of one cell. 



The singular petals of the male flower are only to be met with in Galearia, to 

 which genus I should have referred this plant, had not the two ovules in each cell 

 removed it to a different tribe. The inflorescence is also monoecious and axillary, 

 not terminal, and there are some other differences in the flowers, besides that the 

 joung seeds show no tendency to acquire the peculiar form of those of Galearia.
