subulate or compressed ; stigma small, terminal. Upper suture of the 

 pod nearly straight, the lower sinuated, articulations compressed, 

 transversely reticulated, indehiscent. — Herbs remarkable for their large 

 imbricated bracts. 

 The two other species inhabit the East Indies. 



1. G. lupulina, Planch, in Herb. Kerv. Stems a foot or more long, 

 herbaceous, glabrous, copiously branched at the base. Stipules broadly 

 ovate, J-f in. broad, not at all adnate, the point bluntish. Petioles 

 slender, glabrous, about half an inch long; rachis about the same 

 length, the leaflets in 2-3 pairs, and a terminal one, the former short- 

 stalked and with deciduous setaceous stipellae, both sides glabrous, the 

 lower slightly sglaucous. Flowers in dense oblong spikes 1-2 in. long, 

 on slender, erecto-patent peduncles about equalling them. Bracts 

 wrapped round the axils, J-f in. long, f in. deep, obliquely reniform, 

 much imbricated, not ciliated, membranous, with a network of fine 

 prominent veins, and a single flower in the axil of each" Pedicel 

 glabrous, nearly equalling the glabrous calyx, which is 2 lines deep, 

 cleft nearly to the base. Corolla bright yellow, twice as long as the 

 calyx. Pod equalling the corolla, with two roundish articulations, one 

 sometimes abortive. — Benth. Linn. Trans, xxv. 298. Scemmeringia 

 psittacorhyncha, Webb Spic. Gorgon. 123. 



Upper Guinea. Sierra Leone, Afzelius! Senegambia, Hevdelot! 

 General habit of the Indian O. cristata, in which the bracts are densely ciliated. 

 Also a plant of the Cape Verde islands. 



40. STYLOSANTHES, Swartz. ; Benth. et Hook. f. Gen. Plant, i. 517. 



Calyx with an elongated filiform tube and scarious lobes, the four 

 upper ones connate, the lowest distinct. Flowers polygamous, the fer- 

 tile ones often apetalous ( Welrvitsch). Petals and stamens inserted at 

 the throat of the tube ; standard orbicular ; wings oblong, free ; keel 

 incurved, subrostrate. Stamens all connate in a closed tube ; the an- 

 thers alternately longer and fixed near the base, and shorter and ver- 

 satile. Ovary nearly sessile at the base of the tube, 2-3-ovulate. Style 

 long, filiform, after flowering broken at the middle or near the base, 

 the portion that remains becoming decurvedj stigma minute, ter- 

 minal. Pod subsessile, compressed, crowned with the persistent curved 

 base of the style, the articulations usually two, sometimes solitary, 

 rugose-reticulated. — Perennial, often viscous herbs or undershrubs. 

 Leaves pinnately trifoliolate. 



A small Tropical genus, principally Brazilian.
