 specimens. Panicles ^-1 ft. long, -with very numerous ascending or spreading 

 branches, clothed with dense brown-silky pubescence, the upper ones growing 

 gradually shorter ; pedicels crowded, but not fascicled, much shorter than the calyx. 

 Calyx ^ in., thinly silky. Coj-oZte ■ whitish, 3-4 times the calyx. Fod 1-3-seeded, 

 1^-3 J m. by 1-1 J in., thin, flat, glabrous, finely-veined, each wing ^-^ in. broad. 



DOUBTFUL SPECIES, 



Of the following species of § Euderris the fruit is unknown. 



D. ACUMINATA, Bmth. PI. Jung. i. 252. (Pongamia elongata, Grah. in Wall. Cat. 

 S886, non 5915. P. acuminata, Grah. in Wall. Cat. 596l.) A large climber, with 

 glabrous branches and leaves. Leaflets 5-7, elongate-oblong, 4-6 in. long, with a 

 long very distinct cusp, green on both surfaces, -with the main veins raiseii below. 

 Bacemes 6-9 in. long, the flowers fascicled at the distant nodes, the rachis, pedicels 

 and calyx with a little brown pubescence ; pedicels ^-^ in., equalling or exceeding 

 the calyx. Corolla rose-red, | in. long. Ovary silky, 5-6-ovuled. — ^Nipal, Wallich ; 

 and a plant with 9-1 1 leaflets of similar shape, and shorter closer racemes of con- 

 siderably larger (f in. long) bright purple flowers in Sikkim, Hooh. fil. This last 

 closely resembles B. microptera, but the standard is not caUose. 



D. SECONDA, Baker. (Pongamia secunda, Grah. in Wall. Cat. 5890. Amerimnum 

 secundum, Hamilt. MSS.) Leaflets 7, oblong with a long cusp, 2-3 in. long, rigidly 

 coriaceous, glabrous rather shining above, the veins immersed. Bacemes like those of 

 B. scandens, but in a terminal panicle and in the axils of upper leaves ; rachis and 

 pedicels finely brown-silky, the latter densely fascicled, exceeding the calyx. Calyx 

 j5 in. Corolla reddish, f in., the blade of the standard oblong, not callose. Ovary 

 silky. — Assam, Hamilton. 



D. poiYSTACHTA, Benth. in Joum. Linn. Soc. iv. Stippl. 114. Branches and 

 leaves below glabrous. Leaflets 5-7, subeoriaceous, acuminate, pale green on both 

 surfaces, twice as long as broad, 3-4 in. long, with a distinct point. Bacemes long and 

 narrow, ^-1 ft. long, from the upper leaves and forming an end panicle, the nodes 

 copiously produced into branchlets, the rachises finely obscurely pubescent ; pedicels 

 exceeding the calyx, crowded on the branchlets. Calyx ^ in., slightly pubescent. 

 Corolla |-^ in., rose-red. Omry silky, with about 4 ovules. — Khasia, 2-4000 ft.. 

 Hook. fil. ^ Thomson. 



D. ovALiFOLiA, Benth. PI. Jungh, i. 252, ex parte. (Pongamia ovalifolia, W. ^ A. 

 Prodr. 262 ; Wight Ic. t. 328.) A climber, glabrous in all its parts, with general 

 habit and leaves very like Dalbergia volubilis. Leaflets 9, long-stalked, oblong, 

 obtuse, emarginate, 1^2 in. long, membranous, with raised veinlets. Bacemes 

 copious, axillary, ^ ft. long, sometimes geminate, with nodes produced and very 

 abundant small bright red flowers ; pedicels twice the calyx. Calyx ^ in., broadly 

 campanulate. Corolla J in. ; standard with a long claw and a broad blade, not 

 callose. Ovary slightly hairy, 2-ovuled. — Western Peninsdia, Wight. 



The following are probable species of § Dipteroderris, of which the flowers are 

 unknown. 



D. DISCOLOR, Benth. in Joum. Linn. Soc. iv. Swppl. 111. A robust climber, 

 glabrous throughout. Leaves long-petioled ; leaflets 6-9 obovate-oblong, 3-5 in. long, 

 obtusely pointed, bright green above, very glaucous below, rigidly coriaceous, with 

 immersed veins. Po<i oblong, 1 seeded, thicker than in the other species, lJ-1^ in. 

 by |-J in., both sutures raised and furnished with a narrow distinct wing. — Sikkim 

 and SiLHBT, Hook. fil. ^ Thomson, A diflferent type of the pod to the admitted 

 species, like that of Pongamia glabra in shape and texture, but with a double wing. 



D. WiQHTii, Baker: A slender glabrous climber. Leaflets 6-7, oblong, obtusely 

 pointed, broadly rounded at the base, 1-lJ in. long, rigidly subeoriaceous, with 

 immersed veins, pale grey-green on both surfaces. Backmes much exceeding the leaves.
