Blastus Cogniauxii, Stapf in Hook. Ic. PI. t. 2311. A shrub, 6 to 

 10 feefc 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. Galyx shortly tubular, scaly, the teetli 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 DC. Mon. Phan. VII, 421.

 or 10, equal ; anthers oblong, obtuse at the top, opening with one pore, 

 at the base shortly produced or not ; connective with or without an

 simple, filiform ; ovules very many, placentas axile. Capsule globose,
