Upper Guinea. Bonny river, Mann! 
Widely spread in the West Indies, and opposite shores of the mainland. 
16. ALBIZZIA, Durazz.; Benth. et Hook. f. Gen. Plant. i. 596. 
Flowers capitate (in African species), sessile, or shortly pedicellate, 
usually 5-merous. Calyx tubular to campanulate, toothed. Petals 
5—4, united $ their length or more, valvate. Stamens indefinite, ex- 
serted ; filaments united at the base only or in a long exserted sheath 
(§ Zygia); anthers minute, “ pollen cohering in 3-4 masses in each cell.” 
Legume straight, flat, oblong or broadly linear, indehiscent or 2-valved, 
valves usually thin, continuous or sinuous from abortion of seeds. Seeds 
compressed, usually subdistant.—Trees or shrubs, unarmed. Leaves 
bipinnate ; leaflets various; rachis frequently with 1 or more sessile 
glands. Stipules rarely conspicuous. yee axillary, solitary or 
usually fascicled towards the extremities. Stamens elongate. 
A considerable genus of the Old World. With two or three exceptions the following 
species appear to be peculiar to Africa. The clavis to the species here given must be 
used with caution. Several species which appear distinct do not afford much contrast 
in brief diagnoses.
