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

 filiform, twisted roimd vyith the keel, conspicuously hearded down the side 

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

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



Sttb&en. 1. Fhaseolus proper. Stifles smaE., basifixed. Pods ^-^ in. 

 broad, subcompressed. Keel prolonged into a complete spiral. 



1. P. lunatus, lAnn. ; DC. Prodr. ii. 393 ; twining, racemes lax short-

Everywhere cultivated, probably a native of America. — Distkib. 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. Sacemes reach ^ ft. long, the lower fascicles distant, with 

 2-4-flow6rs to a node ; pedicels finally ^— ^ in. long. Calyx JL in. ; teeth all very 

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

 INAMCENUS, Linn., Xtjaebsii, Zucc, pubebtjlus, H.B.K., and tunkinensis, Lour., are 

 cultivated varieties. 



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

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

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

 4-e-seeded. Poxb. Fl. Ind. iii. 287; W. ^ A. Prodr. 243, wore WaU. P.

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

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



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

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

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

 by iin., glabrous, rostrate, turgid.— The Scarlet Eunner, P. muitiflokus, WiM. ; DC. 

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

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