Generally resembling if. 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 in 

 ' the sepals which are smaller and more obtuse. — Eoxburgh's Lettsomia bona-nox, a 

 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 hisi. bonornox 

 and his L. uniflora {Bivea 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. Eoxburgh's figure is excellent. 



3, ARGYREIA, 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, adpresaed 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 fiUform, 

 stigmas 2 sessile globose. Fruit indehiscent, baccate or nearly dry, bard or 

 papery, 4-1 -seeded. — Species 30, Indian, Malayan, and S. Chinese, one African. 



Sect. I. Fomifera. Sepals orbicular, ultimately enlarged, completely 

 enveloping the fruit, strongly imbricate, glabrous, mucilaginous. 



1. A. tilisefolia, Wight le. t. 1358 ; leaves ovate-cordate shortly acumi- 

 nate or obtuse hoary beneath or glabrescent, peduncles 1-3-fld. shorter than 

 the petioles, corolla-plaits glabrous without or nearly so. Kurz For. Fl. ii.

India, alt. 0-1000 ft., except in the western dry portion, very common in Bengal 

 and near the sea. — Disthib. Malaya to the Philippines ; elsewhere often cultivated. 



Scandent or twining, often forming low, dense masses with apple-like fruits. 

 Leaves 1-4 in. diam. ;_ petiole long. Peduncles J-3 in. ; bracts inconspicuous, 

 caducous. Corolla 2-3 in., widely-funnel-shaped, rose-purple. Fruit |-1J in. diam., 

 including the sepals ; capsule thin. Seeds ^ in., minutely rusty-villous, hilum hirsute. 

 — Miquel {Fl. Ind. Bat. ii. 587) says Ipomsea lilacina {Blume Bijd. 716) is this- 

 plant, but the description does not agree (" sepals acute," &c.).
