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. Indeed, it is a synonym for many others but evidently not recognized as one. I assume by the many leaflets described that it is a form of A. consanguineum. This is indeed a prolific and hardy plant in our Bay Area gardens. -- Paul Licht, Director Univ.
