200 L. LEGUMINOS.E. (J. G. Baker.) - [Phaseolus. 



' 73. PHASEOLUS, Linn. 



Twiners, usually herbaceous, with 3-foliolate stipellate leaves. Flowers in 

 copious axillary racemes ; bracteoles usually conspicuous and persistent. Calyx 

 campanulate, the lowest tooth usually longer than the rest and the two upper- 

 most subconnate. Corolla much exserted, the keel prolonged into a very long 

 beak which forms a complete, or in Dysolobium, nearly complete, spiral. 

 Stamens diadelphous ; anthers uniform. Ovary sessile, many-ovuled ; style 

 filiform, twisted round with the keel, conspicuously bearded down the side 

 below the very oblique stigma. Pod linear, rarely oblong, subterete or sub- 

 compressed, more or less distinctly septate between the seeds. DISTRIB. Species 

 about 60, mostly tropical, many widely cultivated, especially in America. 



STTBGEN. 1. Phaseolus proper. Stipules small, basifixed. Pot/s^-fin. 

 broad, subcompressed. Keel prolonged into a complete spiral. 



1. P, iunatus, 'Linn. ; DC. Prodr. ii. 393 ; twining, racemes lax short- 

 peduncled many-flowered, pedicels longer than the calyx, corolla small greenish- 

 yellow, bracteoles minute, pod recurved oblong 2-4-seeded. Roxb. Fl. Ind. iii. 

 287 ; W. $ A. Prodr. 244. P. vulgaris, Wall. Cat. 5595, non Linn. 



Everywhere cultivated, probably a native of America. DISTRIB. Everywhere in 

 the tropics. 



A tall biennial, with stems at first minutely downy, soon glabrescent, easily dis- 

 tinguished from all the other species by the shape of the pod, which is 2-3 in. by 

 f-f in., less turgid than in any of the others, with the upper suture recurved and the 

 lower broadly rounded. Racemes reach ^ ft. long, the lower fascicles distant, with 

 2-4-flowers to a node ; pedicels finally 53- in. long. Calyx ^ in. ; teeth all very 

 short. Corolla 3-4 times the calyx. Seeds large, very variable in colour. P. 

 INAMCENUS, Linn., XUAKESII, Zucc., PTJBERULUS, H.B.K., and TUNKINENSIS, Lour., are 

 cultivated varieties. 



2. P. vulgaris, Linn. ; DC. Prodr. ii. 392; suberect or twining, racemes 

 lax subsessile few-flowered, pedicels longer than the calyx, corolla middle-sized 

 white or lilac-purple, bracteoles often exceeding the calyx, pods linear recurved 

 4-6-seeded. Roxb. Fl. Ind. iii. 287 ; W. $ A. Prodr. 243, non Wall. P. 

 nanus, Linn. ; DC. ; Roxb. ; W. fy A. loo. cit. P. compressus, oblongus, sapo- 

 naceus, tumidus, hsematocarpus, spheericus and gonospermus, DC. loc. cit. 



Universally cultivated, but not anywhere clearly known as a wild plant. 

 DISTRIB. Spread everywhere, both in tropical and temperate regions. 



A subglabrous annual. Stems low and suberect (P. NANUS, Linn.) or twining to a 

 height of 6-10 ft. (P. VULGARIS, Linn.). Racemes much shorter than the leaves; 

 pedicels finally ^-5- in. long ; bracteoles ovate or roundish, persistent. Pod 4-6 in. 

 by ^ in., glabrous, rostrate, turgid. The Scarlet Kunner, P. MULTIFIXDRTJS, Willd. ; DC. 

 Prodr. ii. 392 ; W. $ A. Prodr. 244 ; P. COCCINEUS, Lam., differs by its bright scarlet 

 casually white flowers, arranged in long racemes which often overtop the leaves. 



3. P. adenanthus, G. F. Meyer, Prim. Fl. Esseq. 239 ; twining, racemes 

 dense capitate, pedicels very short, corolla large red, pod linear recurved manv- 

 seeded. P. rostratus, Wall. PI. As. Rar. t. 63; Wall. Cat. 5610; W. $ A. 

 Prodr. 244; Wight Ic. t. 34. P. alatus, Roxb. Hort. Seng. 54; Fl. Ind. iii.
