ON THE ASCLEPIADEJS. 



Stigma muticum. 



Folliculi subcylindracei, Iseves. Semina coniosa. 



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 8. 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.

 lagineo-pellucido.

Folliculi 



Habitbs Stapelise.

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 

 saidpulla 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 ce apice simplices.
