We had no opportunity of inspecting the specimen from 

 which the di'awing 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 

 rmsed, as we are informed, fi'om 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 Convolvulus 

 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 root was tuberous, as in
