ARBORETUM AND FRUTICETUM. 



PART HI, 



above, and yellowish beneath. The flowers are disposed in two or three cottony spikes at the ter- 

 mination of the branches. 



Q. concentrica Lour. Coch., 2. p. 572., Willd. Sp. PL, 4. p. 427., N. Du Ham., 7. p. 153., Smith in 

 Rees'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; with 

 ascending 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 cupg 

 short and lax, marked externally with several parallel circular furrows. 



Q. aciita Thunb. Jap., 175., Willd. Sp. PI., 4. p. 429., N. Du Ham., 7. p. 154., Smith in Rees's 

 Cycl., No. 17., has the leaves oblong, entire, and terminating in a sharp cuspidate point; rounded 

 at 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. 4ol., N. Du Hani., 7. p. 155., Smith in Rees's 

 Cycl., No. 25., has the leaves oblong, serrated, velvety, and downy beneath, when young, with parallel 

 veins. The trunk of this oak is divided into alternate, and rather knotty, brandies, which are of a 

 greyish colour, with white spots. Found on the mountains of Japan. 



Q. glauca Thunb. Jap., 175., Banks lc., Kaunpf, t. 17., Willd. Sp. PI., 4. p. 427., N. Du Ham., 7. 

 p. 159., Rees's Cycl., No. 21. ; Kas no Ki, Ktempf. Amcen., p. 816. ; has the leaves obovate, pointed, 

 serrated towards the extremity, and glaucous beneath. The nuts are roundish and pointed ; and 

 the calyx, which is shallow, is marked with concentric lines. Kaempfer calls this oak an " ilex, with 

 short thick acorns, of which there are two kinds." Thunberg found it near Nagasaki, in Japan. He 

 describes 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.annulata, Q. Phulluta Don. (See p. 19*22.) 



Q. cuspidata Thunb. Jap., 176., Willd. Sp. PI., p. 430., N. Du Ham., 7. p. 159., Smith in Rees's 

 Cyc!., No. 24. ; Sui, vulgb Ssi no Ki, Ktempf. Amcen., 816. Leaves ovate, pointed, serrated, smooth. 

 Calyx prickly. (Thunb.) Ksempfer calls this " Mgus fblio Fraxini," a beech, or beech-like oak, with 

 the leaves of an ash : but Thunberg describes it as only differing from Q. cocci'fera in its leaves being 

 cuspidate, 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. 



Q.dentdta Thunb. Jap., 177., Willd. Sp. PI., 4. p. 45'2., N. Du Ham., 7. p. 180., Rees's Cycl., 

 No. 26. ; Koku, KeEmnf. 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 are 

 soft to the touch, very lax and pliable, velvety on the upper surface, and covered with a very white 

 cottony down beneath. Kannpfer calls this tree the white ilex, and says that the wood is also 

 white. 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 have 

 been 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 ; exterior 

 ones 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 of 

 Castanea vtsca, and is probably the C. chine"nsis of Sprengel, with 1-seeded fruit. C. vesca is a very 

 common tree in the north of China, with fruit always 2 3-seeded, and very like those of Europe; and 

 the Chinese deny that there is any other species. 



Q. obovuta Bunge Mem. Acad. Scien. Petersb., 2. p. 136. Leaves obovate, nearly sessile, thickly 

 sinuated ; lobes round, quite entire, covered with rough dots above ; tomentose beneath, as are the 

 young 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 native 

 of mountainous places near Pekin ; flowering in March and April. Bunge observed a third species, 

 on the mountains in Pan-Schan, very similar to Q. mongolica Fisch. (see p. 1932.;; but nothing 

 certain.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. sundaica Blume Fl. Jav., t. 2. and 3. ; and our figs. 1833. and 1834. The Sunda Oak. Leaves 

 elliptic, 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, with 

 smooth bark. It is not unfrequent in the woods of Western Java, in low grounds, and on the
