 broadly oblong, with very obtuse or truncate apex and broad oblique 

 minutely cordate base ; both surfaces glabrous, the upper shining, the

 long as the leaves, axillary, slender, rusty-tomentose; pedicels slender, 

 •25 in. long, as long as the flowers. Sepals orbicular, only half as long

4 Roureopsis, Planch. 



Sarmentose or scandent shrubs. Leaves unequally-pinnate, leaflets 

 few. Flowers in axillary racemes ; pedicels slender, bracteolate at the 

 base. Sepals oblong, slightly imbricate, somewhat enlarged and spread- 

 ing, but not clasping the base of the capsule. Petals linear-oblong. 

 Stamens 10, the alternate longer. Ovaries 5, styles slender. Capsule 

 linear-oblong, straight. Seed ovoid ; testa thin, black, arilliform at the 

 base ; cotyledons amygdaloid. — Distrib. Species 3, all Malayan. 



This genus differs from Rourea in having straight (not curved) follicles at the 

 base of which the persistent sepals are free, and also in having bracteoles at the base 

 of the pedicels.
