We had no opportunity of inspecting the specimen from 
which the drawing was made while in a state fit for descrip- 
tion; and are indebted for what we have to say of it to Mr. 
Herbert, by whom this rare and very curious plant was 
raised, as we are informed, from Brazil seed. It flowered in 
the hothouse at Spofforth, the first year after sowing, and is 
‘suspected to be only annual, notwithstanding the woody 
consistence of the lower part of the stem. 
The species comes very close to platanifolia of the same 
genus, and also to Batatas (both placed under Convoivunus 
by Willdenow), the latter of which appears never to have 
flowered in this country, and the former never to have been 
introduced. As far, however, as we can judge from the de- 
scriptions and the mutilated specimens in the Banksian 
Herbarium, we think our plant may be at once distinguished 
from both by the very remarkable pubescence, as well as by 
the extension of the same over the calyx, which does not 
appear to take place in the others. 
We were not informed if the rogt was tuberous, as in
