1. D. triquetrum, BO. Prod. ii. 326. An erect perennial or under- 

 shrub, about 2 ft. high, nearly glabrous. Leaves consisting of a single leaflet, 

 varying from ovate-lanceolate to lanceolate-Unear, 2 to 4 in. long ; the petiole 

 flattened or winged, obovate or cuneate, with 2 stipeUse under the leaflet.

 subulate. Keel beaked. Pod sessile, flat, of several almost square articles,

Victoria Peak, Champion ; also Hance and Wright. I'requent in India and the Archipe-

 either glabrous ot nearly so, or sprinkled or edged with long hairs or thickly silky-hairy all 

 over. 



3. D. elegans, Benth. A branching perennial or undershrub. Stems 

 villous. Leaflets 3, ovate obtuse ; the terminal one about 8 or 4 in. long, the 

 lateral ones smaller, all villous above and very softly silky-viUous and whitish 

 underneath, the common petiole not dilated. Elowers small, in dense umbels 

 or heads, sessile along the branches of a terminal leafy panicle, and almost 

 enclosed in a 2-foliolate leaf-like bract at the base of each umbel, each leaflet 

 broadly ovate or orbicular, |- to i in. long and very oblique at the base. Pod 

 usually of 3 flat, nearly orbicular, smaE articles, very silky-viUous, both edges 

 of the pod, especially the lower one, indented between the articles. — Bicerma 

 elegans, DC. Prod. ii. 339. Fhyllodium elegans, Desv. j Benth. in PI. 

 Jungh. 217. 



Common in low grounds. Champion ; also Wright. Only known hitherto f.iom Java and 

 from S. China, and perhaps from Cochin China. 



3. D. pulchellum, Benth, A branching perennial or undershrub, like

 slightly pubescent on the upper surface, and softly pubescent not. vUlous un- 

 derneath, and the pod has almost universally only 2 articles, glabrous or 

 nearly so on the faces, and slightly ciliate at the edges only. — Bicerma pulchel- 

 lim, DC. Prod. ii. 339 ; Wight, Ic. t. 418. Fhyllodium pulehellum, Desv. ;
