falcate, obtuse or subacute, glabrous or nearly so, venation obscure, 
2-3 lines long, about $ line broad. Spikes 2}—4 in. long, in axillary 
and terminal panicles usually exceeding the leaves; peduncles rusty- 
pubescent or puberulous, bracts 0 at flowering. Flowers whitish or 
Sateem heel about 2 lines long, ey pedicellate, pedicel articu- 
ated, the microscopic base persisting after the fall of the flower. Calyx 
cupuliform, 5-dentate. Petals linear-oval, acute. Stamens exserted, 
filaments filiform, consolidated at base with the disk and petals ; anther- 
gland large, caducous. Ovary glabrous, subsessile. Style at length as 
long as ovary. Legume 1 ft. long more or less, 1-14 in. broad, flat, 
straight, coriaceous, smooth, obscurely veined, continuous, the valves 
often cohering by the dorsal suture after dehiscence. Seed compressed 
with a membranous laterally dilated wing as broad as the valve.

Lower Guinea. Angola, Golungo Alto, Dr. Welwitsch! 
The description of the fruit is from Dr. Welwitsch’s specimens, which agree as to 
flower and foliage with the type-specimens from the Niger. 
2. P? Mannii, Oliv. A shrub attaining 15 ft. with terete, smooth, 
glabrous, dark, subglaucous branches. Leaves 6-9 in., glabrous ex- 
cepting the upper side of the rachis and under surface of the leaflets, 
which are thinly scattered with microscopic hairs ; pinne opposite 4—6- 
Jjugate ; leaflets subsessile, 8-13-jugate, elliptic-oblong, obtuse, slightly 
oblique at base, the midrib nearly central, $ in. long more or less, 2-3 
lines broad. Spikes 2-5 in. long, in panicles from the upper axils, 
Sometimes | ft. or more in length; rachis of the spike puberulous, rough 
with the minute persistent bases of the short pedicels of the fallen 
flowers. Bracts 0 at flowering. Flowers about 2 lines long, “ white.” 
Calyx-lobes short, deltoid. Petals oblong, rather acute. Stamens much 
exserted, filaments filiform, slightly thicker above the middle. Ovary 
glabrous, subsessile. Fruit not seen.

5. ADENANTHERA, Linn.; Benth. et Hook. f. Gen. Plant. i. 590. 
Flowers 5-merous, distinctly pedicellate. Calyx campanulate, 5- 
toothed. Petals valvate, coherent below or free. Stamens 10, free ; 
anthers with a deciduous apical gland; ‘‘pollen-grains 0.” Ovary 
sessile, multiovulate. Legume linear, compressed or turgid over the 
seeds, usually incurved or falcate, 2-valved; valves coriaceous, entire. 
Seeds thick, testa hard, smooth, scarlet or orange and_ black; 
embryo partially invested by a thin pellucid layer of albumen.—Un- 
armed trees. Veuves bipinnate; leaflets alternate or subopposite, 
numerous. Racemes often elongate, solitary or fascicled in the axils or 
panicled at the extremities. Flowers white or yellowish. 
A small genus of Tropical Asia, of which one species, with Jong curved or twisted 
egumes, the endocarp when dry pale straw-coloured with a satiny sheen and brilliantly 
scarlet seeds (A. pavonina, L.), has been introduced into the New World, and is doubt-
