A shrub 1 ft. , leafless during inflorescence ; branchlets w'th smooth greyish bark. 

 Leaves 5-6 by 3-4 in., oblong or ovate-oblong, o!,tu-e or sub.-ieute, base truncate or 

 cordate, glabrous above and beneath, lateral nerves 15 pairs, scarcely prominent ; 

 petiole 1-1 i in. Panicles 6-9 in., axillary and terminal, lax, bram-hes divaricate: 

 pedicels ^ in. Flowers sweet-scented. Cab/. '- (/im nfx ,\ in., nv.it''. aeute, glabrous, 

 margins ciliolate. Petals -?? in., pale citron-colour. Stan/em l.'i, filaments very short ;

 acuminate, panicles terminal or lateral from the axils of fallen leaves, 

 flowers rather crowded, calyx-segments narrowly deltoid-ovate glabrous 

 dark-coloured. S. robusta, A. DC. Prodr. xvi. 2, 628 (not of Gcertn.). Hopea

 mature at the time of flowering, base rounded; lateral nerves about 15-20 pairs; petiole 

 - in. Pedicels i in. Flowers rather larger than in S. Ta'ura. Calyx-segments 

 glabrous, ciliolate. Anthers with a very long seta. Fruit unknown, but this and the 

 next species are evidently closely allied. It has nothing to do with S, robusta, to which 

 A. De Candolle can have referred it only through some contusion of specimens.
