" An c. cujanensis? Fohis quinatis, pedunculis trifloris umbellatisque. Capsula, 4-locu- 

 lari, loculis monospermis. Corolla alb4. Totd planta valde hirsutd. 



° CoroUei atro-purpurascente. Pedunculo valdd inflato. Caps, obscure tetragona, ssepius 

 3-loculari, seminibus magnis, lateribus compressis, ad hilum maculatis, et odore fsetidfl, 

 embryone magno, viridi, et vald^ plicato. Foliis cordatis, acuminatis. Caule volubile, cum 

 squamis parvis, irregularibus. The natives call it Leramy-lemmy, signifying black lips, and 

 use it as a strong purgative ; Mr. Malcolm Ritchie tried it with success in several instances, 

 and in one case administered a large table-spoon full of the powdered seeds, which continued 

 to operate gently, and without pain, for three days. The principal objection to it as a remedy, 

 is the quantity necessary to be taken, as it is very nauseous. I suspect there is more than 

 one species.

 of the world, as in Peru.
