Pods 2-seeded, with thin margins, lance-elliptic; seeds oblong- 
reniform enclosed in the inner membranous layer of the 
valves; calyx decidedly oblique. 12. Glottidium. 
Pod 4-angled, often 4-winged, not torulose. 11. Daubentonia. 
8. Sesban Adans. Fam. 2: 327. 1763 
Herbs or shrubs with abruptly pinnate leaves and numerous leaflets. 
The flowers are borne in axillary racemes, with deciduous bracts, and a pair 
of deciduous bractlets under the flowers. The corolla is yellow or the 
banner dotted, streaked, or tinged with purple. The banner has often one 
or two callosities at the base of the suborbicular reflexed blade; the wings 
are short-clawed, the blades obliquely oblanceolate or oblong, with a basal 
auricle; the keel-petals have long claws, the blades are strongly and broadly 
lunate with a lateral auricle on the upper side. The pod is slender, terete 
or slightly compressed, short-stipitate, many-seeded, with cross-partitions 
between the seeds, 2-valved. Seeds cylindro-oblong, subtruncate at the 
ends.

The genus was established on Aeschynomene Sesban L. Scopoli (Introd. 
308. 1777) changed the name to Sesbania, the latter being better Latin 
form. 
Synonyms : 
Darwinia Raf. FI. Ludov. 106. 1817. Type: D. exaltata Raf., which has 
been known under the name Sesbania macrocarpa Muhl. 
Monaplectra Raf. FI. Ludov. 106. 1817. This was proposed instead of 
Darwinia in case the latter happened to be preoccupied. 
The genus consists of perhaps 20 species of the warmer regions of both 
hemispheres. It is represented in North America by 4 native and 3 intro¬ 
duced species. 
9. Agati Adans. Fam. 2:326. 1763 
Small trees, having abruptly pinnate leaves, with many entire leaflets 
and deciduous stipules. The flowers are large, borne in small axillary 
racemes, and with two deciduous small bractlets subtending the calyx. The 
calyx is in structure the same as in Sesban. The petals are comparatively 
narrower, the banner is without callosities, its blade oval in outline, and 
retuse at the apex; the blades of the wing- and keel-petals are obliquely 
lanceolate-lunate, tapering at the base without any distinct auricle. The 
staminal sheath and the pistil resemble also those of Sesban, except that 
they are more gradually arcuate. The pod is the same as in that genus.

The genus was based on Robinia grandiflora L.
