banks of rivers. It is nearly allied to Q. molúcca Rumph. The wood, although more fibrous and less compact than that of the common oak of Europe, is fit for building, more particularly when in water. (Blume.)

Q. pruinosa Blume Fl. Jav., t. 1.; and our fig. 1836. The frosty Oak. Leaves ovate or ovaloblong, acuminate; roundish at the base. Branchlets and leaves covered beneath with small yellowish scales. Fruit aggregate, in short spikes. Cup concave, covered with small scales. Nuts roundishovate. A beautiful tree, from 50 ft. to 60 ft. high, with a thick bark. A variety of this species has the leaves oval-oblong, and acute at each end; and the midrib and branchlets downy. Common in woods upon mountains. (Blume.)

Q. angustàta Blume Fl. Jav., t. 7.; and our fig. 1835. The narrow-leaved Oak. Leaves oblong, lanceolate; acute at each end; shining above, glaucous beneath. Catkins axillary, terminal, elongated. Cups flattish, rough with small scales. Nuts roundish-ovate. A large spreading tree, 80 ft. high, with compact wood. Common in the mountains of Gedé, at elevations of 4000 ft. and 5000 ft. (Blume.) A most desirable species, which would probably prove hardy in the climate of

London.

Q.pállida Blume Fl. 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, dicecious; 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 Tjibarrum, in the mountains of Gedé. (Blume.)

Q. élegans Blume Fl. Jav., t. 10.; and our fig. 1839. The elegant Oak. Leaves obovate, or oval-oblong, bluntly acuminate, narrowed into the petiole, glabrous. Fruit in long spikes. magnificent tree, with a thick trunk, frequently at taining the height of 60 ft. A native of the woods of

A

Q placentària Blume Fl. Jav., t. 9.; and our fig. 1840. The placenta-cupped Oak. Leaves ovateoblong, bluntly acuminate; roundish at the base; coriaceous, glabrous. Fruit in clusters. Cup covered with small tubercles. Nuts roundish, depressed. A tree, about 40 ft. high, found on the volcanic mountain of Gedé, at an elevation of 6000 ft. The wood is rarely used, although very hard, and capable of taking a fine polish. (Blume.) This species would probably bear the climate of London.

Q. glaberrima 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 4 in. to 7 in. long, and from 13 in to 3 in. broad. It is found upon the volcanic mountain of Gedé, 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. Q. costàta Blume Fl. Jav. t. 13, 14.; and our figs. 1841. 1843. The ribbed-cupped Oak. Leaves oblong, acuminate; acute at the base; glabrous; glaucous beneath. Catkins branched. Fruit peduncled. Nuts flat above, round beneath, immersed in the cup. Cups without teeth, surrounded by circular ribs. A tree, 70 ft. high, found in mountainous places. It is easily distinguished from all the others by the singular form of its cup.

Q. rotundata Blume Fl. Jav., t. 11.; and our fig. 1844. The round-fruited Oak. Leaves oblong, acuminate; attenuated at the base; glabrous; glaucous beneath. Fruit in short one-sided spikes. Cups hemispherical, scaly at the margin, but without teeth at the base. Nuts plano-convex on their upper part, rounded beneath. A tree, 70 ft. high, with compact heavy wood. It is found on high mountains, and flowers in August. (Blume.)

Q. platycárpa Blume Fl. Jav., t. 15.; and our fig. 1846. The broad-fruited Oak. Leaves ovaloblong, acute; somewhat wedge-shaped at the base; glabrous; shining above, glaucous beneath. Fruit peduncled, in short spikes. Cups surrounded beneath by hollow rings. Nuts round, depressed. A large tree, a native of the woods in the south of the province of Bantam. (Blume.)

Q. daphnoidea Blume Fl. Jav., t. 16.; and our fig. 1845. The Daphne-like Oak. Leaves oblonglanceolate; sharp at both ends, quite entire, smooth; somewhat glaucous beneath. Fruit in long slender catkins, almost solitary. Cups surrounded by concentric rows of tubercles. Nuts ovate, sharp-pointed. A tall tree, a native of Bantam. (Blume.)

Qracemosa W. Jack. Hook. Comp. Bot. Mag. 1. p. 255.; Punning Punning Bunkars, Malay. Leaves broad lanceolate, quite entire; glabrous. Male spikes panicled. Fruit spiked., Nut umbili

cate, depressed. Cup tuberculated. A large tree, with brownish bark; a native of Sumatra. Branches smooth. Leaves alternate, short-petioled, acuminate, attenuated to the petiole; nerves well marked, and reddish beneath, 6 in. to 8. in. long. Stipules small, linear. Male spikes numerous panicled, terminal; and, from the axils of the upper leaves, which are crowded round the thickened extremity of the branch, slender, hoary; flowers sessile, aggregated. Female spikes at first terminal, becoming afterwards lateral by the shooting up of the branch: flowers numerous, dense, sessile. Males: calyx 6-parted, segments acute; stamens 15-20. The centre of the flower is occupied by a densely villous disk. Female: calyx rugose, turbinate, umbilicate; ovary 3-5 celled; each cell con

taining 2 ovula, attached by a thread to its summit.

Acorns large, depressed, umbilicate, with a short mucro. Cup flat, embracing the nut for about half its height; nearly 1 in. in diameter, rough, with angular imbricated tubercles, which are large towards the base, and become small towards

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.

Q. gemelliflora 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, and excellent for building purposes. (Blume.)

Q. induta Blume Fl. 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 depressed and hemispherical. A handsome tree, 100 ft. high, found on Mount Gedé. (Blume.) Qurceolaris 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.

Q. Pseudo-molucca Blume Fl. Jav., t. 6.; and our fig. 1849. The false Molucca Oak. Leaves elliptic-oblong, acuminate; acute at the base; glabrous; shining above, glaucous beneath. Catkins almost terminal. Cups nót much hollowed, covered with small scales. Nuts hemispherical. A very branchy tree, found in the forests of the west of Java. (Blume.)

Q. molucca Lin. Sp. Pl., 1412., Willd., No. 11., Rumph. Amb., 3. p. 85., N. Du Ham, 7. p. 153., Smith in Rees's Cyclo., No. 11. The Molucca Oak. Leaves elliptic-lanceolate, entire, acute at each end, smooth. Nut roundish, furrowed. (Smith.) "Native of the Molucca Isles. A large and lofty tree, the wood of which is hard and heavy; lasting long under water. Leaves 6in. or 8 in. long, and 3 in. broad, on short stalks, with 8 or 10 irregular lateral veins. Acorns short and roundish, furrowed in their upper part; the cup short, warty. By Rumphius's account, there seem to be more species than one comprehended under the chapter above cited; but he does not give us sufficient marks to define them specifically." (Smith in Rees's Cycl.)

Q. turbinata Blume Fl. Jav., t. 18.; and our fig. 1850. The top-shaped-cupped Oak. Leaves oblonglanceolate, sharp at both ends, sharply serrated towards the apex, glabrous. Cups top-shaped. A

The first 22 of the following oaks are described and figured in Humboldt and Bonpland's magnificent work on the plants of Mexico, entitled Plante Equinoctiales. 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. xalapensis Humb. et Ponp. Pl. Equin., t. 75., and our fig. 1852., Michx. N. Amer. Syl., 1. 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 flowers 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 Sphagnum], be sent to England.

glaucescens Humb. et. Bonp. Pl. Equin., t. 78., and our fig. 1853., Michx. N. Amer. Syl., p. 111. Leaves on short footstalks, wedge-shaped, obovate; entire at the base; slightly repand and
