compressed on its faces, the condyle being internal and intru- 
ding, thus rendering. the cell hippocrepical and 4-locellate by a 
monstrous expansion of the intruding condyle—a formation 
which it is difficult to understand : the seed is said to be hippo- 
crepiform, but whether with or without albumen is not stated, 
nor is the shape of the embryo known. The genus must for the 
present therefore be referred to the section made to include those 
of doubtful position.

This genus is proposed for a plant in the Hookerian herbarium, 
obtained from the Collection of the East-India Company, and 
registered as from the Helford herbarium: no locality is stated ; 
but it may be presumed to be of Indian origin. It has ovate 
leaves, rounded at the base, acuminated at the summit, 3-nerved 
as well as triplinerved, the nerves extending beyond the middle 
and archingly anastomosing with the few other lateral nerves ; 
the petiole is short and slender. The inflorescence consists of
