and on a new Genus of the Family Balanophoree. 103 
Langsdorffia of Martius * (not Arnott t) differs in the absence of the areo- 
lation and the peculiar hairs, the stalked ovaria crowned with papillz, and the 
highly developed stigmatic surface. With the females of both Helosis and 
Scybalium 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 Scybalium to be actually bilocalar. 
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 Scybalium, to 
be described as inferior, may originate in an early development of the pa- 
pille. 
To endeavour to make this account of Balanophora and Pheocordylis more 
complete, I subjoin distinctive characters of the genera to which I would at 
present limit the natural family Balanophoree.
