1232 The Trees of Great Britain and Ireland 



and northern Arkansas. It is comparatively rare in the east, being most abundant 

 in the basin of the lower Ohio and in the State of Missouri, and attains its largest 

 size in southern Indiana and Illinois. Ridgway says that with the possible 

 exception of Q. alba it is the most abundant and generally distributed species in 

 Wabash Co., 111., where it is the most slender of all the oaks ; trees 100 ft. high 

 and 50 ft. to the first branch being only 6 to 7 ft. in girth. On poorer soil, how- 

 ever, where it is more abundant, it does not usually much exceed half this size. 

 According to Sargent, it is occasionally planted in the northern states, being hardy 

 as far north as Massachusetts. 1 



Although introduced into cultivation by John Fraser in 1786, it was a rare 

 species in Loudon's 2 time, and no old trees exist, so far as we know, in this country. 

 There are, however, two at Bayfordbury, supposed to have been planted with other 

 American oaks in 1836, one of which measured 52 ft. high and 4 ft. 8 in. in girth in 

 1909 ; the other was 40 ft. by 4 ft. 9 in. 



At Tortworth there is a healthy tree, about 35 ft. high. There is a well-grown 

 tree in Mr. Young's nursery at Milford, near Godalming, which in 1909 was 60 ft. 

 by \\ ft., with a bole 20 ft. long. We have also identified trees of this species 

 growing at Westonbirt, Kew, Beauport, Aldenham, and Yattendon Court near 

 Newbury. (H. J. E.) 



QUERCUS LEANA 



Quercus Leana, Nuttall, Sylva, i. 13, t. 5 bis (1842); Hill, in Bot. Gaz. xix. 171 (1894); Sargent, 



Trees N. Amer. 252 (1905). 

 Quercus imbricaria x coccinea, Engelmann, in Trans. St. Louis Acad. iii. 539 (1877). 

 Quercus imbricaria x velutina, Sargent, Silva N. Amer. viii. 176, t. 434 (1895). 



A large tree. Young branchlets stout, reddish, with scattered stellate 

 pubescence. Leaves (Plate 334, Fig. 10) oblong, lanceolate, 5 to 7 in. long, 2 to 

 2\ in. wide, with three to five pairs of short triangular bristle-pointed lobes, which 

 in some cases are minute or absent ; acute and mucronate at the apex, rounded or 

 cuneate at the base ; upper surface shining, dark green, with scattered, stellate, 

 mostly deciduous pubescence ; lower surface duller and paler, with persistent 

 stellate pubescence, scattered between the veins, but densely crowded in tufts in 

 the axils and in bands along the midrib ; venation similar to that of Q. heterophylla ; 

 petiole, ^ to 1 in. long, with scattered stellate pubescence. 



Fruit sub-sessile or on a short stalk, usually solitary ; acorn sub-globose, enclosed 

 to near the middle in a turbinate hemispherical cupule resembling that of Q. velutina, 

 which is covered with ovate loosely imbricated pubescent scales. 



1 Q. laurifolia, Michaux, a more southerly species, is closely allied to Q. imbricaria, and is figured in Plate 339, Fig. 74. 

 It is said to have been introduced in 1786 ; but is apparently not in cultivation at present, and is probably unsuitable for our 

 climate. 



J Loudon only mentions one tree, which was growing in the Horticultural Society's garden at Chiswick.
