specimens of it were absent from all the great Eui-opcan collections nntil the distribution
from Kew of Maingay's plants. 51. Do Candolle (not having seen a specimen) suggests
in the Prodromus the identity of this with <2. Imcecefolia, Roxb., which, however, it does
not really resemble. On bis unpublished figure Roxburgh has written the name cunéala as
an alternative to lucida, and "Wallich adopted the former in his Catalogue as above noted.
The nearest ally of this is Q. omalkos, Korth,

or oblanceolate, entire ; the apex blunt (rarely shortly cuspidate) ; both surfaces quite
glabrous and shining; nerves 10 to 14 pairs, slightly prominent on both surfaces; the
reticulations distinct on the lower, and the midrib strong; length of blade 2 to 4 in,,

at elevations of from 500 to 3,000 feet.
A handsome tree, 50 to 100 feet in height, not uncommon in Perak. This is nearly
allied to Q. lucida, Roxb,, but the leaves of this are smaller, thinner in texture, and with
much mj r e distinct nervation. Moreover, they dry of a pale olive-green colour, while those
of lucida di-y of a deep brown.

Young branches pale, lenticellate, glabrous. Leaves coriaceous, elliptic or sub-obovateelliptic,
entire, shortly and abruptly cuspidate ; the base rounded or acute; upper surface
glabrous and shining, lower dull, covered wit-h a layer of minute, pale, lepidote pubescence;

panicles; the female flowers few. MaU flowers solitary or sub-glomerulate. Uipe cupules

saucer-shaped, puberulous, embracing the lower third of the glans, 1'6 in. in diameter and
2 in. deep; the lamellas about 5, rather prominent, entire, sharp-edged. Glans depressed-

Western Java,—Teysmann.
A fine species with It-aves almost undistinguishable from those of Q. costata, but with
a different fruit. Moreover, the young branches of this are pale and lenticellate, while
those of Q. eostata are dai-k-coloured and smooth. This has shorter panicles than cos¿'Jfa.

Young shoots glaucous. JgatJes with large sub-falcate persistent stipules, thinly coriaceous,

solitary, or in small panicles shorter than the leaves. Male perianth 6-cleft ; stamens 12 ;
rudimentary ovary largo and pubescent. Cupules on rather a slender rachis longer than
the leaves, sessile, solitary; when young campanulate and covering two-thirds, when ripe
saucer-shaped and covering only half, of the glans; 1-75 in. in diameter and- 4 in. deep;

This is allied to Ö. platycarpa, Bl. by its fruit, but the glans of this is much longer.
In leaf this closely resembles induta, Bl. The persistent stipules of this species are very
remarkable, and afford an excellent diagnostic character.

acuminate, with entire, slightly-recurved edges; the base acute or acuminate; upper
