RUTACEÆX. 
II. CUSPARIE SERIES. 
This series, the name of which might be modifed,' contains, as the 
preceding, plants with regular and irregular flowers. Both are found 
united in the certain genera according to the species. Such is 
Erythrochiton brasiliense,

Erylhrochiton® One species, frequently cultivated in our green- 
houses under the name of Z. drasiliense® (figs. 8399-401), has her- 
maphrodite, distinctly regular flowers. The convex receptacle bears 
towards its summit a gynæceum, 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,‘ 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 præfloration. 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,
