and on a new Genus of the Family Balanophorese. 103 



Langsdorffia of Martius* (not Arnottf) differs in the absence of the areo- 

 lation and the peculiar hairs, the stalked ovaria crowned with papillae, and the 

 highly developed stigmatic surface. With the females of both Helosis and 

 ScybaUum it agrees in the structure of the hairs and of the fruit, although the 

 ovarium of both these genera evidently appears to be composed of two car- 

 pella, and that of ScybaUum to be actually bilocular. 



The nakedness of the apex of the ovaria, connected with the papillose ap- 

 pearance of the apex of the fruit, seems to me to indicate that the appear- 

 ances which have caused the ovaria of Helosis, and especially of ScybaUum, to 

 be described as inferior, may originate in an early development of the pa- 

 pillae. 



To endeavour to make this account of Balanophora and Phceocordylis more 

 complete, I subjoin distinctive characters of the genera to which I would at 

 present liuiit the natural family Balanophorece.
