Re: Epiprinopsis and Amydrium zippelanium.

Epipremnopsis is a synonym of Amydrium Schott, a genus of 
terrestrial subscandent herbs and root-climbing lianes occurring 
from Sumatera to New Guinea and from southern China to Java, 
was last revised by Dan Nicolson in 1968. Nicolson merged  
Epipremnopsis Engl. into then monotypic Amydrium and 
recognized four species in all. Since Nicolson's account two 
distinct additional species have been recognized: A. sinense 
(Engl.) H. Li and A. hainanense (C.C. Ting & C.Y. Wu ex H. Li et 
al.) H. Li. Amydrium sinense, based upon Engler's Scindapsus 
sinense, was overlooked by Nicolson as belonging to Amydrium 
although he had seen the type specimen in Berlin Amydrium 
hainanense, described initially in Epipremnopsis, was transferred 
to Amydrium in the Flora of China Araceae treatment. Additionally, 
two species recognized by Nicolson, A. zippelianum and A. 
magnificum, have since been shown to be conspecific (see Boyce 
1995). Amydrium as here defined comprises five species.


There was a nice plant portrait of Amydrium zippelianum in Curtis's 
Botanical magazine Vol. 12(2), pl. 269 (1995) with cultural details. 
Amydrium zippelianum is in cultivation in the US. I've seen bigs 
plants at Monroe Birdseys place and various collectiosn ahve 
younger plants. It's often grown as Amydrium magnificum.
