Cups flattish, rough with small scales. Nuts roundish-ovate. A large spreading tree, 80 ft. high, with compact wood. Common in the mountains of Gede, at elevations of 4000 ft. and 5000 ft. (Blume.) A most desirable species, which would probably prove hardy in the climate of London.

Q. pallida Blume F1. Jav., t. 4. and 5.; and our figs. 1837. and 1838. The pale Oak. Leaves oval. oblong, very much pointed ; acute at the base, quite entire ; glabrous; pale-coloured beneath. Catkins terminal, diæcious; the male catkins branched, fastigiate; the female ones simple. A tree, from 50 ft. to 60 ft. high; flowering in June and July. Found by Blume near the sources of the river Tji. barrum, in the mountains of Gedé. (Blume.)

Q. élegans Blume F1. Jar., t. 10., and our fig: 1839. The elegant Oak. Leaves obovate, or oval.oblong, bluntly acuminate, narrowed into the petiole, glabrous. 1837 Fruit in long spikes. А magnificent tree, with a thick trunk, frequently at. taining the height of 60 ft.

Q. glabérrima Blume Fl. Jav., t. 8. ; and our fig. 1842. The smoothest-leaved Oak. Leaves ellipticoblong, bluntly acuminate ; obtuse at the base; very glabrous. Fruit in dense oval or roundish spikes. A beautiful tree, from 25 ft. to 30 ft. high, with leaves from 4in. to 7 in. long, and from Ijin to S in. broad. It is found upon the volcanic mountain of Gede, as well as on those surrounding it, at elevations of 4000 ft. or 5000 ft. It is somewhat allied to Q. squamata Smith ; which, however, has the spikes much more elongated. (Blume.) This appears also a desirable species for introduction.

the edge. This is a very splendid species, from the great size of its racemes and acorns. Punning Punning is the generic appellation of the oak in Malay: in the Rajang dialect it is called Pasang.

l. gemellifòra Blume Fl. Jav., t. 17. ; and our fig. 1847. The twin-flowered Oak. Leaves oblonglanceolate, sharp at both ends, remotely serrated, glabrous; glaucous beneath. Female peduncles generally 2-flowered. A middle-sized tree, a native of the lofty mountains of Salak and Kandang. The wood is very compact, aná excellent for building purposes. (Blume.)

Q. induta Blume FI, Jav., t. 12. ; and our fig. 1848. The cloth-cupped Oak. Leaves oval-oblong, acuminate; acute at the base ; glabrous; downy beneath. Cups tubercled, without teeth. Nuts de pressed and hemispherical. A handsome tree, 100 ft. high, found on Mount Gede. (Blume.)

Q. urceolàris w. Jack. Hook. Comp. Bot. Mag., i. p. 256. Leaves elliptic-oblong, long and slender at the point, quite entire, glabrous. Fruit spiked. Cup somewhat hemispherical, with a spreading limb. A tree, with rough bark, a native of Sumatra. Leaves alternate, petiolate, terminated by a long slender acumen ; coriaceous, pale beneath ; 8 in. to 9 in, long. Fruit on lateral racemes. Acorns rounded and flattened at top; umbilicate in the centre, and mucronate with the three persistent styles ; rather perpendicular at the sides, half-embraced by the calyx, which is cup-shaped, marked on the outer surface with small acute scaly points, concentrically arranged, and whose margin expands into a spreading, nearly entire, waved limb. The ovary is three-celled, each cell containing two ovula, and is lodged in the bottom of the large funnel-shaped calyx. The acorn contains a single exalbuminous seed, placed a little obliquely. The spreading limb of the cups forms a good distinctive character, and renders this a very remarkable and curious species.

l. Pseudo-molúcca Blume Fi. Jav., t. 6.; and our fig. 1849. The false Molucca Oak. Leaves 1849 elliptic-oblong, acuminate; acute at the base ; glabrous ; shining above, glaucous beneath. Cat. kins almost terminal. Cups not much hollowed, covered with small scales. Nuts hemispherical. A very branchy tree, found in the forests of the west of Java. (Blume.)

handsome tree, from 40 ft.
to 50 ft. high; found on
the mountain of Salak. It
is nearly allied to Q. glauca
Thunb.; but the leaves
are broader, less acute at
the base, and not glau-
cous beneath. (Blume.)
The acorns are of a very
singular shape, and are en.
closed in the cup.

App. viii. Mexican Oaks not yet introduced. The first 22 of the following oaks are described and figured in Humboldt and Bonpland's magni. ficent work on the plants of Mexico, entitled Plantæ Æquinoctiales. The 14 that follow these are taken from Nees, as quoted in Rees's Cyclopædia; and many of them are probably indentical with those of Humboldt.

Q. ralapensis Humb. et Ponp. Pl. Æquin., t. 75., and our fig. 1852., Michx. N. Amer. Syl., .. p. 109.; Roble de Duela, Span.' Leaves on long footstalks, oval-lanceolate; acute at each end, remotely toothed with bristly teeth, quite glabrous. Fruit almost solitary, sessile. (Humb. et Bonp.) A tall tree, glabrous in every part, except the cup. Branches alternate ; younger ones covered with round tubercles. Leaves crowded towards the tips of the branches, 3 in, to 4 in. long, somewhat leathery. Petioles 1 in. or 14 in. long; a little thickened towards the base, slender. Female Aowers axillary, almost solitary and sessile. Cup goblet-shaped, closely imbricated. Scales oval, membranaceous; covered on the outside with a peculiar down, scarious on their margins, and blunt at their apex. Nut ovate, obtuse, terminated by the persistent style. Very common in the forests near Xalapa, in New Spain,

at an elevation of about 4000 ft. (677 toises). From the wood, which much resembles that of Q. Robur, the Spaniards have given it the name of Roble de Ducla, that is, the Timber Oak; a name which indicates that this oak is applied to the same uses as Q. Robur. This is a valuable tree, and it will one day become of such great importance in Mexico, that the inhabitants ought to take more pains to increase it. Michaux describes it as a very lofty tree, with a trunk 2 ft. in diameter. It bears abundance of acorns, which, though they soon germinate, might, with proper care (packed in moist Sphágnum), be sent to England.
