In their book "The Genus Arisaema" and writing about section Franchetiana the Gusmans note that "The eophyll is a simple blade and further, leaves remain simple for many years, first developing some kind of lobes, often just outlined, eventually becoming fully separated as the tuber matures." They also note that the leaflets of A. franchetianum (they are referring to mature plants) "are completely separated while those of A. fargesii are often only tripartite, divided only in the upper part." So Brian, since your plants display such a variation in leaf form, are the tubers in your colony of A. fargesii of varying ages? Judy, in still overcast, still cooler, New Jersey
