This is altogether a doubtful plant, and is only known from 
the figure given by Zanoni in his ‘ Istoria Botanica,’ p. 170, t. 78 
(1675), under the name “ Rumphal pianta orientale,” which has 
been copied in later works by other authors. Zanoni gives India 
as its habitat, and Louriero’s Chinese plant may be different. 
The plant figured by Zanoni is certainly not an Arisema, but 
probably some species of Typhonium, badly drawn.
