Obs. The American species of this genus, viz. Echites 

 corymbosa Jacq. floribunda 8w. and spicata Jacq. differ 

 considerably from the rest, which are natives of New Hol- 

 land and New Zealand. Among these, the only published 

 species is Periploca capsularis, Forst. prod. n. 126. When 

 the fruit of all has been examined, they will probably be 

 divided in the following manner : 



t Americance. Ovariis duobus. Folliculis distinctis. 

 tt Australasienses. Ovariobiloculari. Folliculis longi- 

 tudinaliter cohserentibus. 



The genus is named in memory of Dr. James Parsons, the 

 author of a Dissertation on the Analogy between the Pro- 

 pagation of Animals and that of Vegetables, and of an 

 unfinished work, entitled, " The Microscopical Theatre of 

 Seeds." The Parsonsia of Brown, which Linnaeus reduced 

 to Lythrum, is a species of Cuphea.
