pubescent. Mature female spikes rather longer than the leaves, solitary, axillary; 

 the rachis very thick, lepidote-puberulous, much lenticellate, the flowers solitary. 

 Acorns solitary on very stout, short, pedicels; depressed-turbinate when young, 

 hemispheric-conic when adult; the cupule closely enveloping the whole of the glans 

 except the styles; when young echinulate-puberulous, when mature faintly banded; -75 

 in. in diameter and *6 in. long. Ripe glans conic-hemispheric with a truncate base.—

A tree, 40 to 50 feet high. In the half-ripe condition the glans of this species is 

 concave at the base and very much depressed; when mature it becomes more hemi- 

 spherical with a conical apex and truncate base. The cupule splits irregularly but 

 vertically in its upper half when it is quite ripe, thus allowing the glans to escape. I 



its leaves this somewhat resembles Q. Cantleyana, King, and cyclophora, Endl.; but it 



differs from both entirely in its fruit. This species is represented in the Leiden 

 Herbarium by three leaf specimens, some male spikes, and a single acorn. Two of 

 the leaf specimens are named apparently in Korthals' own handwriting. The leaves of 

 these are thinner in texture than my Perak specimens, but otherwise they agree. 

 There is a single specimen from Leiden in M. De Candolle's Herbarium. Korthals' 

 excellent figure and description, however, leave no doubt as to this species.

69. Quercus discocarpa, Hance Journ. of Botany for 1874, 242 



Young shoots covered with minute furfuraceous tomentum, lenticellate. Leaves 

 coriaceousr lanceolate or oblong-lanceolate, shortly acuminate, entire; the base acute; 

 upper surface glabrous, the lower minutely ruf ous-tomentose ; the 9 or 10 pairs of nerves 

 thin, but prominent; length of blade 3'5 in. to 5 in., breadth 1-25 in. to 2 in.; petiole 

 25 in., stout. Spikes in erect, terminal, spreading, tomentose panicles ; the female spikes 



short, few in number, and only at the apices of the panicles ; female flowers solitary 

 Ripe fruit -5 in. long and -75 in. broad, sub-sessile, hemispheric or turbinate ; the base 

 truncate and concave ; the iuvolucre completely investing the whole of the glans except 

 the styles, minutely tawny-tomentose, and bearing numerous tufts or broken^ lines of 

 simple or branching, spreading, pubescent, sharp-pointed, thin spines, from -15 in. to -3 

 in. long. Glans of the same shape as the involucre, twice as broad as long, minutely 

 adpressed-pubescent ; the base very concave. -Hook, fil Fl. Br. Ind. v. $16.- Castanopsis

Mr. Kunstler describes this as a tree from 100 to 130 feet high. In leaf it resembles 

 Castanopsis, but the fruit is quite different. Hance originally described this as a Quercus, 

 but he subsequently considered that, if the genus Castanopsis is to be kept up, it must
