in moderately dense racemes on flexuose peduncles Gin. or more long. Calyx £in. 
deep, the bifid upper lip a-third as long as the tube. Corolla pinkish or white, 
fragrant, twice the calyx or more. Pod short-stalked, 4 to 8 or 12in. long, 15 to 
18 lines broad, glabrescent, the prominent ribs \\ to 2 lines from the upper 
suture. Seeds red or white. — C. gladiata , DC. 1 . c . ; C. polystachya, Schweinf.;

Hab.: This African and East Indian bean has been met with as a stray from cultivation. 
60. PHASEOLUS, Linn. 
(Pods boat-shaped.) 
Calyx 2 upper lobes or teeth united in a short entire or 2-lobed upper lip, the 
lowest one longer and narrow. Standard broad, recurved, often oblique or 
twisted ; wings obliquely obovate or oblong, adhering to the keel ; keel produced 
into a long linear beak, more or less spirally twisted. Upper stamen free, the 
others united ; anthers uniform. Ovary nearly sessile, with several ovules ; 
style thickened within the beak of the keel and twisted with it, more or less 
bearded upwards along the inner side ; stigma oblique or on the inner side of the 
style. Pod linear or falcate, flat or terete, 2-valved. Seeds with a small or 
shortly linear hilum, not strophiolate. — Herbs either annual or perennial and 
woody at the base, short and erect or elongated and twining in the same species. 
Leaves pinnately 3-foliolate or very rarely 1-foliolate, stipellate, the leaflets entire 
or lobed. Stipules usually persistent, striate, sometimes produced below their 
insertion. Flowers white, yellowish, purple or red, in clusters of 2, 3 or more on 
lateral nodes in the upper portion of long axillary peduncles. Bracts and 
bracteoles usually very deciduous. 
A considerable genus, dispersed over the warmer regions of the New and the Old World. 
Several species long cultivated in various countries have given rise to many forms published as 
separate species, although frequently undistinguishable except by their origin. — Bentli. 
Stipules not produced below their insertion. Pod flattened. 
Bracteoles broad, striate, persistent, as long as the calyx. Flowers small, 
pale yellowish-white 1. P. vulgaris. 
Bracteoles small and very deciduous. Flowers large, pink or whitish with 
the wings purple 2. P. Truxillensix. 
Stipules oblong, produced below their insertion. Pod at length nearly 
cylindrical 3. P. Mungo. 
Shrubby, suberect, branches flexuose. Stipules conspicuous, lanceolate- 
setaceous. Calyx tubuloso-campanulate ; corolla purple and white. Pod 
nearly terete, 2 to 4in. long 4. P. semierectus.

257. Glabrous or silky-pubescent when young, dwarf and erect or tall and 
twining. Leaflets broad, acuminate, 2 to 3in. long or more, the stipollae small, 
obtuse. Stipules small, not produced below their insertion. Peduncles short, 
with few rather small pale yellow-green or whitish flowers. Bracteoles ovate, 
striate, as long as the calyx, and persistent. Calyx upper lobe very short, broad, 
obtuse and entire. Pod broadly linear, flattened, straight or slightly falcate. — 
Benth. in Mart. FI. Bras. Papil. 182, with the synonyms quoted. 
Hab.: Now and again met with as a stray from cultivation. 
The species is the most generally cultivated in all warm and temperate countries. Its origin 
is uncertain, probably Asiatic. — Bentli. 
2. P. Truxillensis (found at Truxille, Mexico), H. B. and K.; DC. Prod. 
ii. 391 ; Bentli. LI. Austr. ii. 257. Twining or trailing at the base, glabrous or 
more or less hairy, the hairs reflexed on the stem, appressed or silky on the 
leaves. Leaflets usually broadly ovate, obtuse or shortly acuminate, 2 to 4in. 
long, the terminal one somewhat rhomboid, the lateral ones very oblique, those of 
the upper leaves narrower, the stipellte small, oblong. Stipules small, not pro- 
duced below their insertion. Peduncles usually long, with few flowering nodes
