In all the provinces, on the sea-coasts and on nniddj tidal-river 

 banks, common. Distrib. Sea-shores from Eastern Africa and the Mas- 

 carene Islands to Malaya and Western Polynesia. 



Mr. Bentham would refer here Derris Forsteniana Bl. (Miq. Flor. Ind. Bat. I, 

 144) ; this hardly seems probable owing to Miquel's description of the leaves as 

 having 3 pairs of leaflets. Mr. Baker would also refer here Dalbergia heterophylla 

 Willd. {Sp. PL III, 901), but this again is very improbable for D. heterophylla has, 

 according to the original description, obtuse leaves, which Derris uliginosa never 

 has ; as, also, racemes longer than the leaves, which those of D. uliginosa never are. 



7. Dereis elegans Benth. PI. Jungh. I, 252. A rather slender 

 creeper sometimes 60 feet long, with brown pubescent branchlets. 

 Leaves 8-12 in. long, dark-green, leaflets 5 (very rarely 3 or 7) the 

 terminal exceeding the others, rigidly subcoriaceous, from oblong to 

 lanceolate, base always somewhat rounded, 3-8 in. long, 1*5-4 in. wide, 

 glabrous above, when young rusty-pubescent (sometimes persistently so) 

 beneath, rachis rusty-pubescent 4 in. long, petiolules glabrescent "2 in. 

 long with rigid subulate stipels '1 in. long, lateral veins 6-8 pairs pro- 

 minent like midrib beneath. Flowers in solitary or fascicled axillary 

 racemes 2-3 in. long, always much shorter than the leaves, nodes 

 bracteate tumid but not produced into stalks, each bearing one or several 

 subequal pedicels, rachis and pedicels rather densely villous with spread- 

 ing rusty pubescence, the pedicels filiform '35 in. long with 2 linear 

 bracteoles a little below the calyx. Calyx '15 in. long, black purple, 

 sparsely pubescent, margin subtruncate. Corolla pure-white with pink 

 tips, •4-*5 in. long, standard orbicular-oblong tapering at base eglandular. 

 Stamens monadelphous. Ovary softly villous. Ovules 2-4. Pod obliquely 

 rounded-oblong or oblong 1"5 (rarely 2*5 in.) long, 1 in. wide, thin, flat 

 distinctly reticulated, covered throughout with a fine sparse pubescence ; 

 seeds 1, rarely 2, much compressed '75 in. in diam. 



Var, typica ; leaflets ovate to lanceolate, acute, becoming at length 

 subglabrous beneath, flovvers "5 in. long. Derris elegans Benth. PI. Jungh. 

 I, 252; Journ. Lina. Soc. IV, Suppl. 109; Bak. in Flor. Brit, Ind. II,

Var. vestita ; leaflets oblong-acuminate to ovate-acute, densely 

 persistently rusty- velvety beneath, flovvers rather smaller '4 in. long.
