 May and November 1907 (No. 540; tree 6-12 m. tall, girth 1-2 m.); 

 Changyang Hsien, woods, alt. 1300 m.. May 1907 (No. 3640; tree

 Western Szech'uan: Chien-chi Hsien, summit of Fei-yueh-ling, 

 alt. 3000 m., May 1908 (No. 3625; bush 2.5 m. high) ; without locality, 

 alt. 2300 m., July 1903 (Veitch Exped. No. 4504; tree 10 m. tall). 



This is not a common tree in western Hupeh or Szech'uan, but is scattered over a 

 wide area. It never attains a large size. The crown is dense and flattened-oval in 

 outline. The leaves are coriaceous and shining green above and persist for two or 

 three seasons. They vary slightly in size and are frequently quite entire and the 

 under side of mature leaves is either quite glabrous or clothed with a short, curled 

 gray pubescence. The fruit is biennial and short-stalked in the axils of the leaves 

 immediately below the winter-bud of its current season's growth. The scales of the 

 cup are narrow and recurved and the cup resembles that of Q. cerris Linnaeus, but 

 is smaller.

 Quercus Dielsiana Seemen in Bot. Jahrb. XXIX. 291, fig. 2 (1900). 



Western Szech'uan: Wen-ch'uan Hsien, valley of Min River, 

 thickets, alt. 1500 m.. May 26, 1908 (No. 3628; bush 2 m.); " Tsa- 

 ku-lao", A. von Rosthorn (No. 2533, type of Q. Dielsiana). Shensi: 

 " Lao-y-san " and " Kin-qua-san," 1897, G. Giraldi; " Ta-hua-shan," 

 December 29, 1913, F. N. Meyer; south of Sian Fu, mountains near 

 " Nan-tu-tchu," January 21, 1914, F. N. Meyer(No. 1692). 



In warm semi-arid regions of the Min River valley this Oak is a common shrub, 

 but Wilson did not meet with it elsewhere. Meyer observes that it grows on sterile 

 mountain slopes in Shensi and is semi-evergreen, the leaves persisting through the 

 winter. The fruit is biennial; the scales of the cup are recurved and the cup re- 

 sembles that of Q. spathulata Seemen. The leaves are membranous with spinescent 

 teeth.
