The affinity of Smeathmannia to Paropsia of M. du Petit Thouars will probably be 

 admitted without hesitation ; and its exact agreement in fruit in every important point, 

 both with this genus and with Modecca, seems to leave no doubt of its belonging to 

 Passijiorecc, with which it agrees in habit even better than Paropsia, and certainly- 

 much more nearly than Malesherbia, considered by M.de Jussieu (in Flor. Peruv. hi. 

 p. xix.) as belonging to the same family. 



Smeathmannia differs then from the other genera of Passiftorea solely in its greater 

 number of stamina, which, however, may not be really indefinite ; and an approach to 

 this structure is already known to exist in an unpublished genus (Thompsonia) disco- 

 vered in Madagascar by Mr. Thompson, of which the habit is entirely that of Deidamia, 

 and whose stamina are equal in number to the divisions of both series of the perian- 

 thium. 



But from Smeathmannia the transition is easy to Ryania, which differs chiefly in its 

 still greater number of stamina, in the want of petals or inner series of peiianthium, in 

 tlie single style being only slightly divided, and in the form of its placenta 1 . 



And Ryania, although it has a superior ovarium, may even be supposed to be related 

 to Asteranthos and Belvisia, if the fruit of these two genera should prove to be unilo- 

 cular with several parietal placentae.
