A magnificent tree, often attaining a height of 150 feet. Owing to the difficulty of
obtaining its loaves and flowers, tHs species has been three times named from its acorns
only (picked iip under trees), and until now its leaves have not been described.
Roxburgh's original name of depressa must unfortunately give way, as Hmnboldt had
previously appropriated it for a South American species, and this circumstance having
been observed by Endlicher, he rechristened it cyclophora, without, however, describing
it. In the Calcutta Herbarium Roxburgh left a coloured drawing of the acorn, which
makes the identification of his depresm a matter of absolute ccrtainty. Wallicli issued
good specimens of this as pUcentaria, BL, but a reference to the latter's published figure
{Fl Jav. Cup. t. 9) shows that his plaoentaria is really one of the forms of the Protean
Q. spicuta, Sm. Miquel suggests that Q. cijclopliora is allied to rokindata, Bl., but the
suggestion is disposed of by an inspection of Blume's figure of the latter species {I.e.
i. 11).

Yonng shoots pale, glabrescent. Leaves thinly coriaceous, oblong-lanceolafe, acuminate;
the edges entire, slightly rccurved when dry; the base acuminate; both surfaces
dull, covered with very minute whitish pubcscenoe, sub-glaucescent; nerves 8 to 9 pairs,
much curved, ascending obliquely, prominent beneath; length of blade 7 to 11 in.
breadth 1'75 to 3 in.; petiole -3 to -5 in. Spikes longer than the leaves, axillary, or in
few-branched terminal panicles; the female spikes nearly as numerous as the male.
Male ¡¡eriantk deeply 6-clcft; stamens 12; rudimentary ovary rather small, sericeous.
Cupules sessile, solitary, depressed-globular when young and cnycloixng tlio whole of
the glans except its apex; when ripe, saucer-shaped or even discoid, wider than tlie
glans and embracing only the lower half of it, remotely and minutely denticulate,
griseous-puberulous, from -9 in. to 1-3 in. in diameter, and -25 to -35 in. deep; lamellai
about 6, broad. Glajis (globuse-cooic when young) dcpressed-turbinate when ripe, and

diameter, and about -5 in. long.—Hook. fil. Fl. Br. Ind. v. 615.

CYCLOBALANUS. '- i
A spreading tree, from 30 to 60 feet high, with spreading crown; the leaves pale
green and silvery, especially beneath. This is a very distinct and handsome specics. In
its leaves it much resembles Q. Curiisii, King, a small tree collected by me in
Penang, but the acorns of the two are very unlike. This also resembles Q. induta,
but has narrower leaves and a different acorn. The leaves of this arc undistinguishable
from those of the specimen in the Leiden Herbarium named Q. oligoneura, XCortli.
As Korthals does not describe the fruit of oUgoneura, I have treated it as a doubtful
species. At the same time I think it very likfly that EicUleri and oUgoneura are one
and the same; and if so, Korthals' (being the older name) would stand.

Young branches and leaves deciduously puberulous. Leaves oblong or elongatelanceolate,
acuminate, entire, much narrowed to the acuminate base; ujDper surface
glabrescent or glabi'ous when adult; lower surface pale, glabrescent; main nerves abolit 10
pairs, rather prominent below; length of blade 4 to 5 in., breadth 1-5 in. to nearly 2 in.;
petiole '35 to '5 in. Sjnkes terminal, solitary, or in fascicles of 2 or 3, rather longer
than the leaves, mostly androgynous; male flowers above, female flowers below; male
perianth 5-cleft, cinerescent externally; anthers about 12. Female flowers in glomeruli
of 3, sessile, minutely bracteolate, containing a number of abortive stamens; styles 3,
cylindiic, si)readiug. Eipe fruit on stout, erect rachises. Cupules solitary by abortion,
or with 2 undeveloped at the base; the cupule woody, saucer-shaped, shallow or quite
fiat, -5 to -75 in. across, embracing only the base of the glans, to which it has a broad
attachment; its scales densely pubescent, connate, except the very tips. Glans crowned
by the short remams of the united styles, depressed-globose or pyriform-globose, densely
covered with minute white tomentum when young, glabrous when very old; from -5

A considerable tree, often attaining a height of 80 to 100 feet; not unlike Q.
dealhata, Hook. fil. and Th., in foliage, but differing greatly in the fruit. This species
was collected by Roxburgh in Chittagong, and was described in his Flora Indica (iii
636) prior to 1815 under tho name Q. iurbinata. Blume's species of the same name"
but a totally different plant from Roxburgh's, was published in 1825, and (owing to th^
delay in the publication of Roxburgh's book) therefore takes precedence. °Blume's
Q. turhinata is now, however, reduced to a variety of the same author's Q. Uneata
Roxburgh left an admirable drawing of his Q. turhinata in the Calcutta Herbarium so
there is no doubt whatever us to his plant. Miquel (I.e.) gave the name Thonxsoni to
