ID Help

[Richard Fraser]

Hello experts.  I have been trying to ID these plants described below.  They
originated from the NARGS seed exchange  Labeled as Arisaema franchetianum.

This species has tall snakeskin-mottled stems at least to 60cm. one
sometimes two   classic radiatisect leaves with narrow, numerous, leaflets
(varies from 9to 29 on seven plants that I forced for IDing)  Each leaflet
ends in a7-10cm drooping thread like tip.Spathe brownish with lid which
terminates with a thread like tip.  Spadix is mottled brown and is like a
fattened tongue depressor.  Tuber resembles that of A.flavum.  Any guess?
