CHAMTDOBALANUS. 



are in the young state comparatively smooth, and do not completely envelope the glans; 

 but as they ripen, they become boldly but bluntly tuberculate, and finally envelope the 



entire glans, covering even the insertion of the styles. In texture the cupules are 



brittle and crustaceous, not fibrous.

71. Quercus reflexa, King in Hook. fil. Fl. Br. Ind. v. 616. 



Young parts minutely pulverulent-pubescent. Leaves thinly coriaceous, oblong to 

 eliiptic-oblong, shortly acuminate, entire, slightly narrowed to the sub-unequal base ; main 

 nerves 8 to 12 pairs, alternate, prominent below; upper surface at first minutely 

 cinereous-pubescent, ultimately shining and glabrous, except the midrib and nerves ; lower 

 surface rather pale, minutely furfuraceous-pubescent, especially on midrib and nerves; 

 length of blade 4*5 in. to 6 in., breadth 1'75 in. to 2 in.; petiole about *25 in., stout, 

 cinereous-pubescent. Fruit-spikes solitary, axillary, erect; the rachis puberulous, minutely 

 lenticellate. Cupules solitary, sessile, ovoid-conic, pubescent, completely covering the 



glans, and bearing externally many subulate, reflexed, sub-ligneous, spine-like, scales; 



nearly 1 in. long and '75 in. in diameter. Glans of the same shape as the cupule, and 



completely covered by but separable from it, minutely tomentose, crowned by the 



united styles.

Flowers of this are not known. Its affinities are with Q. lappacea, Roxb., but its 

 leaves are less hairy, and its cupule completely envelopes the glans, apparently even 



when ripe.

72. Quercus Junghuhnii, Miq. FL Ind. Bat. i. 1. 853. 



Young shoots thin, dark-coloured, sub-glabrous. Leaves coriaceous, lanceolate or 

 ovate-lanceolate ; the apex caudate-acuminate ; the edge coarsely serrate in the upper 

 half ; the base acute or sub-acute ; upper surface glabrous, shining ; the lower densely 

 covered with pale, rufous, minute, furfuraceous tomentum; the nerves 8 to 10 pairs, 

 prominent below ; length of blade 2*5 to 4*5 in., breadth *8 to 1*4 in. ; petiole '2 in 

 to *3 in. Male spikes in lax, axillary, terminal and erect panicles; flowers sub- 

 glomerulate, 6 partite; stamens about 12. Female spikes longer than the leaves, solitary, 

 axillary ; the rachis lenticellate ; the flowers distant, solitary, sessile, ovoid ; their 

 involucres squamose-tuberculate. Ripe acorns obliquely ovoid ; the cupule woody, closely 

 enveloping the whole of the glans, internally villous, externally minutely fulvous- 

 tomentose, and with many stout, sub-recurved tubercles which are sometimes obscurely 

 arranged in zones; length *6 to *75 in., diameter about '5 in. Glans ovoid-apiculate, 

 flattened on one side ; the base truncate, adpressed-pubescent. — Miq. in Ann. Mas. Lugd.
