus Arisaema' because I didn't recognize the > species.
