Western Szech'uan: southeast of Tachien-lu, alt. 2000-2600 m., 

 October 1910 (Nos. 4583, type 4281, seeds only). 



A well-marked species distinguished by its annual fructification from all Chinese 

 Oaks with spinescent leaves except Q. semicarpifolia Smith. The latter has a more 

 or less persistent felt of yellow-brown or gray-brown hairs on the under side of the 

 leaves, a shallow saucer-shaped cup with fewer, triangular-lanceolate to lanceolate 

 scales and is loosely fringed round the rim ; the acorn is more or less globular. The 

 cup of our new species somewhat resembles that of Q. Ilex Linnaeus, but is much 

 smaller in every way. In arid parts of the Tung River valley and in those of its 

 tributaries in western Szech'uan between 1300 and 2600 m. altitude this new Oak 

 is very common and covers large areas in the form of scrub from 0.3 to 1 m. high. 

 Under more favorable conditions and on the margins of woods it is a small tree 

 with rather slender branches which form an oval or flattened, dense crown. It is 

 named for the late Captain W. J. Gill, who in 1877 made an extended tour 

 through western China. He was one of the first travellers to visit Tachien-lu and 

 in his book (The River of Golden Sand) frequent references to the "Holly-leaved 

 Oak" of western Szech'uan are made.
