terior, 2 lateral), oblong or obovate- oblong-, subequal, equal to or but 

 slightly exceeding* the calyx, narrowed to the base or shortly clawed ; 

 2 anterior petals minute, subulate or squamiform. Fertile stamens 3, 

 anterior connate nearly half their length, alternating- with minute or 

 rudimentary staminodia ; anthers oblong', versatile. Ovary stipitate ; 

 style rather stout equalling- the stamens ; stigma terminal, obtuse, 

 slightly thickened; ovules 8-10 or more. Legume oblong or linear- 

 oblong, curved, or nearly straight, subterete, or compressed ; outer 

 layer of pericarp thin, crustaceous ; inner pulpy traversed by fibres. 

 Seeds obovate-elliptical or roundish, compressed, with a thick, shining 

 testa, each side marked with a large faintly defined areole ; albumen 0. 

 — Large unarmed forest- tree. Leaves abruptly pinnate, leaflets small, 

 coriaceous, oblong, obtuse, reticulate, subsessile, multi-jugate, usually 

 in 9-17-21 pairs. Stipules linear, early caducous. Flowers yellowish 

 or red-striped in simple or panicled racemes, terminal or lateral ; 

 bracts concave- caducous ; bracteoles valvate enclosing the early bud, 

 caducous. 



The Tamarind, the only species of the genus, valued on account of the acid pulp of 

 the fruit, would appear to be truly indigenous in Tropical Africa. It is widely diffused, 

 however, either under cultivation or naturalized, through the Tropics of both the New 

 and Old World.

Dr. Welwitsch collected in Golungo' Alto, in a locality where perhaps the Tamarind 

 had been formerly cultivated, specimens of a remarkable monstrosity of this species, the 

 leaflets being reduced to thtir midrib, excepting a short expansion of the lamina on the 

 lower side at the base. As pointed out to me by Dr. Welwitsch, the seeds appear to be 

 singly enclosed in an arilliform envelope, thinly crustaceous when dry, probably derived 

 from the pulpy endocarp.

Calyx-tube turbinate ; segments linear or oblong elongate, thick, 

 with narrow imbricating abruptly thinner margins. Petals 5, much 

 exceeding the calyx, subequal in length, broadly oblanceolate or 

 obovate-spathulate, narrowed gradually into the long-winged claw, 

 traversed longitudinally by a stout at length evanescent midrib. Sta- 

 mens 10, upper free, rest connate below ; filaments elongate, alter- 

 nately silky-pilose below; anthers linear-oblong, versatile, each end
