QUERCUS GLABRA 



Quercus glabra, Thunberg, Fl.Jap. 175 (1784); Franchet et Savatier, Enum. Fl. Jap. i. 447 (1875); 



Masters, in Gard. Chron. xiv. 784, fig. 153 (1880). 

 Pasania glabra, Oersted, in Kjoeb. Vidensk. Medd., 1866, p. 81 ; Shirasawa, Icon. Ess. Forest. Japon, 



text 61, t. 32, figs. 14-24 (1900); Schneider, Laubholzkunde, i. 160, fig. 95 (1904). 



A small tree with smooth bark. Young branches glabrous. Leaves (Plate 

 338, Fig. 50) coriaceous, persistent for two or three years, 4 to 5 in. long, 1 to i| 

 in. broad, lanceolate or elliptical, tapering at the base and prolonged as a narrow 

 wing on each side of the petiole; apex acute or contracted into a short acumen, 

 rounded at the tip ; margin entire, revolute ; upper surface shining, glabrescent ; 

 lower surface pale, glabrous, with numerous shining minute dots ; lateral nerves 

 about ten pairs, dividing and looping before reaching the margin ; petiole glabrous, 

 \ to f in. long. 



Fruit (section Pasania) ripening in the second year, grouped in threes and 

 numerous, but only a few developing, on an erect spike about 4 in. long ; acorn 

 ovoid, about an inch long, pointed, glabrous, surrounded at the base by a shallow 

 cupule, \ in. in diameter, covered with appressed grey tomentose ovate acuminate 

 scales. 



Q. glabra is a native of Japan, and was introduced 1 into cultivation in 

 England in 1842, when plants were raised in the Tooting and Epsom Nurseries. 

 We have not been able to separate as distinct var. latifolia 2 introduced by Maries 

 in 1877. This species does not appear to be quite so hardy as Q. acuta, and 

 remains a large bush, often seen in gardens in the south and west of England, and 

 in Ireland, where it ripens fruit. 8 There are specimens in the oak collection at 

 Kew. (A. H.) 



QUERCUS CUSPIDATA 



Quercus cuspidata, Thunberg, Fl. Jap. 176 (1784); Franchet et Savatier, Enum. PI. Jap. i. 449 

 (1875); Masters, in Gard. Chron. xii. 232, f. 38 (1879); Skan, in Journ. Linn. Soc. (Pol.) xxvi. 

 510 (1899). 



Pasania cuspidata, Oersted, in Kjoeb. Vidensk. Medd., 1866, p. 81 ; Shirasawa, Icon. Ess. Forest. Japon, 

 text 62, t. 34, figs. 1-13 (1900); Schneider, Laubholzkunde, i. 160 (1904). 



A large tree. Bark smooth on young stems, deeply fissured on old trunks. 

 Young branchlets glabrescent. Leaves (Plate 338, Fig. 51) coriaceous, per- 

 sistent two or three years, 2 to 3 in. long, f to 1 in. broad, elliptical ; base tapering 



1 Loudon, Gard. Mag. xviii. 17, 41 (1842). Gay, in Bull. Soc. Bot. Frantt, v. 32 (1858), mentions a small plant at 

 Verrieres in 1858 ; but this is not referred to in Hortus Vilmorinianus, published in 1906. 

 s Veitch, Cat. Trees and Shrubs, 1881-82, p. 22, and Hortus Veitchii, 405 (1906). 

 3 It ripened fruit in 1852 at Bishopstoke, Hants, according to Gardeners' Chronicle, 1852, p. 695.
