110 SAPOT.E. [CI. 8. 



Oixhidece, Ord. 2 1 , and deposited by the Anther upon 

 5 appropriate prominences of the pentagonal Stigma, 

 which is common to the 2 Styles. These Plants con- 

 stitute a new Order, named Asclepiadea:, of which 

 Ceropegia, Staprtia, Pergularia, Asclepias, Cy nan- 

 chum and Periploca are examples. Mr. Brown has 

 38 genera in all, the original Stapelia being greatly, 

 perhaps too much, subdivided. Of the remaining 

 Apocinece, whose Pollen is granular and conveyed in 

 the usual way to the Stigma, Mr. Brown has 15 ge- 

 nera with feathery Seeds, among which are Echites, 

 Apocynum and Nerium. Of those whose Seeds, 

 though sometimes winged with a membrane, are not 

 feathery, such as Vinca, Plumieria, and Cameraria, 

 he has not yet published any particular illustration. 



The leaves in both Orders are simple and entire. 

 Inflorescence of Asclepiadece aggregate, lateral, be- 

 tween the Footstalks.
