206 ON THE ASCLEPIADEjE. 



Stigma muticum. 



Folliculi subcvlindracei, laeves. Semina comosa. 

 Habitus Stapelise. 

 Patria. Africa Australis. 



Obs. The whole of the third section of Stapelia in Will- 

 denow's edition of the " Species Plantarum," probably 

 belongs to this genus ; but I have only had an opportunity 

 of examining S. campanulata, venusta, and guttata, from 

 which the character is formed. I have named the genus 

 in memory of Justus Huernius, one of the earliest collectors 

 of Cape plants, and from whose drawings the first account 

 of Stapelia was taken.

 Columna fructificationis inclusa. 



Corona staminea simplex, 5phylla, foliolis dorso dentatis. 

 Anther a apice simplices. 



Masses pollinis erectae, basi affixee, altero margine carti- 

 lagineo-pellucido. 

 Stigma muticum. 



Folliculi 



Habitus Stapeliae. 

 Patria. Africa Australis. 



Obs. The want of the external corona renders it neces- 

 sary to separate from Stapelia and Huernia, this genus ; of 

 which the only two certain species are Stapelia punctata 

 and pulla of Masson; of both these 1 have examined spe- 

 cimens collected by Masson, and preserved in spirits, in 

 the collection of Sir Joseph Banks. 



STAPELIA. [Stapelise plures, Linn, et Mass. 



Char. Corolla rotata, 5fida, carnosa. 

 Columna fructificationis exserta. 



Corona staminea duplex, utraque in variis varia ; interior 

 quandoque obsoleta. 



Anther a apice simplices.
