banks of botli peninsulas and the Andamanb. Fl. CS. AlbO on the coasts of Ceylon, 

 and from Eastern Africa to AVestern Polynebia. The twibted stems used for cattle 

 ropes. Nearly allied : 5. D, elegans, Benth. Andamanb, Burma, Siam, Malay Peninsula,

 thin f errugineous hairs, leafietb 2 pair, coriaceous, 8-8 in. long, stipels small, subulate, 

 hairy. Fl. nearly J in. long, petals white with iiink tips. Pod broad, generally 1-seeded. 



The other climbers of this genus nmj be classijfied as follows : — 

 A. Pod winged on the upper suture only. 



6. D. sinuata, Thwaites ; Kurz, F. Fl, i. 340. Vern. Myauk-gon-nyin, Burm. Sea- 

 coast of Bengal, Burma, Ceylon, Malay Peninsula and Archipelago. Leaflets 2-3 pair, 

 glabrous, rigidly coriaceous, broad-orate, 4-3 in. long, 2-3 in. wide. FL | in., in ample 

 thyrsoid panicles. Pod coriaceous, turgid, 2-8 in. long, 1-5-seeded, contracted between 

 seeds, 7, D. elHptica, Benth.— Syn. Poiujamia elHptica, Wall. PL As. Ear. t. 237 ; "Wight 

 Ic. t. 420, Chittagong to Tenasserim, Malay Peninsula, Sumatra, Java. Young shoots, 

 petioles, and inflorescence rusty-tomentose, leaflets 4-6 pair, 3-6 ixi. long. FL ^ in. on 

 few fld. pedunculate corymbs in axillary racemes, standard densely silky on back. 

 Pod flat, thin, 2-3 in. long, sutures raised, the upper with a narrow wing. Similar in 

 appearance to MlUefta pach,ijcarpa, Benth., differs by the pod and the silky standard. 

 8. D. olDlonga, Benth. ; Trimen Handb. p. 9B, tab. 29. West coast, from the Konkan south- 

 wards, Ceylon. G-labrous, leaflets 4-6 pair, ohartaceous, oblong-lanceolate or oblanceo- 

 late, 2-3 in. long, " a ver^^ ornamental climber, the white or pink fl. on short racemose 

 panicles appearing w4th the young leaves, which are of the same coppery pink colour 

 as the calyx " Trimen, 9. D. cuaeifolia, Benth.— Syn. JX discolor^ Benth. Outer Hima- 

 laya from Nepal eastward, ascending to 6,000 ft., Madhupur jungle, Maimansingh. 

 Chittagong, Burma. Nearly glabrous, leaflets 3-5 pair, 3-5 in. loug, pale beneath 

 while young, with minute silky hairs chiefly beneath, ehartaceous, elliptic lanceolate 

 or oblanceolate, acute. Fl. bright red J in. long, in 2-6 fld. pedunculate umbels, on 

 short corymbiform or racemiform axillary panicles. Pods coriaceous, 1-2-seeded, 1-2 

 in, long, 1 in. broad, often a narrow wing on the lower suture. From this Prain, I.e., 

 459 separates D. inalaecemi^^ Prain, Moulmein, Malay Peninsula, with fewer but 

 larger subcoriaceons leaflets, which are abruptly long acuminate. 10. D. microptera, 

 Benth., is nearly allied to No. 9, but leaflets 2-4 pair, perfectly glabrous from the 

 beginning, caudate-acuminate, a network of minute, very regu.lar but not raised 

 reticulate veins between tertiary nerves. FL I in. long, fasciculate on tumid not nmch 

 produced nodes in lax drooping slender racemes 12 in. long. Pod thin, with a narrow 

 wing on the seminal suture. (Prain, I.e. 460, describes the pod as dehiscent, con- 

 sequently it should be i)laced under Milletfia.) 



B. Pod winged on both sxitures, leaves glabrous, Western species. 



11. D. eualata, Bedd. Ic, PL Ind. Or. 1. 186, common in the plains of South Kanara and 

 Malabar. Coorg, Nilgiris, Anamalais. Leaflets 3-4 pair, 2-3 in. long, fl. white, J in. 

 long, in ample rusty tomentose panicles. Pod glabrous, 4-5 in. long. 12. D. "brevipes, 

 Baker, Western Ghats from the Ivonkan to the Nilgiris. Leaflets coriaceous, 3 pair, 

 2-3 in., fl. J in. long, in ample rusty-tomentose panicles, which generally are fascicu- 

 late at the ends of branches. Pod brown-silky, 1-2-seeded, 1-2 in. long. JD. Wightii, 

 Baker, and D. ovalifolia^ Benth., probably belong to this species. 13. D. Heyneana, 

 Benth. Western Ghats from North Kanara southwards. Leaflets coriaceous broadly 

 elliptic, 2 pair, 2-3 in. long. FL on capillary pedicels in ample drooping panicles, 

 with slender branches. Pod glossy, veined, 1-3-seeded, 2-4 in, long, wings broad. 14. 

 D. platyptera, Baker. Plains and Ghats on the west coast, from North Kanara south- 

 wards. Leaflets 2-3 pair, rigidly coriaceous, brown when dry, shining above, pale 

 beneath. FL on short racemes, in long, drooping, rusty-tomentose, i-acemiform panicles. 

 Pod fiatj glossy, veined, 3-5 in. long, wings broad. Stamens diadelphous (Cooke) and 

 otherwise similar to 16, with which it may have to be u.nited. 



C. Pod winged on both sutures, Eastern species. 



15. B. femiginea, Benth. Dwars, Assam, Silhet, Cachar. Burma. Branchlets, inflor- 

 escence and underside of leaves rusty-tomentose, fl. white, fasciculate on slender pedicels, 

 longer than calyx, in long drooping panicled racemes. Pod velvety while young, 2-3 

 in. long. 16, D. tliyrsrflora, Benth, Assam, Khasi hills, Cachar, Andamans, Tenasserim. 

 Also Malay Peninsula, Sumatra, Java, Borneo. Leaflets 2^ pair, coriaceous, glabrous, 

 as in all the following species. FL white on short pedicels, single, not fascicled, in ample 

 erect thyrsoid rusty pubescent panicles ; vexillary stamen free. Pod thin, glabrous, 

 veined, 2-4 in. long, wings broad. Prain, in Journ, As. Soc. Beng., vol. 66 (1898), 99, 

 462, restricts this to the Malay Peninsula and Archipelago, while he includes the 

 northern specimens from Assam to the Andamans under a new species, D. WaUicJiii, fl.
