Tho youngest branches and the rachises of the flower-spikes minutely griseoustomentose;
all the other parts quite glabrous. Leaces small, rigidly coriaceous, from
n a n w l y lanceolate to elliptic-lanceolate, rather bluntly acuminate; edges entire and
slightly recurved when dry; the base acuminate, rarely acute; both surfaces quite
smooth: the upper shining, the lower dull and pale; nerves 8 to 14 pairs, anastomosing
inside the margin, very indistinct; length of blade 2-5 in. to 3-5 in., breadth -75 in.
to 1-35 in. (in var. laHfolia 1-6 in.) ; petiole -25 in. to '6 in. Spikes slender, axillary,
or in sparse terminal panicles, the female lowermost. Male flowers sub-glomeru!ate or
solitary; the perianth with 6 blunt teeth; stamens Vi-, rudimentary ovary large, globose,
villous. Mature female spikes slightly longer than the leaves; the flowers sessile, solitary.
Bipe cuprdes saucer-shaped, embracing only the base of the glans, -i in. to -5 in. in
diameter and -J 5 in. deep, gradually narrowed to a short, thick pedicel; lamella; 4 to 6,
bold, entire. Glans when quite ripe sometimes globular, usually ovoid-conic; the base

A fine tree, attaining sometimes a height of 80 feet.
Specimens from Sumatra differ from those from Penang and Perak in having the
petioles rather longer and more slender. The species is a very well-mai-ked one, readily
distinguished by its narrow, very coriaceous leaves. Its nearest allies are Q. Miquelianai
ScheS., and Wemigiana, King, but both these species have larger fruit.

56. QUERCUS CYRTOEHYNCHA, Miq. Fl. Ind. Bat. Siq)pl. 350.
Young shoots puberulous or glabrous. Leaves thinly coriaceous, elliptic-oblong, acute,
entire; the base acute or sub-acute; upper surface glabrous, not shining; lower paler,
minutely puberulous or glabrous; nerves 10 to 14 pairs, slightly prominent below; length
of blade 5 to 8 in., breadth 2-5 to 3 in.; petiole -25 in. 3iale spikes in large, spreading,
puberulous, terminal, panicles much longer than the leaves; female flowers on androgynous,
solitary, axillary spikes. Male flowers sub-glomerulate; perianth 6-dentate; stamens
12. Female flowers solitary, or 2 or 3 connate, ^ipe eupules solitary, sessile, on stout
rachises longer than the leaves; when young campanulate, when adult saucer-shaped and
embracing only the lower part of the glans; lamella; 6 or 7, minutely tomentose, with
entire sub-glabrous undulate edges, -7 in. to -9 in. in diameter, and -2 to -3 in. deep.

CYCLOBALANUS. 67
A tree, 40 to SO feet high. In its leaves this resembles Q. Lamponga, Miq. and
Q. Smdaica, Bl, but the latter is a much more hairy plant: in its zonate eupules this
differs from both. The fragments named Q. cyrtopoda by Miquel closely resemble this
as to leaves.

Young branches minutely puberulous. Leaves coriaceous, shortly petiolate, ellipdc,
slightly oblique, entire; the apex with a rather abrupt short acumen; the base sub-acute,
unequal; upper surface glabrous, shining; the lower pale and minutely reticulate; when
young, minutely squamulose-torn entese, when adult glabrous; the midrib prominent on
both surfaces, the 10 or 12 pairs of nerves slightly so on tiie lower; length of blade
4 to 6 in., breadth 2 to 2'5 in.; petiole '4 iu. Eipe cvpules thin in texture, woody,
sub-sessile, saucer-shaped, nearly glabrous, about 1 in. in diameter and -2 iu. deep; the
upper edge slightly revolute; lamellze about 6, entire. Glans turbinate-apiculate, with a
truncate base; smooth, shining, -5 in. long and -8 in. in diameter. Male flowers

A very poor example of this in ripe fruit exists in tho Utrecht Herbarium, and forms
the type specimen of tl)e species. Dr. Wenzig (I.e.) considers that Maingay's specimen
{Ilcrh. Maing. Kew Distrib. A^o. 1527) belongs to this species. I cannot agree in this view,
for comparison shows that Miquel's specimen is quite difíerent from Maingay's. The latter
I have named Q. Wemigiana.

Young shoots puberulous or sub-glabrous. Leaves coriaceous, entire, rather broadly
elliptic or oval, abruptly shortly and bluntly cuspidate, rather suddenly narrowed in

to 12 pairs, slightly prominent beneath; length of blade 3-5 in. to 5 in., breadth S in.

longer than the leaves. Cupules solitary, nearly sessile, woody; when young, hemispheric
and boldly 3 to 4-zonate. Bipa cupula nearly flat, covering only the base of the glans,
