21. Sesbania Kirkii * n. sp. 
Stems slightly ridged or nearly smooth, not prickly, rather stout, about 5-6 mm. thick. 
Leaves up to 30 cm. long, more than twice as long as the inflorescence ; rachis sparingly 
pilose when very young, soon glabrous or with one or two small prickles on the lower side 
towards the base; leaflets up to about 35 pairs, shortly stalked, elongate-oblong or linear- 
oblong, slightly unequal-sided at the base, rounded and mucronate at the apex, 2-5-3 -5 em. 
long, about 5-6 mm. broad, spotted with minute black dots on the upper surface, otherwise 
glabrous, with several faint lateral nerves; stipules persistent, lanceolate or linear- — 
lanceolate, acutely acuminate, 1 cm. long, pubescent inside; stipels distinct, subulate, 
about 1 mm. long. Inflorescence several flowered, racemose, slender, up to 14 em. long; 
peduncle slender, broadened towards the base and there provided with numerous subulate 
spreading prickles ; bracts persistent, longer than the pedicels, linear-lanceolate, very acute, 
5-6 mm. long, sparingly ciliate; pedicels about 4 mm. long, slender, glabrous, with a 
pair of persistent bracteoles a little more than half as long as the calyx. Calyx campanulate, 
turbinate at the base, 4 mm. long, with five triangular lobes about 1 mm. long, the latter 
minutely ciliolate. Petals as in S. tetraptera Hochst. Fruits much shorter than the leaves, 
about 15 cm. long and nearly 1-5 cm. broad, stipitate for about 1 cm. at the base, very 
acutely beaked, acuminate, broadly four-winged. Ripe seeds not seen.
