Ray,
Arisaema zanlanscianense from Hubei (China) was described by Pampanini in
Nuov. Giorn. Ital. 22: 262(1915) on the basis of one female inflorescence
only, without any knowledge of the tuber, the foliage or a male
inflorescence. The description says: spathe tube 6 cm L; limb shortly
acuminate, 13-16 cm L, 8-10 cm wide; spadix appendage stipitate, erect, 1=4
cm L & 3,5 mm wide and, due to the aspect of the sterile flowers (neuters=)
reminding of A. clavatum.
There is no drawing of this species whose inflorescence looks large.
What one can notice is: presence of neuters, no indication of the colour =of
the spathe.
In these conditions, it is difficult to say if your plant matches
Pampanini's description.

H. Li, in FRPS, considers it as a "doubtful species".  Indeed it is a
species incompletely described, to say the least. The situation of A.
zanlanscianense  reminds me of other species such as A. nangtciangense Pa=mp
(spatha... = unknown spathe) whose original descriptions are so poor th=at
it is impossible to state that a plant, one has in hand, matches or doesn='t
match the species.  To be honest, I'd prefer, once for all, to discard th=e
names of  "doubtfull incompletely described species".

Well, coming back to our problem, you did not see the inflorescence of yo=ur
plants. But, from your description of a tall plant with a radiate leaf ma=de
of 15 leaflets ending in long threads, one could suggest something like A.
consanguineum?
Could somebody else, who also received these Kaichen's zanlanscianense,
give more details?


Marc,
Thanks for the very nice picture of Kaichen's #6. It looks like A.
bathycoleum I saw in Yunnan. However, usually the folioles are more
lanceolate and narrower. This species grows in open rocky meadows.
With regard to #5, a photo is necessary.


Tony,
You are right, according to Kaichen's photo of A. rhombiforme, the plant
matches A. franchetianum or A. fargesii. From the picture, it is not
possible to conclude, perhaps you could provide us with a photo of the
inflorescence on the WEB?
