242 1. LEGUMTNOSiE. (J. G. Baker.) [Derris. 



Eastern Himalayas, "Western Peninsula and Ceylon.— Disteib, China, N, 

 Australia, Polynesia, Madagascar, ZaniLesi-land. 



A mde-climbing shrub, with branchlets and leaves quite glabrous from an early 

 stage, Zeavfs distinctly petioled, ^-^ ft. long ; leaflets usually 5, distinctly stalked, 

 narrowed to a point, 2-4 in. long, the lowest pair shorter, ovate, the veins not promi- 

 nent on either surface. Racemes short-peduncled, 2-4 in. long, the lower nodes often 

 produced into short branches ; pedicels fascicled, as long as the calyx. Calyx cam- 

 panulate, ^^ in., subglabrous; teeth obscure. Corolla rose-red, | in. long; blade of 

 standard round, not callose. Pod sessile, glabrous, 1-2-seeded, obliquely roundish or 

 oblong, 1-1^ in. by 1 in., thin, flat, prominently veined, with a distinct narrow wing to 

 the upper suture. — A plant gathered at Malacca by Griffith differs by its thicker and 

 more rigid leaves and longer pedicels. It is referred by Bentham to D. trifoliata, 

 Lour. FL Cochin, 433 (D. affinis, Beiith. PL Jungh. i. 252), but the pod is unknown. 



6. D. vestlta, 5fifZ;er ; brauclies clotbed with dense brown pubescence, 

 leaflets 5 large obovate-oblong rigidly coriaceous, flowers middle-sized in ses- 

 sile congested axillary racemes. 



Malacca, Maingay. 



A climber, with the branches and under surface of the leaves densely covered witn 

 soft short brown pubescence. Leaflets 3-6 in. long, glabrous and rather glossy above, 

 rather rounded at the base, pointed, with conspicuous main veins raised on the under- 

 surface. Panicles 1-2 in. long, sometimes fascicled ; pedicels equalling or rather exceed- 

 ing the calyx. Calyx ^^ in., finely pubescent ; teeth obscure. Corolla red, | in. long ; 

 standard with a round not callose blade. Pod just like that of D, uliginosa in texture, 

 veining and shape, but thinly clothed with fine brown pubescence. 



7. D. elegrans, Bmth. PI Jungh. I 252 ; branches clothed with fine 

 brown pubescence, leaflets 5-7 large obovate-oblono: subcoria<;eous, flowers large 

 in short sessile axillary racemes. Benth. in Journ. Linn, Soc. iv. Suppl. 109. Fon- 

 gamia elegans and V. floribunda^ Grah. in Wall Cat. 6883, 6884. , 



Biema; Phanoe and Trogla hills, Wallich. Tbnasseeim, Griffith. 



Leaves, including the petiole, a foot long, thin but subcoriaceous, thinly clothed be- 

 neath with evanescent fine brown pubescence ; leaflets narrowed to a subobtuse point, 

 rounded at the base, the end one 6-8 in. long. Racemes dense or sublax, 2-4 in. lpnff» 

 clothed with fine brown pubescence on the rachis and pedicels ; pedicels |-J ^°'1,*>,^ 

 lower nodes sometimes produced. Calyx under ^ in., broadly campanulate; ^^^ j.*^ ' 

 scure. Corolla bright red, ^ in. long ; blade of standard round, not callose. Pod]^^ 

 like that of D. vestita. ^

8. D. paniculata, Benth. in Journ. Linn. Soc. iv. Suppl 105; branchlets 

 clothed with fine very short brown pubescence, leaflets 5-7 middle-sized ^^^^^ 

 oblong rigidly coriaceous, flowers very small in copious peduncled elongatea 

 panicles. Brachypterum Benthami, thwaites Enum. 93. 



Ceylon, Walker, Thwaites, 



Branches slender, terete, soon glabrescent. Leaflets subacute, rounded at the base, 

 thick and rigid in texture, 2-4 in. long, not prominently veined, glabrescent ^^"^ j 

 early stage. Panic/es copious, reaching a foot long, with numerous slender cur ^ 



branches, clothed with finely silky brown pubescence; pedicels ^^ in. ^^^^^ j]^l^ 

 between tubular and campanulate, brown-silky, with short obscure teeth, Cor^f'^^ ^ ' 

 scarcely \ in. long. Pod 1-2-seeded, 1-2 in. by | in., rigid in texture, turgi<i ^c^' 

 the seeds, persistently brown-silky, not veined, with a wing under ^ in. broad 

 the upper suture. 



ft Leaflets many. Standard with two callosities at the base of the I*
