10-14 cm - m diameter; scales strongly corky-thickened on 

 the back ; acorn ellipsoid or somewhat ovoid, about 12-15 mm. 

 long. 



J£j oblongifolia is nearest related to Q grisea but differs 

 in the glabrous leaves, and larger size of the tree.

A tree 9-12 m., or rarely 20 m. high with a trunk 6-12 dm. 

 in diameter. Bark of the trunk dark brown, deeply furrowed 

 and scaly, that of the branches reddish brown with numerous 

 lenticels, the young branchlets somewhat stellate : buds 

 brown, puberulent : petioles 2-5 mm. long: leaf-blades lan- 

 ceolate, ovate-lanceolate or oblong-lanceolate, thick and firm, 

 rounded, truncate or cordate at the base, acute or acuminate 

 and spinulose-tipped at the apex, entire or with a few sinuate 

 spinulose-tipped teeth, pale bluish or yellowish green and 

 shining above, paler and duller beneath, perfectly glabrous 

 on both sides or slightly stellate and puberulent when young, 

 2-7 cm. long: cup sessile, hemispheric, about 10 mm. in 

 diameter ; scales thin, scarcely thickened on the back, 

 round-ovate, obtuse, light brown, puberulent and stellate- 

 ciliate on the margin; acorn elongated-ovate, acute, 15-20 

 mm. long and 8 mm. in diameter, light brown and somewhat 

 striate, puberulent when young. 



Specimens with entire leaves much resemble j£. oblongi- 

 folia as to the leaves, but the species is easily distinguished 

 in fruit by the thin rounded cup-scales. From J^. Tounicyi,
