Deciduous forests of the Western Peninsula, and Burma. Fl. April, May. 



The other climbing species of this genus may he classified as follows : — 



a. Underside of full-grown leaves densely clothed with silky, lustrous tomentum 

 (Western species). 



17. M. rubiginosa, Wight and Arn. ; Wight Ic. t. 207. Hills near Courtallum ; leaflets 

 2-3 pair, elliptic, 4-6 in. long ; secondary nerves 8-10 pair, petiolules §-J in., stipels

 Sitang valley, Upper Burma ; leaflets 2-3 pair, 4-10 in. long, long-caudate, acuminate, 

 finely but densely silky beneath, lower free portion of common petiole as long as, or 

 longer than leaflet, secondary nerves 6-9 pair, prominent beneath. Racemes slender, 12 

 in. long, fl. i in. long, standard densely silky on back; pod ultimately glabrous. 

 This is the species described by Kurz, P. Fl. i. 353, as Millettia sericea, Wight and 

 Arn., a large woody climber of the Malay peninsula and Java, leaflets lustrous silky 

 beneath; fl. J in. long. Pod velvety, turgid. 20. M. fruticosa, Benth. Nepal in Sal

 pair, prominent beneath. Fl. in erect racemes. Pod flat, linear velvety, 3—4 in. long. 

 Wunu, Burm., collected by Smales, Daungyu forest, Upper Burma, is similar, leaflets 

 obovate obtuse, densely silky beneath. 21. M. cana, Benth. Yenang3 r aung, on the 

 Irawaddi, Wallich, leaflets 3 pair, coriaceous, broadly elliptic, 2-3 in. long, 2 in. 

 broad, secondary nerves 6-8 pair, prominent. Pod woody, flat, lanceolate. 



c. Underside of full-grown leaves glabrous or nearly so. 



22. M. Piseidia, Wight Ic. t. 86, Khasi Hills, Assam, Upper Burma (Thinwin, Burm.), 

 Tonkin, glabrous, leaflets 2-3 pair, thinly coriaceous, elliptic-lanceolate, 3-4 in. long, 

 no stipels. Secondary nerves indistinct. Fl. f-1 in. long, white, on capillary pedicels.

23. M. monticola, Kurz F. Fl. i. 354, S"ikkim 6,000-7,000 ft., Assam, Nattaung, Burma 

 (6,500-7,200 ft., in stunted hill and pine forests); leaflets 4-5 pair, membranous, pale 

 beneath, from cuneate base oblong, shortly acuminate, 3-4 in. long, secondary nerves 

 6-8 pair not prominent, a minute network of reticulate veins between. Bacemes 

 compact, erect or spreading, unilateral before fl. open, generally several at the ends of 

 branches. Fl. (blue, Nattaung, Kurz), pale lilac or purple in Sikkim. Prain, I.e., 361, 

 463, states the pods are indehiscent and winged along both sutures, hence the species 

 would be Derris monticola. It is not D. secunda, Baker, Fl. Brit. Ind. ii. 247. 



24. M. caudata, Baker, Khasi hills, Silhet, glabrous, leaflets lanceolate, caudate-

 broad. 25. M. cserulea, Baker, Fl. Brit. Ind. ii. 107, found by Wallich at " Phanoc "
