We have only seen the plant bearing 
this name in the collection of Messrs. 
Loddiges, from which our figure is taken, 
and which, as it does not agree very well 
with the specific character, is perhaps 
not the true plant. At all events, the 
plant figured is handsome, and as vigo- 
rous and hardy as Ampelépsis bipinnata. 100,’ Gesumoribatiites
