EUSESBANIA. 
1. Sesbania Goetzei, Harms., in Engl. Bot. Jahrb., XXX, 327 (1902). 
A shrub 2-3 m. high. branchlets rather densely and softly grey-pubescent, the older 
ones becoming striate or somewhat angular. Leaves shorter than the inflorescence, 3-5 cm. 
long; rachis and leaflets densely and softly grey-pubescent ; leaflets about 6-10 pairs, 
shortly stalked, oblong, rounded and unequal-sided at the base, rounded and very minutely 
mucronate at the apex, 1-1-5 em. long, 3-6 mm. broad ; stipules soon falling off, triangular- 
lanceolate, acute, 3-4 mm. long, pubescent ; stipules minute. Inflorescence mostly two- 
flowered, axillary ; peduncle softly pubescent; pedicels about 5 mm. long, with two 
linear-lanceolate fugacious bracteoles towards the apex. Flower buds ellipsoid, turbinate 
at the base, subacute at the apex. Calyx widely campanulate, abruptly contracted into 
a solid turbinate base, about 5 mm. long, with five acute subulate-triangular lobes scarcely 
1-5 mm. long, sparsely pubescent outside. Vezillwm large, orbicular, about 3 cm. long 
and broad, strongly and closely mottled with purple, with two free linear curved obtuse 
appendages towards the base about 7 mm. long. Alae about 2-5 cm. long and 8 mm. 
broad. Carina 3 mm. long, the claw slightly longer than the broadly boat-shaped limb. 
Staminal-sheath 2 cm. long, free parts of filaments curved upwards and about 8 mm. long. 
Ovary with a very thin line of hairs along the top; style glabrous. Fruits not known.
