7-10 mm. long, brown when dry, sparingly ciliolate; stipels minute. Inflorescence 
racemose, as long or longer than the leaves, up to about eight-flowered ; peduncle finely 
prickly, especially towards the base; pedicels slender, up to 1 cm. long, with two small 
caducous bracteoles towards the apex ; bracts very early caducous. Flower-buds obliquely 
ellipsoid, obtusely contracted at the apex. Calyx broadly and slightly obliquely cam- 
panulate from a turbinate base, about 7 mm. long, with five broadly triangular mucronu- 
late lobes puberulous-ciliolate within the margin. Vezxillum yellow, finely mottled with 
brown, about 2-5 cm. long, rather shortly and broadly clawed, with two large obliquely 
lanceolate free appendages about 7 mm. long. Alae 2-5 cm. long, about 7 mm. broad. 
Carina 2 cm. long, the claw about as long as the more or less rhomboid limb. Stamnal 
sheath 2 cm. long, free parts of the filaments 6 mm. long. Ovary and style glabrous. 
Young fruits slightly torulose: mature ones not seen.

6. Sesbania grandiflora Poir. Encycl.. vii, 127 (1806); Pers. Syn., 1, 316 (1807). 
A small tree or shrub; branchlets rather thick, very shortly and softly pubescent 
when young. Leaves much longer than the inflorescence, up to about 20 cm. long; 
rachis subterete, slightly pubescent or glabrous; leaflets about 15-20 pairs, stalked, 
rather elongate-oblong, rounded and slightly unequal-sided at the base, rounded and 
minutely mucronate at the apex, about 2-5-3 cm. long and 0-5-1 em. broad, thinly 
chartaceous, shortly pubescent or glabrous, often glaucous, with about six pairs of lateral 
nerves; stipules deciduous ; stipels subulate, minute. Inflorescence few-flowered, axillary ; 
peduncle softly pubescent. Flowers large and showy, usually about 10 cm. long, pink 
or red. Fruits about 30 cm. long, flat. 
This well-marked species, the native country of which is doubtful, is widely cultivated 
in the tropics for its handsome flowers. The leaves are often used as a substitute for 
spinach. We have seen African specimens from Senegambia (Herb. Gay), Gold Coast 
(Axim, 7. F. Chipp, 391), and Lagos (Dr. J. W. Rowland).

obtuse, with a linear claw 5 mm. long, 2 mm. broad, and with a downward projecting 
tooth. Carina spotted, 2-2-5 cm. long, 0-75-1-1 cm. broad, obtuse, with a linear claw
