glabrous, longer than anthers, and a linear-oblong samara, rounded at both ends; 

 yields a resin, matti pal, used in medicine and as incense (Pharm. Ind. 50).

Thorns axillary, strong, very sharp, often long, leaf- and flower-bearing ; 

 young parts pubescent, in dry localities hoary-tomentose. Leaflets lanceo- 

 late, oblong or obovate, nearly sessile, on a common petiole less than \ 

 length of leaflets. Flowers small, white, or greenish white, fragrant, 

 crowded in fascicles, axillary and along lateral branches. Sepals oval, 

 downy, nearly as long as petals, both spreading, reflexed, and eventually 

 deciduous. Style erect, short ; stigma slightly 5-lobed. Drupe ovoid, 2 

 in. long, 5-grooved, covered with a light-grey dry rind, enclosing a bitter 

 pulp with an offensive greasy smell ; nut exoeediigly hard, tubercled out- 

 side, 1-seeded. 



Common in many parts of India, as far north as Delhi ; in Rajputana, 

 Bandelkhand, theCentral Provinces, the Northern Circars,theDekkan, and South 

 India ; grows chiefly in open dry places and on stiff clay soU. New leaves in 

 March. Fl. in April and Ma,y. Usually a scraggy shrub, in favourable condi- 

 tions a small tree, 30 ft. high, with an erect, short trunk, 2 ft. and more in girth. 

 The roots spread far, and throw up suckers at a considerable distance from the 

 trunk. Bark of trunk smooth, yellow or cinereous. Wood chiefly used for fuel. 

 From the seed a fixed oil is pressed ; the pulp is used to clean silk in Eajputana ; 

 the seeds, the bitter bark, and subacid leaves are employed in native medicine; 

 the hard kernel of the fruit (filled with gunpowder) is used in fireworks. 



The second species of this genus, B. cegyptiaca, DeKle, — Boissier Fl. Orient, 

 i. 944, Oliver Flora Trop. Afr. i. 315 ; Palestine, Egypt, Arabia, and tropical 

 Africa, — has longer petioles, and the ovary lengthens- out considerably after 

 flowering. In the Indian plant the ovary swells, but remains ovoid and short. 

 It is, however, a matter for further inquiry, whether all Indian forms belong to 

 one species. 



3. PICRASMA, Blume. 



Trees, aU parts very bitter, with alternate imparipinnate leaves. 

 Flowers unisexual, in corymbose panicles. Calyx small, 4-5-dentate. 

 Petals 4-5, ovate, valvate. Male flowers with 4-5 stamens, inserted under 

 the disc. Carpels 3-5, distinct, on a thick disc ; ovules solitary. Fruit 

 consisting of 1-3, nearly dry, drupes ; seeds with a straight embryo in a 

 .fleshy albumen.
