 1. PiTHECOLOBiUM DULCE Benth. in Hook. Lond. Jomn. Bofc. Ill, 

 199. A tree 25-40 feet high with glabrous branches; stem 2 feet in 

 diara., the ultimate branclilets pendent, armed with stipular thorns. 

 Leaves evenly 2-pinnate, rachis 1 in. long glabrous, basal gland 0, with 

 a sessile small cupped-gland at its apex between the bases of the 1- 

 jugate pinnae, with secondary raohises '25 in. long also gland-beaiing 

 at apices between the bases of the 1-jugate leaflets glabrous on botli 

 surfaces, pale-green, approximated, oblique obovate-oblong, rigidly sub- 

 coriaceous, obtuse or occasionally subacute, 1-2 in. long, 'S-'T in. wide ; 

 stipules ascending, 2--.3 in. long, converted into conical smooth thorns, 

 the main and secondary rachises both shortly produced in acute points. 

 Floivcrs in dense heads •4--5 in. in diam., on puberulous pedicels '25 in. 

 long, solitary or 2-3 together in the axils of small lanceolate bracts 

 •1 in. long, along slender nodiform branchlets slightly zig-zag towards 

 their tips, glabrous or puberulous, striate, from 3-5 in. long, the bracts 

 of the lower two-thirds nccompanied by minute stipular spines, those 

 of the lowest fourth often replaced by reduced foliage leaves; the 

 branches arranged in terminal panicles 7-12 in. long, 5-8 in. wide, ex- 

 tending into the upper axils. Caly.v '05 in. long, grey-dowuy, subcam- 

 panulate, shortly toothed. Corolla white, '1 in. long, puberulous tube 

 wide-inf undibuliform, rather longer than the ovate-acute teetb. Fila- 

 inents united at base in a tube as long as that of the corolla, shortly 

 exserted. Ovary puberulous, shortly stipitate. Pod turgid, twisted, 

 dehiscent along the lower suture, both sutures slightly indented between 

 the seeds, 4-5 in. long, "5 in. wide; glabrous, wide-reticulated, the valves 

 coriaceous, claret-red when ripe. Seeds 6-8, obovate-oblong, -5 in. long, 

 •3 in. wide, '2 in. thick, testa smooth shining purplish, enveloped in a 

 firm edible pulpy pale avillus. Miq. Flor. Ind. Bat. I, 40; Bedd. Flor. 

 Sylvat. 1. 188 ; Bak. in Flor. Brit. Ind. II, 302. Mimosa dulcis Roxb.
