Blastus CoGNiAuxii, Stapf in Hook. Ic. PL t. 2311. A shrub, 6 to 

 10 feet high ; young branches slender, as thick as a crow-quill, scaly, 

 glabrous or puberulous. Leaves equal, oblong-lanceolate, narrowed at 

 the base, the apex acuminate, 5-nerved (the marginal pair faint), the 

 edges sub-entire ; upper surface glabrous, with a few scattered, small 

 glands ; lower glandular-punctate, minutely furfuraceous on the nerves ; 

 length 4 to 7 in. ; breadth 1 to 225 in., petiole '3 to '75 in. Panicles 

 axillary or terminal, slender, much shorter than the leaves, glandular- 

 scaly, the few divaricate branchlets bearing the flowers in dense terminal 

 glomeruli of 6 to 9. Calyx shortly tubular, scaly, the teeth minute. 

 Anthers narrowly ovate with many small yellow glands near the base. 

 Capsule subglobular, truncate, *1 in. in diam., subglabrous ; seeds 

 linear. Ochthocaris parviflora, Cogn. in DO. Mon. Phan. VII, 421. 



Perak ; common. Distrib. Borneo. 



This is closely allied to B. cochinchinensis, Lour., but differs notably in its
