Hi Charles

Back in the Chen Yi days I corresponded quite a bit with Guy Gusman, before
his first book appeared, and recall that he was having difficulty sorting
out the 2 species in question. At one point he suggested that we might
combine the 2 names into "franchesii" or "fargetianum"!

The few Chen Yi arisaemas that have survived here are still as confusing.

I still have a few of her plants of various species doing well here,
particularly Podophylum/Dysosmias, and some Epimediums. Most of the rest
are history.
