surfaces alike, nerves very faint; petiole 1-1 in. Cymes solitary or in pairs, 3-1 in. 
diam.; many-fld.; peduncles shorter or longer than the petioles. —Calya-lobes 
obtuse. Corolla + in. diam., thick, pubescent on both surfaces; tip of lobes keeled 
and thickened on the face, most so at the tips; tube glabrous, shining from the adnate 
corona which is continued halfway down the middle of the lobes. — Follicles 23-3 in. 
long, 3-2 in. diam., turgid, straight, smooth, almost woody ; beak thick, curved. 
Seeds $ in., long, narrowly ovoid.—I think this hardly differs from an East African 
species.

The Punsap and Scrinpg, eastwards to the Jumna.—Disrris. Beluchistan, Arabia,

A glabrous shrub 3-4 ft. high, with long erect twiggy branches. Leaves when 
present 3-4 by } in., acuminate, shortly petioled, leathery. Flowers as in L. reticu- 
lata, but smaller, À in. diam. Follicles 5 in. long, 4 in. diam., terete, straight, pro- 
duced into a very long slender straight beak. 
48. ORTHANTHERA, Wigh. 
An erect twiggy leafless shrub. Flowers small, in dense-fld. peduncled 
woolly cymes. Sepals lanceolate, eglandular. Corolla salver-shaped, tube 
ovoid, equalling the lanceolate valvate lobes. Corona double; corolline of 
minute scales between the corolla-lobes ; staminal a raised undulate ring below 
the anthers. Column ovoid, anther-tips inappendiculate ; pollen-masses globose, 
sessile, erect. Stigma included, flat, 5-gonal. Follicles elongate, cylindric, 
opening out flat after dehiscence. Seeds comose.

Nortu-west Invi ; along the base of the Himalaya, alt. 1-3000 ft. from Peshawur 
and the Punjab to Oudh. 
Branches stout, erect, as thick as a crowquill Peduncles 4-1 in.; flowers 
shortly pedicelled, very woolly. Sepals equalling the corolla-tube. Corolla villous 
outside, glabrous within; lobes keeled down the centre of the face.  Follicles erect, 
5 in. long.— The long sepals and salver-shaped corolla are such strong generie 
characters that I do not follow the “Genera Plantarum” in uniting this genus with 
Leptadenia. 
49. BRACHYSTELMA, Br. 
Erect or twining pubescent or glabrous herbs with tuberous roots. Leaves 
opposite, sometimes very narrow or minute. Flowers few, in axillary sessile 
umbels or solitary, pedicels very slender. Corolla (in the Indian species) 
rotate; lobes 5, elongate, valvate. Corona short, adnate to the column, annu- 
lar, variously 5-10-lobed or -toothed, lobes or teeth erect or incumbent on the 
anthers. Column very short; anthers ovoid, tips inappendiculate, retuse; 
pollen-masses one in each cell, sessile, globose, erect, one margin pellucid. 
Stigma nearly flat. Follicles slender, smooth. | Seeds comose.—DisTR1B, About
