above, and yellowish beneath. The flowers are disposed in two or three cottony spikes at the ter-initiation of the branches.
Q. concintrica Lour. Coch., 2. p. 572., Willd. Sp. PI., 4. p. 427., N. Du Ham., 7. p. 153., Smith inRees’s Cycl., No. 10. Leaves lanceolate-ovate, pointed, incurved, entire. Calyx lax, very short,furrowed concentrically. {Willd.) A large tree, a native of the lofty forests of Cochin-China ; withascending branches, and comparatively few leaves, which are stalked, and smooth on both sides.The acorns are oblong-ovate, and borne on peduncles; the nuts are smooth, red, pointed; and the cupsshort and lax, marked externally with several parallel circular furrows.
Q. acuta Thunb. Jap. , 175., Willd. Sp. PI., 4. p. 429., N. Du Ham., 7. p. 154., Smith in Rees’sCycl., No. 17., has the leaves oblong, entire, and terminating in a sharp cuspidate point; roundedat the base ; glabrous above, but downy beneath when young. The branches of this oak are knotty,smooth, except near their extremities, which are downy. The under sides of the leaves are, also,covered with a ferruginous down, when young, as are the spikes of flowers. A native of Japan .
Q. serrdta Thunb . Jap,, 176., Willd. Sp. PI., 4. p. 431., N. Du Ham., 7. p. 155., Smith in Rees’sCycl., No. 25., has the leaves oblong, serrated, velvety, and downy beneath, when young, with parallelveins. The trunk of this oak is divided into alternate, and rather knotty, branches, which are of agreyish colour, with white spots. Found on the mountains of Japan .
Q. glaitca Thunb. Jap. , 175., Banks Ic., Kasmpf., t. 17., Willd. Sp. Pi., 4. p. 427., N. Du Ham., 7.p. 159., Rees’s Cycl., No. 21.; Kas no Ki, Kcempf Amcen ., p. 816.; has the leaves obovate, pointed,serrated towards the extremity, and glaucous beneath. The nuts are roundish and pointed; andthe calyx, which is shallow, ismarked with concentric lines. Kmmpfer calls this oak an “ ilex, withshort thick acorns, of which there are two kinds.” Thunberg found it near Nagasaki, in Japan . Hedescribes it as a very large tree, with spreading branches, somewhat resembling the ilex, or cork tree;but with very large, broad, pointed leaves, smooth above, and very glaucous or mealy, and feather-nerved beneath. Smith supposes it to be the same as his Q.annulkta, Q. Fhulldta Don. (Seep. 1922.)
Q. cuspiddta Thunb. Jap. , 176., Willd. Sp. PI., p. 430., N. Du Ham., 7. p. 159., Smith in Rees’sCycl., No. 24.; Sui, vulgb Ssi no Ki, Kcempf. Amcen., 816. Leaves ovate, pointed, serrated, smooth.Calyx prickly. {Thunb .) Kasmpfer calls this “ F&gus fblio Fraxini,” a beech, or beech-like oak, withthe leaves of an ash : but Thunberg describes it as only differing from Q. coccifera in its leaves beingcuspidate, and their teeth not spiny. The leaves are small, and very glabrous; and the acorns,which are as large as a common walnut, have bristly cups. A native of Japan .
if. dentdta Thunb. Jap. , 177., Willd. Sp. PI., 4. p. 452., N. Du Ham., 7. p. 180., Rees’s Cycl,No. 26. j Koku, Kcempf. Amcen., 816. Leaves ovate-oblong, obtuse, deeply toothed ; downy beneath.{Thunb .) A tree, with thick, erect, furrowed, knotty branches ; cottony at the summit of the tree.The leaves are produced in tufts at the extremity of the branches, on very short petioles: they aresoft to the touch, very lax and pliable, velvety on the upper surface, and covered with a very whitecottony down beneath. Ksempfer calls this tree the white ilex, and says that the wood is alsowhite. Thunberg states that it is a native of the hills of Japan .
The oaks of China have been enumerated, as far as they are known, in p. 177. The following havebeen described :—
Q. chinensis Bunge Mem. Acad. Scien. Petersb., 2. p. 135. Leaves ovate-oblong, elongated, acumi-nated, mucronato-serrate; hoary beneath. Cups axillary, twin. Scales lanceolate, hoary ; exteriorones squarrose, longer than the globose nut. A tree, a native of mountainous places in China ; flower,ing in April, and ripening its fruit the following year. It has exactly the habit and leaves ofCastanea vesca , and is probably the C. chinensis of Sprengel, with 1-seeded fruit. C. vesca is a verycommon tree in the north of China,with fruit always 2—3-seeded, and very like those of Europe ; andthe Chinese deny that there is any other species.
Q. obovdta Bunge Mem. Acad. Scien. Petersb., 2. p. 136. Leaves obovate, nearly sessile, thicklysinuated ; lobes round, quite entire, covered with rough dots above; tomentose beneath, as are theyoung branches. Fruit terminal, aggregate, sessile. Outer scales of the cup ovate-oblong, blunt,silky; inner ones elongated, linear, acute, bent back, longer than the roundish nut. A tree, a nativeof mountainous places near Pekin ; flowering in March and April. Bunge observed a third species,on the mountains in Pan-Schan, very similar to (2. mong61ica Fisch. (see p. 1932/); but nothingcertain^can be determined respecting it, from the imperfection of the specimens.
App. vii. Oaks of’Java, Sumatra , and the Molucca Isles, not yet
introduced.
Q. sunddica Blume FI. Jav., t. 2. and S.; and our figs. 1833. and 18S4. The Sunda Oak. Leaveselliptic, acuminate; narrowed towards the base ; glabrous above, somewhat glaucous beneath; veins
covered with down. Catkins solitary. A tree, attaining the height of 80 ft. and upwards,smooth bark. It is not unfrequent in the woods of Western Java, in low grounds, ana o
