Stamens 10, free ; anthers elliptical or rotundate, versatile, dehiscing 

 longitudinally. Ovary sessile, 2-ovulate, ovules pendulous ; style 

 slender, stigma terminal, capitellate. Legume drupaceous, indehiscent, 

 thick, roundish, compressed, with strong" fibres traversing- the mesocarp, 

 a bony endocarp and crustaceous epicarp. Seed solitary, exalbuminous. 

 — Unarmed trees, glabrous or pubescent. Leaves abruptly pinnate, 

 though from the frequent alternation of the leaflets seeming impari- 

 pinnate at first sight, more or less translucently gland-dotted. Stipules 

 inconspicuous. Flowers paniculate, small, white or pale, fragrant. 

 Bracts and bracteoles minute, caducous. Fruit edible. 

 Confined to Tropical Asia. 



1. D. senegalense, Gmclin ; DC. Prod. ii. 521. Tree; extremities 

 pubescent or glabrous and more or less glaucous. Leaflets 6-12, alter- 

 nate or opposite, elliptic- or ovate-oblong, obtuse, entire or emarginate 

 at the apex, base, excepting sometimes in one or. two of the upper 

 leaflets, broadly rounded, broadly and obscurely undulate-crenate or 

 entire, glabrous or very thinly pubescent, sometimes glaucous beneath, 

 reticulate when dry, more or less coriaceous, variable in size, averaging 

 1J-2 in. in length in the typical (originally described) form, 2-3 (4-J) 

 in. in others ; petiolules 1 J- 2 lines. Flowers small, in axillary fasci- 

 cled or solitary panicles, often from the nodes of fallen leaves or scales, 

 1 or 2-6 in. in length, each with a distinct rachis giving off alternate 

 lateral racemes or spikes. Bracts minute^ concave, very early de- 

 ciduous. Pedicels very short or 0. Sepals 2-2J lines long, pilose or 

 nearly glabrous within. Fruit usually nearly round, compressed, 

 1J-2J in. in diameter, 1-1 \ in. in thickness ; epicarp thinly crusta- 

 ceous when dry, smooth or nearly so, the pulpy edible mesocarp is 

 traversed by numerous fibrous processes from the surface of the bony 

 endocarp. Seed compressed, about 1 in. in diameter. — Fl. Senegambiae, 

 i. 269, t. 59. — D. microcarpum, Guill. et Perr. Fl. Seneg. i. 271 ; D. 

 lleudelotianum, Baill. in Adans. vi. 201. 



Upper Guinea, a. Leaflets usually 8-12, 1J-2J in. long, rachis often thinly 

 pilose. Panicles usually below the leaves. Flowers subsessile ; connective of the 

 anthers (at least sometimes) minutely apiculate. Senegambia, Perrottet ! Gambia, 

 Heuddot ! 



p. Leaflets about 8, 2-3 or even 5 in. long, glabrous and glaucous. Panicles glaucous 

 or pnlverulent-glaucous ; flowers shortly pedicellate ; anthers muticous. Niger,

The Upper Guinea forms a and /S may prove specifically different, but there exist 

 intermediates (Senegambia, Heudelot, No. 571) which hardly justify their separation at 

 present. The tree is described both by Guillemin and Perrottet and by Barter to be a 

 small one (15-25 ft.), but the Governor of the Gambia sends to the Kew Museum sec- 

 tions of the trunk 2 ft. or 2 ft. 6 in. in diameter.
