1300 The Trees of Great Britain and Ireland 



other Californian evergreen oaks with spiny leaves; as it extends northwards 

 into southern Oregon, southwards to Mt. San Pedro Martir in Lower California, 

 and eastward to the high mountains of southern Arizona, New Mexico, and the 

 province of Sonora in Mexico. It yields valuable wood, which is used in the 

 manufacture of waggons and agricultural implements. 



The only specimens which we have seen in cultivation are plants at Kew, 

 2 to 3 ft. high, raised from acorns obtained from Meehan in 1904. There are also 

 small plants at Coombe Wood. (A. H.) 



QUERCUS GLABRESCENS 



Quercus glabrescens, Bentham, PL Hariw. 56, 348 (excl. syn. Q. spkndens, N^e) (1839) ; De Candolle, 

 Frod. xvi. 2, p. 34 (1864); Liebmann, Chines Am. Trap. t. 39 (1868); Hemsley, Biol. 

 Centrali-Amer. Bot. iii. 172 (1882). 



A small tree. Bark peeling off in thin quadrangular scales. Young branchlets 

 slender, with scattered stellate pubescence. Buds minute, globose, surrounded by 

 persistent linear pubescent stipules. Leaves (Plate 339, Fig. 67) coriaceous, 

 persistent two years, 2 to 2\ in. long, f to i in. broad, obovate-oblong, rounded or 

 sub-cordate at the base, acute at the apex ; margin thickened, revolute, with three to 

 six pairs of gland-tipped small teeth above the middle ; lateral nerves seven or 

 eight pairs ending in the margin ; upper surface dark green, shining, pubescent on 

 the midrib, elsewhere glabrescent ; lower surface yellowish, with scattered stellate 

 pubescence ; petiole stout, \ in. long, stellate-pubescent. 



Fruit ripening in the first year, two or three on a pubescent peduncle ; acorn 

 ovoid, surrounded in its lower half by a hemispherical cupule, covered with 

 appressed ovate pubescent scales. 



This species is a native of the mountains of southern Mexico, and was first 

 described by Bentham, from specimens collected by Hartweg, the locality being 

 unknown, but supposed to be near Real del Monte. Liebmann afterwards, in 1841 

 and 1842, found it growing on the peak of Orizaba at 8000 to 9000 ft. altitude, and 

 also at Chinantla, Cuesta de Lachopa, and Cerra Leon. It appears to be a small 

 evergreen tree, but its dimensions are not stated. Amongst Liebmann's specimens 

 at Copenhagen, there is an entire-leaved variety of this species, which I have not 

 seen. 



This appears to have been one of the trees introduced by Hartweg, who sent 

 all his specimens of oaks, with acorns of some of the species, to the Horticultural 

 Society ; but Gordon,^ in his account of the new plants introduced into the Chiswick 

 Garden in 1840, states that the acorns of this species were presented by Mr. 

 Strangways. 



The only tree which survives, so far as we know, is growing in the Botanic
