Valleys of the outer Himalaya from Hazara to Bhotan; Khasia Hills at elevations of
Hbout 5,000 feet. Distribution: Japan.
T h i s - i s a widely distributed species, and presents some variety of form. As I have
remarked under Q. lineata, Bl., I doubt whether it should not be united with that species.
The only distinction between the two which appears to me to approach constancy is the
form of the acorn. Loudon {Encyc. of Trees, 688) seems first to have suggested the identity
of annulatu, Sm. with glauca, Thunbg. Blurae (in 3ius. Lugd. Bat. i. 303) gives four
varieties of this from Japan (viz. nudata, faseiata, stejiophi/lla, and caesia). These forms differ
chiefly in leaf characters: there are some excellent remai-ks upon them in Franehet and
Savatier's work above quoted. Q. annulata, Korthals, is Q. Teysmannii, Blume.

This species is very poorly represented in collections, and I have nowhere seen ripe
f r u i t . I give a figure of the ripest I have seen, and it is manifestly immature. The
young twigs of this are remarkably lenticellate. The original specimens in Leiden beai'
the MSS. name Q. caesia. The Quercus named argentata in the late Dr. Hance's herbarium
(now in the British Museum) does not appear to me to be ths true plant of Korthals. It
has a narrow, deep, sub-cylindric, boldly-lamellate cupule, from which half the glans is

exserted. Signor Beccari's Bornean specimens (Nos. 2243 and 2251) come very near to
this species, but they have much more coriaceous leaves, rounded, not narrowed at tlio
base, with fewer nerves, longer petioles, and the bark of the branches Is very scantily
lenticellate. I have named Beccari's plant Q. nivea.

Bai-k of young branches very pale, glabrous, not lenticellate. Leaves on long slender
petioles, rigidly coriaceous, ovate-lanceolate, acuminate; the edges entire, revolute ; the
base rounded or suddenly and slightly narrowed just above the petiole; upper surface
glabrous and shining; the lower very pale, silvery, glaucous, especially when young;

afterwards glabrous and shining; length of blade 3'5 in. to 5 in., breadth 1 in. to 1-75

pubescent, axillary, pendent panicles, shorter than the leaves; flowers distinctly glomerulate ;
perianth, stamens, anthers broad. Female spikes solitary, axillary, very short and fewflowered,
or in a small panicle at the base of the current year's shoots. Gupules solitary,
sessile, turbinate when young, when mature hemispheric, tapering to the base; lamella;

This resembles Q. argentata, Korth., but is distinguished from it in the points noted
under that species. The leaves of this are beautifully white beneath, especially when
young. The drooping male spikes with glomerulate male flowers mark it emphaticall}'- as
a Cgclohalanopsis, -in spite of its having entire leaves.
