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. Peduncles 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.
