"When he described this species, Miquel liad seen only the leaves and young spikes
which are deposited in the Herbarium at Utrecht. Si^'. Beccari's specimens have young
f r u i t , and it is one of these which I have figured. The species evidently belongs to the
Pasania group, in which its nearest allies appear to be priiinosa, Bl., and hjstrix, Korth.

This is a considerable tree, attaining a height of 40 to 80 feet, it is allied to
Q. Sundaica, Bl., and to Q. pruvnosa, Bl. From the former it is distinguished by its
gi-eater amount of furfuraceous pubescence and more oblong leaves which are narrower
a t the base, and by its more contracted inflorescence, smaller fruit with more echiuate
cupules which, until half ripe, are infundibuliform. To Q. pruinosa, BL, this is allied by
its inflorescence; but this is less furfuraceous and has smaller fruit. The leaves of
pruinosa, arc, moreover, more oval, and have much broader bases, than the leaves of this.
Blume's variety pac.hi/phi/lla (of his Q. Korthahii), Mtts. Lugd. Bat. i. 292, is represented
in his herbarium at Leiden by only a few leaf specimens accompanicd by loose cupules.
The latter in my opinion probably belong to Q. pruinosa, Bl,, as also may some of
t h e leaves. But the material is iusufBcient to form an opinion upon. Q. Korthalsii,
BL, var. kofan, is in my opinion referable to the present species rather than to Q.
Sundaica as Blume understood it. No fruiting specimen of var. kajan, BL, has come
under my observation. De Candolle considers Zollinger's specimen No. 2264 to be kajun,
but the acorns accompanying that are about 1'5 in. in diam.

Young branches, leaves, inflorescence and ripe cupules more or less minutely lepidotetomentose.
Leaves thinly coriaceous, elliptic-oblong, entire, acute or shortly and bluntly
cuspidate; the base much acuminale, slightly decurrent on the petiole; both surfaces
pale. Rlaucescent; nerves 9 to 11 pairs, rather prominent below; length of blade 5 to 7

or on short lax axillary or terminal panicles, shorter than the leaves. Male flowers subgiomerulate;

globular, when very young enveloping the "whole of the glans except the styles,
tubercular below, scaly towards the mouth. B.ipe cupules hemispheric, enveloping only
half the glans; the lower part with undulate, irregular lam e l l®; the upper part ne°ar the

The cupules, wtiich are at first ovoid-globular with entire mouths, become pyriform
as they _gi w (from the development of the glans). When ripe they are neariv hemispheric,
irregularly erose at the mouth, and sometimes slightly constricted at the base into
a short, thick peduncle. In M. De Candolle's herbarium there are put with typical
mduta some specimens without fruit of a form with longer, narrower, and more fulvous
leaves; similar specimens occur also in the collection at Leiden. These may
belong to a variety. But the var. B. described by Blume {Mas. Lugd. Bat.'u)
