spreading ; branchlets stout, smooth, angular, glabrous, purplish- 
brown when dry, sparsely lenticellate ; bud-scales lanceolate, tawny- 
puberulous, nearly 1cm. long. Leaves coriaceous; oblong or oblong- 
lanceolate, acuminate often caudately at apex, acuminate at base; 
upper surface glossy dark green when fresh, brown and shining when 
dry, when young sometimes lepidote, lower silvery grey when fresh, 
yellowish-glaucous when dry with dense minute pale tomentum ; 
margins entire, recurved; 15—30 cm. long, 5—10 em. broad ; midrib 
very stout and prominent, raised on both surfaces; main nerves 
16—20 pairs, conspicuous, parallel, oblique, slightly impressed above, 
slightly curved to and along the margin, the apical ones meeting 
in loops; transverse nervules very many, fairly regular and parallel 
but curved, joined by rather obscure smaller nervules; petiole stout, 
1—2cm. iong, the upper end bordered by the decurrent margins of 
the blade; stipules ovate, tawny-puberulous, very caducous. Spikes 
about 10—12 cm. long, & or androgynous, solitary or in small 
axillary or terminal panicles on the new branchlets; rhachis angular, 
minutely puberulous or subglabrous; bracts ovate acute; bracteoles 
ovate acuminate, very many, usually 1 toeach og and 2toeach 9

Fruits very large, sessile on a thick rhachis up to 12cm. long; cupules 
very thick (to 1 cm.), saucer-shaped, embracing half the acorn, the 
margins rounded and incurved, 4°5—6 cm. in diam. 2—2°5 em. high, 
minutely tomentose without; lamellae up to about 10, rounded, 
the margin wavy, indistinct and irregular; acorn flattened, much 
depressed at the top, broadly attached at base, densely and minutely
