310 QUERCUS 



rusty down ; often a shrub spreading by underground suckers. Leaves of 

 firm texture, 3 to 5 ins. long, 2 to 3 ins. wide ; obovate, tapered at the base 

 with three to six deepish lobes at each side ; the lobes oblong, often with two 

 or three undulations or minor lobes near the apex ; upper surface dark glossy 

 green, covered (at least when young) with starry down ; pale, dull, and more 

 conspicuously downy beneath ; stalk slightly downy, j to ^ in. long. Acorns 

 stalkless or short-stalked, f in. long. 



Native of the eastern slopes of the Rocky Mountains in Colorado, Utah, 

 Nevada, etc., up to 7000 ft. elevation. 



Q. GLABRA, Thunberg. 



An evergreen small tree up to 30 ft. high, usually a shrub in this country, 

 of spreading habit ; young shoots smooth. Leaves smooth, narrowly oval or 

 oblanceolate, tapered at both ends, blunt-pointed, entire, of hard, leathery 

 texture ; 3^ to 6 ins. long, I to 2j ins. wide ; glossy yellowish green above, 

 dull and greyish beneath, nine to eleven veins on either side the midrib ; 

 stalk \ to i in. long. Acorns produced in triplets on spikes 2 to 3 ins. long, 

 but only an occasional acorn attains to full size, for which it requires two 

 seasons ; it is then about I in. long, \ in. wide, pointed at the apex, and in 

 shape very like the modern bullet. The cup is about \ in. deep. 



Native of Japan ; introduced in the first half of the nineteenth century, 

 but still somewhat rare. It is a distinct and handsome evergreen, most nearly 

 resembling Q. acuta, but differing in the more tapered base of its leaves and 

 in its glabrous character. When very young the leaves have a scaly covering, 

 but in Q. acuta they are distinctly woolly. It is best adapted for the milder 

 parts of the country, but has produced perfect acorns at Kew. 



O. GLANDULIFERA, Blume. 



A deciduous tree up to 30 or 40 ft. high, of elegant habit ; young shoots 

 with silky, appressed, and forward-pointing hairs. Leaves obovate or narrowly 

 oval, 2 to 7 ins. long, i to 7\ ins. wide ; tapered at both ends, with six to 

 twelve incurved, gland-tipped teeth at each side, and eight to fourteen pairs of 

 parallel veins running out to the apex of the teeth ; dark green above, greyish 

 beneath, both surfaces white with appressed silvery hairs when quite young, 

 much of which falls away from the upper one ; stalk \ to \ in. long. Acorns 

 small, solitary, or several on a short stalk ; cup shallow. 



Native of Japan, Corea, and China ; introduced in 1893 by Prof. Sargent. 

 It varies in size and shape of leaf on different trees ; the leaves of one form 

 at Kew are only \ to i^ ins. wide. All the forms promise to make shapely 

 specimens. The species thrives remarkably well in the vicinity of Boston, 

 Mass. 



Q. GROSSESERRATA, Blume. 



A large deciduous- .tree, 80 to 100 ft. high ; young shoots irregularly 

 furnished with pale warts, but not downy. Leaves obovate, 4 to 9 ins. long, 

 2 3T t 5^ ms> wide ; tapered to a pair of auricles at the base, pointed at the 

 apex, ten to fifteen teeth on each margin, the largest from \ to f in. deep, 

 triangular, and again toothed ; dark, rather glossy green above, pale beneath, 

 smooth except on the midrib and veins, which are more or less downy on 

 both surfaces ; stalk \ to \ in. long, smooth. Acorns one to three on a short 

 stalk, about one-third enclosed in the hemispherical cup (not yet produced in 

 this country). 



Native of Japan ; introduced to Kew by Prof. Sargent in 1895. Although 

 it appears to be quite hardy in this country, this oak does not thrive so well
