Stem twining, climbing over small shrubs. Leaves large, opposite, 

 -Vvlth tlie wliole plant pubescent, Floicers in a^illarj mnbels. Co^ 

 Tolla 5 parted, of an obscure yellow colour ; lobes oblong, obtuse. 

 Crown rather longer than the coipuscle ; the 2 lateral teeth of each 

 lobe small, linear, the intermediate larger. Stigma depvessedj s\> 

 that the pollen mas.es extend horizontallj. 



Small as this genus is, I have arranged the species witli much hesi- 

 tation, and made the references with uncertainty. I have found, (my 

 observations however have been desultory), this species, distinguished 

 by its large and rounded leaves, always beariiig hispid fruit i and on 

 a label accompanying a specimen of this plant from Br. Baldwin, he 

 has written "fruit hispid," Yet Michaux dcsx^ribes his G. macro- 

 phylhis as having follicles ^* costato-angulatis j" and Walter ascribes 

 to his V. gonocarpos tlie leaves that apparently belong to this species. 

 Perhaps some intermediate species are yet to be nude known. 



Grows in light soils. 



Flowers June — August. 



The root of this species, and probably of the others, acts on the 

 bowels in a manner similar to eolocynth.
