Lotononis,] XLVII, § PAPILIONACEE (BAKER). 7 
bluntish with a faint mucro. Flowers 6-18 in dense racemes on leaf- 
opposed peduncles 6-36 lines long. Pedicels }—1 line long, with a 
minute linear bracteole. Calyx } in., turbinate, glabrous, the 4 upper 
teeth lanceolate-deltoid, shorter than the tube, the lowest narrower. 
Corolla pale yellow, twice the calyx, the standard ovate-acuminate, the 
keel-petals 1 line broad. Pod linear, compressed, 6-8 lines long, 
# in. broad, upeurved, glabrous, 15—20-seeded. 
Lower Guinea. Angola; Huilla and Pungo Andongo, Dr. Welwitsch! 
Identical with the last in general habit; differing principally in the stipules and 
calyx-teeth. 
2. ROTHIA, Pers.; Benth. et Hook. f. Gen. Plant. i. 477. 
Calyx deeply 5-cleft, with subequal divisions. Standard spathulate 
in our species ; wings narrow; keel-petals scarcely adhering to one 
another. Stamens united in a tube slit above; anthers small, uniform. 
Ovary sessile, multiovulate ; style straight glabrous; stigma capitate. 
Pod lanceolate, falcate, inflated, dehiscing by the upper suture.— 
Annual diffuse herbs. 
Two closely alliéd species, the other inhabiting India and Tropical Australia. The 
genus forms an exception to the rest of the Tribe by its uniform anthers. 
1. R. hirsuta, Baker. A diffusely branched annual about half a 
foot high, the branches densely clothed with long silky grey pubes- 
cence. Petioles 3 lines, Leaflets 3, subsessile, oblanceolate, 6-9 lines 
long, acute, both sides silky. Flowers 2-5 on short pedicels, sessile 
or nearly sessile from the axils of the leaves. Calyx silky, 2-24 lines 
deep, the lanceolate teeth reaching more than halfway down. Corolla 
whitish-violet not exserted. Pod sessile, 4 in. long, very silky, many- 
seeded.— Xerocarpus hirsutus, Guill. et Perr. Fl. Seneg. 169. t. 44.

Lower Guinea. Huilla, Angola, 5500 ft. Dr. Welwitsch! 
3. CROTALARIA, Linn.; Benth. et Hook. f. Gen. Pl. i. 479. 
Calyx with a campanulate tube and five distinct equal or subequal 
teeth. Petals subequal; standard orbicular or ovate with a short claw; 
keel distinctly suddenly or gradually rostrate, much upeurved. pas! 
sessile or stalked, bi- or multi-ovulate; style abruptly bent upwards 
near the base, bearded along the inner side. Stamens united in a tube 
slit along the top; anthers dimorphous. Pod sessile or distinctly 
stalked, round, oblong, or linear, continuous within, turgid.—Herbs or 
shrubs with simple or digitately trifoliolate (in one Trop. African species 
multifoliolate) leaves. Flowers in racemes sometimes congested, ter- 
minal or leaf-opposed or rarely in the axils of the leaves. Bracts and 
Stipules usually minute, setaceous. 
A large genus spread throughout the Tropical regions of both hemispheres, with its 
ead-quarters in Tropical Africa. Several species extend to the Cape.
