cuneate, pilose above, silky strigose beneath, 5 in. long, 1 to 3 in. 
wide; petioles ‘6 to *8 in. long or longer. Peduncles 3 to 6 in.

ovate blunt, -25 in. long, silky outside, red inside. Corolla 1*5 in. 
long, tubular-campanulate, hairy outside. Capsule -4 in. long, 
globose chartaceous. Seeds grey-velvety hemispheric. Hab.

(2) A. mollis Choisy, Conv. Or. 38. Lettsomia argentea Ridl. 
Journ. F.M.S. Mus. vii. 47. 
Shrubby climber covered with silvery hairs all over. Leaves 
lanceolate, mucronulate acuminate blunt, narrowed to base, sub- 
coriaceous, silky all over, *3 in. long, 1 in. across; petioles -5 in. 
long. Cymes lax, silky, 3- to 4-flowered; peduncle *5 in. long. 
Sepals (in flower -3 in. long, elliptic blunt, silky hairy. Corolla 
2-5 in. long, white with pink edge hairy outside). Sepals, in fruit 
thinly white silky orbicular, sub-equal, glabrous inside. Berry 
globose, 2-celled with thick red pulp. Hab. Kedah Peak at 2500 
to 3000 ft. altitude (Robinson). 
This fruiting specimen much resembles some specimens of A. mollis of 
Java. As the berry is distinctly 2-celled, and not 4-celled (given as the 
character of Lettsomia ), I referred it to that genus. The habit, however, 
silky covering and fruit not projecting from sepals, make it more like Argyreia. 
I refer it with some doubt (until better specimens are obtained) to A. mollis. 
The description in brackets is taken from Javanese specimens. 
4 . LETTSOMIA, Roxb.
