 opeii, scales imbricate, lanceolate, cuspidate. Leaves entire, glabrous, 

 shining, coriaceous, thick and firm, elliptic-lanceolate or oblanceolate,

 subulate bracteoles between the flowers. Perianth-segments 5-6, stamens 

 10-12, surrounding a tomentose rudimentary ovary. .Fruit in sessile 

 clusters of 3-5, arranged in erect spikes with woody rachis, 9-12 in. long.

Other common Indian evergreen Oaks of this section with entire leaves and 

 spicate fruit, are : 1. Q.feTiestrata, Roxb., glabrous ; scales of cup imbricate, nearly 

 connate, apex free, spreading. East Bengal, Burma. Wood hard, warps much, 

 medullary rays very broad. 2. Q. dealbata, Hook, f & Th. (probably identical 

 with Q. acuminata, Roxb.), leaves white-hoary beneath, scales of cup imbricate. 

 East Bengal, Burma. 3. Q. lappaeea, Roxb., with pubescent membranous or 

 thinly coriaceous leaves, upper half of cup-scales free, spreading. East Bengal, 

 Burma. 4. Q. lanceoefolia, Roxb., glabrous ; cup with concentric bands, with- 

 out scales, enclosing f of acorn. A species differing from most other Oaks by 

 a ruminate albumen, and by the structure of the wood, which has very fine 

 medullary rays. East Bengal, Burma.
