Calyx-tube very short, segments 5, imbricate in wstivation. Petals 
5, subequal or the anterior larger, imbricate. Stamens 10, all perfect 
and subequal or 3 or 5 wanting or imperfect ; anthers uniform or 2 or 
3 anterior larger, 2-celled, dehiscing by terminal pores or longitudi- 
nally more or less from the apex. Ovary sessile or stipitate, frequently 
arcuate; style short or long; stigma terminal; ovules several or 
numerous. Legume terete or flattened, indehiscent or 2-valved, with 
or without transverse internal septa; rarely winged or appendaged. 
Seeds albuminous flattened at right angles to or parallel with the 
valves, rarely rhomboid-subterete, transverse or rarely longitudinally 
disposed in the legume. Cotyledons plane or sinuous.—Trees, shrubs, 
or herbs. Leaves abruptly pinnate; common petiole frequently with 
sessile or stipitate glands, either solitary near the base or interpetiolu- 
lar. Stipules various. Flowers yellow or red, in axillary or terminal 
racemes, corymbs or fascicles ; occasionally solitary or geminate in the 
axils. 
A very large genus of warm and tropical countries, both of the New and Old World, 
especially abundant in the former. Of the following species, 13 are endemic, and 4 or 
5 appear to be introduced or commonly cultivated or perhaps naturalized. 
A. Sepals obtuse. Perfect stamens usually 7, of which 2-3 anterior are much larger, 
with elliptical or ovate anthers not exceeding 2-3 lines, dehiscing longitudinally. 
Legumes elongate, terete, or slightly compressed, indehiscent or rarely dehiscent, 
divided by transverse partitions into numerous 1-seeded cavities ; seeds horizontal, 
flattened at right angles to the axis of the legume. (§ Fistula, DC.) 
Bracts usually present at time of flowering.

Flowers in corymbs collected at the extremities. Outer sepals 
much smaller. Three anterior stamens longer. Seeds hori- 
zontal, flattened at right angles to the valves.

glands sessile. Stipules }-cordiform. Bracts from 
cordate-apiculate to ovate-cymbiform . . . . . . 6. C. Petersiana.
