NAMED EAEFLESIA. 387 



It has been already remarked, that there is nothing [221 

 in the structure of the column in Bafflesia to enable us to 

 determine the position of the ovarium in the female flower ; [222 

 but that from another consideration there seems a some- 

 what greater probability of its being superior. If, however, 

 it were even inferior, the objection to the affinity in question 

 would not be insuperable, the relationship of Homalince to 

 Passijlorece being admitted. 



If Napoleona or Selvisia be really alhed to Passijlorece,

The affinity of Smeathmannia to Paropsia of M. du Petit Thenars 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 Passiflorecs, with which it agrees in liabit even 

 better than Paropsia, and certainly much more nearly than Malesherbia, 

 considered by M. de Jussieu (in Flor. Peruv. iii, p. six) as belonging to the 

 same family. 



Smeathmannia differs then from the other genera of Passijlorece 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 approach to this structure is already known to exist in an unpublished genus 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) discovered 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 perianthiura. 



But from Smeathmannia the transition is easy to Pyania, which differs 

 chiefly in its still greater number of stamina, in the want of petals or inner 

 series of perianthium, in the single style being only slightly divided, and in the 

 form of its placentae. 



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 unilocular with several parietal placentae.
