20. Sesbania tetraptera, Hochst. ex Baker in Oliv. Fl. Trop. Afr., ii, 136 (1871). 
Stems ridged, otherwise glabrous, about 4 mm. thick. Leaves up to 12 cm. long 
nearly twice as long as the inflorescence; rachis sparingly pubescent when young, soon 
becoming quite glabrous or with a few small prickles on the lower side towards the base ; 
leaflets about fifteen pairs, shortly stalked, narrowly oblong, unequal-sided at the base, 
truncate-rounded and sharply mucronate at the apex, 1-2-2 cm. long, 3-4-5 mm. broad, 
glabrous, spotted with minute black dots on the upper side, with no visible nerves or 
veins ; stipules subpersistent, subulate-lanceolate, very acute, 5-6 mm. long, very slightly 
pubescent inside; stipels very minute and subulate. Inflorescence a simple raceme, few 
(up to seven) flowered ; peduncle up to 6 cm. long, thickened at the base and there closely 
beset with subulate-triangular prickles; bracts linear-subulate, about 3 mm. long, per- 
sistent ; pedicels about 7 mm. long, filiform, with a pair of linear deciduous bracteoles 
at the apex about one-third the length of the calyx. Calyx campanulate, turbinate at 
the base, 5 mm. long, with five short triangular lobes, the latter minutely pubescent inside 
the margin. Vezidlum broadly orbicular, 1-2 cm. long, cuneate into a short claw about 
2 mm. long, with two linear sessile ridge-like appendages about 2 mm. long near the base. 
Alae oblong; limb 8-5 mm. long; claw bent, 5 mm. long. Carina broadly semilunar ; 
limb 8 mm. long, with an acutely triangular tooth on the upper side; claw curved, 5 mm. 
long. Staminal sheath 0-8 cm. long, free part of filaments 3-4 mm. long; anthers 0-75 mm. 
long. Ovary 8 mm. long, four-winged ; style bent at right angles, 3 mm. long, puberulous 
towards the top. Fruits much longer than the leaves, 15 cm. long, 1 cm, broad, broadly 
four-winged, stipitate, for about 1 cm. at the base, acutely acuminate at the apex. Seeds
