This species is distinguished especially by its very small flowers and slender 
inflorescences. S. sericea D.C. from Ceylon is a very closely allied species, with fruits 
usually broader than those of S. pubescens. | 
11. Sesbania Dalzielii * n. sp. é 
A slender shrub up to 2 m. high; branches weak, angular when young, slightly 
pubescent, at length striate. Leaves usually longer than the inflorescence, 15-25 cm. 
long; rhachis and leaflets silky pubescent ; leaflets up to 40 pairs, shortly stalked, linear- 
oblong, rounded and acutely mucronate at the apex, obliquely acute at the base, 0 -8—2 -5 cm. 
long, 2-3-5 mm. broad, coriaceous, appressed silky-pubescent on both surfaces ; stipules 
linear-subulate, acute, very soon falling off; stipels very minute. Inflorescence slender 
and laxly flowered; the uppermost ones longer than their subtending leaves; peduncle 
pubescent towards the base; pedicels slender, glabrous, bibracteolate towards the apex ; 
bracteoles linear, 2 mm. long, falling off before the flower opens. Flower-buds ellipsoid- 
turbinate, shortly acuminate, glabrous. Calyx campanulate, acutely turbinate at the 
base, 5 mm. long, glabrous outside, ciliate within the five acutely acuminate lobes. 
Vezsllum with two small sessile appendages on the claw. Ovary glabrous. Fruit about 
20 em. long, strongly torulose, shortly and acutely beaked, about 25-seeded. Seeds oblong- 
ellipsoid, 5 mm. long, green and shining.

12. Sesbania Wildemannii, nom. nov. 
Sesbama affinis De Wild, in Ann. Mus. Cong; Ser. V, 1, 141 (1904), non Schrad. 
Stems terete, finely longitudinally grooved, glabrous. Leaves up to about 9 cm. long ; 
thachis angular, shortly pubescent; leaflets about 20-25 pairs, linear-oblong, rounded

2 mm. broad, grey, at length glabrous above, finely appressed-pubescent below ; stipules 
small, deciduous. Inflorescence few-flowered, very slender; peduncle slightly pubescent ; 
pedicels nodding, 7 mm. long; bracts and bracteoles deciduous. Flowers about 1-5 cm. 
long. Calyx ribbed, pubescent outside, with five acutely triangular teeth. Veadlum 
finely mottled outside, with two sessile appendages on the claw. Fruits very narrow, 
about 15 cm. long and 2-5 mm. broad, glabrous, straight or very slightly torulose. Seeds 
oblong, rounded at the ends, 3 mm. long, brownish.

We have seen rather an imperfect specimen of this species, which appears distinct 
on account of its hairy calyx tube.
