204 L. LEGUMINOS^. (J. G. Baker.) , [PTiaseolus. 



Closely allied to P. Mungo', and equally variable in general habit. Hairs of the 

 stem short, but spreading, not ferruginous. Stipules much smaller and narrower ; 

 leaflets membranous, subglabrous, 2-4 in. long, the end one broad-ovate, acute. 

 Flowers 10-20, the lower pedicels as long as the calyx, and the raceme finally 2-3 in. 

 long. Calyx in. ; teeth short, deltoid. Corolla \ in., yellow. Pod 2^-3 in. by 

 -| in., not so cylindrical as in P. Mungo, 8-1 2- seeded* glabrous from the"beginning, 

 considerably recurved. P. TOROSUS, Roxb. Fl. 2nd. iii. 298, is probably a cultivated 

 form, with short suberect stems and subsessile congested racemes. 



SUBGEN. 4. Dysolobium. Stipules small, basifixed, caducous, Pod 

 linear, subterete, densely velvety or bristly. Wings distinctly shorter than 

 the other petals. Keel prolonged into a long incurved beak but not forming 

 a complete spiral. Connects Phaseolus and Vigna. 



14. P. fuscus, Watt. PL As. Rar. 6, t. 6; Cat. 5613; stems slender 

 annual, leaflets ovate acute twice as long as broad softly downy, racemes short- 

 peduncled few-flowered lax, corolla middle-sized. Dunbaria" fusca, Kurz in 

 Journ. As. Soc. Seng, xliii. 2, 186. 



BIKMA ; Prome hills, Wallich. 



Stems firm, wide-twining, with many grooves. Leaflets membranous, dull green, 

 thinly pubescent above, grey -green, more densely downy beneath, always entire, rounded 

 at the base, narrowed gradually to a point, the end one 3-4 in. long. Peduncles 1-H 

 in. long. Racemes 2-3 in. long, copious, much shorter than the leaves ; pedicels 

 geminate,, spreading, -^-^ in. Calyx under 5- in., subglabrous, very gibbous, with a 

 few long deciduous bristles ; teeth ciliated, the lowest lanceolate, shorter than the 

 tube. Corolla |- in. ; standard ^ in. broad, yellowish with red-brown lines externally ; 

 keel and wings yellow. Pod linear, 2-3 in. by \-^ in., brown, clothed with spreading 

 brownish hairs, many- seeded. 



15. P. velutinus, Grah. in Wall. Cat. 5615; stems woody, leaflets 

 roundish cuspidate glabrescent above, racemes long-peduncled many-flowered, 

 corolla large. P. grandis, Wall. Cat. 5602, non Dalzell. Oanavalia grandis, 

 Kurz in Journ. As. Soc. Seng, xliii. 2, 185. 



EAST HIMALAYAS, tropical zone ; NIPAL, ASSAM, CHITTAGONG. AVA, MOTTLMEIN, 

 PEGU. 



A woody climber, with very large leaves and flowers, by far the most showy of all 

 the species. Stems terete, minutely pubescent. Leaflets thin, but flexible, full green, 

 subscabrous at first above, paler green beneath, with copious obscure bristly hairs, 

 broadly rounded at the base, 6-9 in. long. Racemes and woody terete peduncles 

 reaching each 6-9 in. long ; pedicels g \ in. ; bracteoles roundish, minute, adpressed 

 to the calyx. Calyx ^ in., finely silky ; lowest tooth lanceolate, shorter than of the 

 tube, the others much shorter still. Corolla reddish, more than twice as long as the 

 calyx ; standard 1 in. broad. Pod almost woody, subcylindrical, straight, ^-f ft. by 

 ^ in., deeply channelled down both sutures, densely brown-velvety. 



74. VIGNA, Savi. 



Twining herbs or shrubs, with exactly the habit of Phaseolus, from which 

 they differ by having the style and keel much less curved and lengthened .out. 

 Calyx campanulate ; teeth long or short, the upper often connate. Corolla much 

 exserted ; keel truncate or in Plectrotropis prolonged into an ascending or 

 slightly recurved beak. Stamens diadelphous ; anthers uniform. Ovary sessile, 

 many-ovuled ; style long, filiform, bearded along the inner face below the oblique 

 stigma. Pod linear, eubterete, subseptate. DISTRIB. Species 40-50, mostly
