slightly compressed, indehiscent, with a fragile tomentose exocarp and 
pulpy endocarp, 1- or 2-seeded. Embryo with flat, or nearly flat 
cotyledons in a horny albumen.—Unarmed trees. Leaves unequally 
pinnate with usually 3—7 leaflets; leaflets alternate or opposite, entire. 
Stipules minute very early deciduous. Flowers small in axillary and 
terminal panicles. Bracts minute, caducous. 
A small genus, common to the Tropics of both hemispheres. The following species 
are peculiar to Tropical Africa :— 
Leaflets usually 5-7. Panicles usually branched to a 3rd degree . 1. D. guineense. 
Leaflets usually 3. Tertiary panicle-branches obsolete or short . . 2. D. angolense. 
1. D. guineense, Willd. in Roem. Arch. i. 30. t. 6. Tree of mode- 
rate size. Leafy extremities rusty-pubescent or -puberulous ; leaflets 
coriaceous, usually 5 or 7, shortly petiolulate, varying from oval and 
ovate-lanceolate to elliptical or obovate-elliptical, apex narrowed to an 
obtuse or subacute point, or rounded and usually more or less obtusely 
apiculate, base more or less rounded or somewhat cuneate in the narrow- 
leaved forms, minutely pubescent on expansion but early glabrous and 
shining and finely reticulate above, pale or cinnamon-coloured (when 
dry) with or without minute appressed sparse pubescence and glandular 
papille beneath, 2-4 (5) in. long, ?-14 (4-2) in. broad; petiolule 
1-2} lines. Panicles many-flowered spreading terminal or fam the 
ba oe axils often much overtopping the leaves, with the buds rusty- 
puberulous or -pubescent. Flowers 3—5 lines in diameter. Fruit $—? in. 
in diameter, covered with a short velvety tomentum, 1- or 2-seeded ; 
the seeds embedded in a pleasantly acid pulp.—D. nitidum, Guill. et

This plant varies considerably in the form of the leaflets, and probably also in the 
size of the small flowers. A form in which the flowers are usually dipetalous, is the 
D., discolor, cited above. 
The fruit is the ‘“ Velvet Tamarind” of Sierra Leone. 
2. D. angolense, Welw. mss. A tree of 20-35 ft. or taller, with a 
trunk often 1-2 ft. in diameter; extremities tawny- or ferruginous- 
pubescent. Leaves almost invariably 5-foliolate ; leaflets very coriace- 
ous, on both surfaces closely and prominently reticulate, varying from 
ovate-lanceolate to elliptical, shortly broadly and obtusely acuminate, 
rounded or broadly cuneate at base, at length glabrous or sparsely 
and shortly hairy at least on the midrib beneath, 14—3 in. long, 3-14 
in. broad ; pubescent ance 1$—2 lines. Flowers numerous, yel- 
lowish, in terminal pubescent tomentose panicles, leafy below, less in- 
tricate than in D. guineense, branches of the panicle either simple 
racemes or the ultimate branchlets usually very short or obsolete. 
Pedicels 1-14 lines. Calyx spreading, 4—5 lines in diameter. Petals
