style simple, terminal. Ovules solitary. Fruit a drupe, 1 -seeded, with a bonv 

 or crustaceous putamen. Seed " exalbuminous ; embryo with thick plntio'- 

 convex, corrugate or 2-lobed cotyledons and a superior radicle." — Shrubs or 

 small trees, usually armed, at least when young or stunted, with axillary or 

 supra-axillary spines. Leaves 2.foliolate ; leaflets entire, coriaceous. Flowers 

 greenish, in axillary fascicles or short racemose cymes. 



A genus of two or three species, confined to the warmer parts of Africa and .\8ia. 



1. B. segyptiaca, Belile ; DC. Prod. i. 708. Extreraitieu terete, mi- 

 nutely hoary-puberulous or glabrate ; spines various, usually about ^-1 in., 

 sometimes 3 in., often wanting on fully grown trees, straight, ascending or 

 patent. Leaflets elliptical or varying from ovate- to obovatc-elliptical or 

 rotundate, obtuse or broadly pointed, \-\\ in. long, shortly |)etiolulate ; pe- 

 tiole usually much shorter than the leaflets. Ovary soon lengthening out 

 after flowering, narrowed into the style. Drupe edible, with^i thick bony 

 putamen ; - the seed afi'ording an oil. 



Upper Ouinea. Niger, Barter ! 



North Central. Bornou (fide Browji in Denh. and Clapp. App. 232). 



Nile Iiand. Upper Nile, Abyssinia, Sennar, Schimper ! Roth ! Kotschy ! and other*. 



Var. anffolensis,Vfelw. inss. Fruit ellipsoidal, terete, about 1 iu. long, with a thin crui- 

 taceous endocarp. 



Lioiver Gruinea. Loanda, Angola, Dr. Weltoitsch I 



The fruit of this variety differs so remarkably from that of the ordinary form, that thu 

 plant raay probably be specifically distinct. I do not detect any difference, however, in the 

 flower. 



A fragment in the Kew Herbarium, from the Rovuma river {T)r. Kiri), without flowers, 

 bears forked spines. It may belong to a distinct species. It is described as a cUmbing shrub.

TkIBE OCHNEJi. 



Flowers regular, hermaphrodite. Sepals 5, free, imbricate, scarious or 

 coriaceous. Petals as many, free, equalling or exceeding the sepals, sub- 

 sessile or unguiculate, contorted or imbricate. Stamens 10 or indefinite; 

 filaments frequently persistent, free. Anthers linear, often elongate or ob- 

 long, basifixed, dehiscing longitudinally or by apical pores. Ovary deeply 

 3-10-lobed, inserted upon a thickened disk enlarging after flowering, each 

 lobe 1-celled, 1 -ovulate ; style central, filiform or subulate ; stigma terminal, 

 simple, or style divided at the apex into as many short branches as carj)els ; 

 stigmas capitellate. Fruit of 3-10 drupes inserted upon the enlarged 

 torus, sessile. Seeds exalbuminmis ; radicle very small. — Trees or shrubs. 

 Leaves alternate, simple, perfectly glabrous, pennivcined, stipulate. Flowers

Ochnacece are a small Order, confined to the tropics, most of the genera being [MTuhar to 

 the New World. The two following genera are shared with both .\bia and America.
