2. JUSSIAA, Linn.; Benth. et Hook. f. Gen. Plant. i. 788. 
Calyx-tube elongate cylindrical or prismatic, not produced above the 
ovary; limb 4—5-partite. Petals as many as calyx-lobes. Stamens 
twice as many as petals. Ovary 4—5-celled; ovules oo. Capsule de- 
hiscing septicidally or the thin pericarp irregularly rupturing. Seeds 
oo, in some species singly enclosed in free at length dehiscing segments 
of the dry endocarp.—Herbs or frutescent. Leaves alternate, usually 
entire. Flowers yellow or whitish, axillary, solitary, sessile or pedun- 
culate. 
A considerable genus, affecting wet localities throughout tropical and subtropical 
countries. Many of the species are very widely diffused, and their synonymy 1s "The 
entangled. I have not attempted to unravel this for the present purpose. @ 
synonymy of some of the species is treated of by Grisebach (Flora British W. Indies), 
Bentham (Flora Australiensis, iii, 307), and Wright (in Journ. Linn. Soc. x. 474).
