1. PoLTOSMA PARVIFLORA, King n. spec. A small tree ; yonng 

 branches slender, glabroas. Leaves membranous, narrowly elliptic, 

 sliortly caudate-acuminate, the edges sinuate-dentate in the upper three- 

 fourths, entire in the lower fourth, the base cunea^e ; both surfaces 

 glabrous, dull and dark-coloured when dry, the lower slightly paler 

 than the upper; main nerves 10-12 pairs, snb-horizontal, slightly pro- 

 minent on the lower surface only ; length 2-5-3'25 in., breadth 1-1 "5 

 in. ; petiole 'S-'S in., sparsely pubescent, channelled. Racemes ter- 

 minal, shorter than the leaves, puberulous. Flowers '2 in. long, their 

 pedicels '05 in., adpressed-pubescent ; the bracteoles linear, longer than 

 the pedicel. Calyx-tuhe narrow, nearly glabrous, tlie mouth with tii- 

 angular acuminate teeth. Petals only twice as long as the calyx, linear, 

 obtuse, pubescent externally, longer than the anthers. Fruit flask- 

 shaped, the apex crowned by the calyx-teeth and the pointed base of 

 the style, the base rounded and slightly gibbous, glabrous, '5 in. long, 

 and '3 in. in diam. 



Perak ; on Gunong Inas, at 5000 feet, Wray 4143. 



A species somewhat resembling P. ilicifolia, Blume in the shape of its leaves ; 

 but having much shorter racemes and smaller flowers, and an almost glabrous cal3'x. 

 2. Polyosma coriacea, King n. spec. A shrub or small tree ; young 

 branches glabrous, sparsely lenticellate. Leaves coriaceous, elliptic to 

 elliptic-rotund, rarely sub-obovate, the apex acute or shortly acuminate, 

 the edges entire and slightly re volute when dry, the base cuneate ; 

 both surfaces glabrous, the upper shining, the lower dull and paler ; 

 main nerves 9-11 pairs, spreading, interarching freely, slightly promi- 

 nent on the lower surface only ; lengtli 275-4 in., breadth 1-5-2 in., 

 petiole about '75 in. Racemes terminal, about as long as or longer than
