8. Ormosia venosa Bak. in Flor. Brit. Ind. II, 254 A tall tree, 

 with branches densely persistently velvety-pubescent. Leaves 4-6 in. 

 long, leaflets 7, obovate-oblong, obtuse or subobtuse, base cuneate nearly 

 sessile on the rachis, rigidly coriaceous, greyish-green glabrous but dull 

 above, densely persistently tomentose beneath, 3-4 in. long 1*5-2 in. 

 across, terminal exceeding the rest, secondary nerves 10-12, distinctly 

 raised beneath, rachis densely velvety. Racemes terminal crowded, with, 

 rather slender branches, 3-4 in. long and about as wide, rachis and 

 branches densely velvety ; pedicels '2 in. long, nearly equalling the calyx, 

 bracts '15 in. long, lanceolate, persistent, bracteoles at base of pedicels *l s 

 in. long, 2 bracteoles under calyx minute but subpersistent. Calyx "25 

 in. long, densely velvety, teeth triangular, three lower as long as tube," 

 two upper subconnate. Corolla '35 in. long, apparently white, standard 

 *3 in. across. Stamens incurved, exserted. Ovary velvety. Pod obtuse 

 or subacute, orbicular or oblong, obtuse or subacute, 1*5 in. long, 1/35 in. 

 across, '1 in. thick, the valves very thickly woody, black and glabrous 

 externally. Seeds usually solitary, ovoid, "5 in. long, *4 in. wide, crim- 

 son-red, without arillus.

 A very distinct species. 



Suborder II. Cjesalpinieje. 



Trees or shrubs, very rarely herbs. Leaves pinnate or 2-pinnate 

 leaflets 1-co -paired, rarely simple or 1-foliolate, stipels usually 0, if 

 present very minute. Inflorescence racemose, rarely cymose, very rarely 

 spicate ; axillary, lateral, or in terminal panicles. Flowers irregular or 

 very rarely regular, 5-, less often 4-merous. Sepals 5, or 4 from fusion of 

 the upper two, divided to the summit of the disc that lines the short or 

 long calyx-tube, imbricate or rarely valvate, or very rarely united in a 

 toothed or lobed limb. Petals 5, or fewer by abortion, the upper inner- 

 most in bud, the others variously imbricate. Stamens 10, or fewer by 

 abortion, very rarely indefinite, free or rarely some or all more or less 

 connate; anthers various. Ovary free or united by its stipe to the disc- 

 bearing calyx- tube. Seeds various, albumen copious, scanty, or 0. 

 Radicle straight or slightly oblique, hidden between cotyledons, or short- 

 ly exserted.
