A small tree 20 ft. high, with rusty-pubescent branches. Leaflets oblong- 

 lanceolate, firmly coriaceous, 10 cm. long, 3 cm. wide, glabrous above softly sparsely 

 pubescent with longish adpressed ash-grey hnirs beneath, veins about 10 pairs 

 slender bnt prominent beneath, depressed above, secondary venation indistinct 

 beneath not visible above, apex acute with a short finely acnminate sub-mncronulate 

 tip, base shortly cuneate, petiolules 3*5 mm. and main-rachis 16 cm. long, rusty- 

 pubescent. Flowers in axillary branched panicles 14 cm. long, rusty-pubescent as 

 are the pedicels 2 mm. long, bracts and bracteoles ovate, 2" 5 mm. long, 15 mm. wide, 

 acute, deciduous, rusty pubescent. Calyx campanulate, rusty-pubescent both outside 

 and inside, 8 mm. long, teeth triangular hardly as long as the tube. Corolla and 

 Stamens not seen. Pod subsessile, irregularly orbicular if 1-seeded, oblong if 

 2-seeded, with a broadly triangular unilateral tip, 1*3 cm. wide, 2-3 25 cm. long, 

 lineate between the seeds; valves thin, woody, rigid, black, glabrous, swollen 

 opposite the seeds; seeds 1 or 2, bright scarlet, 8 mm. long, 6 mm. wide, 5 mm. 

 thick, with white hilum and no arillus. 



This species is most nearly related to 0. sumatrana ; its chief interest lies in 

 its being the most northerly representative of the % Amacrotropis, all the other 

 known members of which are Malayan.
