Western Inp1a; in dry forests, from Lahore and Behar to Mysore, common.—

Generally resembling R. ornata, but the hair on the stems beneath the leaves and 
on the sepals is less copious, and much less white. The essential distinction lies 1n 
the sepals which are smaller and more obtuse.—Roxburgh's Lettsomia bona-nor, à 
native of Midnapore jungles, is referred to here with little doubt, though no specimens of 
it are known to exist ; the only difference his characters afford between his L. bona-not 
and his L. uniflora (Rivea hypocrateriformis) are, that the former has deliciously clove- 
scented flowers and three of them together, the latter solitary flowers, whether 
scented or no is not stated. Roxburgh’s figure is excellent. 
3, AR GYEREIA, Lour. 
Scandent, rarely suberect, shrubs. Leaves from cordate-ovate to narrow- 
lanceolate, silky hirsute or pubescent. Cymes sessile or peduncled, capitate or 
corymbose. Flowers showy, purple or rose, rarely white. Sepals from orbicular 
to lanceolate, subequal, or the inner smaller, adpressed to the fruit, often some- 
what enlarged. Corolla funnel-shaped ; limb plaited, very shortly lobed. 
Stamens included ; anthers oblong, never twisting. Ovary completely 4-celled, 
4-ovuled ; disc annular, often prominent, as long as the ovary; style filiform, 
stigmas 2 sessile globose. Fruit indehiscent, baccate or nearly dry, hard oF 
papery, 4-1-seeded. —Species 30, Indian, Malayan, and S. Chinese, one African. 
Sect. I. Pomifera. Sepals orbicular, ultimately enlarged, completely 
enveloping the fruit, strongly imbricate, glabrous, mucilaginous.

Scandent or twining, often forming low, dense masses with apple-like fruits. 
Leaves 1-4 in. diam.; petiole long. ^ Peduncles 4-3 in.; bracts inconspicuous 
caducous. Corolla 2-3 in., widely-funnel-shaped, rose-purple. Fruit 3-1} in. diam., 
including the sepals; capsule thin. Seeds 4 in., minutely rusty-villous, hilum hirsute- 
—Miquel (FI. Ind. Bat. ii. 587) says Ipomæa lilacina (Blume Bid. 716) is this 
plant, but the description does not agree (“ sepals acute,” &o.).
