II. CUSPARlEiE SERIES. 



This series, the name of which might be modified,' contains, as the 

 preceding, plants with regular and irregular flowers. Both are found 

 united in the certain genera according to the species. Such is 



Eri/tlrrochiton Irasiliense.

Erythrocliiton: One species, frequently cultivated in our green- 

 houses under the name of E. drasiliense 3 (figs. 399-401), has her- 

 maphrodite, distinctly regular flowers. The convex receptacle bears 

 towards its summit a gynseceum, which is almost that of a Rue, with 

 five oppositipetalous carpels, free in the ovary, united into a tubular 

 style with five-lobed stigmatiferous head. But the perianth and 

 androceum present peculiar characters. The gamosepalous, tubular, 

 pentagonal, campanulate, valvate calyx is unequally cloven at 

 anthesis, 4 and then seems bilabiate. The regular, gamosepalous, 

 hypocrateriform corolla has a thick straight tube/ and a limb with 

 five lobes, disposed in the bud in imbricated pra3fl oration. The 

 stamens seem to be inserted tolerably high upon the corolla because 

 their filaments lining the tube are only disengaged from it towards 

 the throat. There are seen the free summits of five filaments, 



1 Because it is taken from the name of the 

 genus Cusparia, now abandoned.
