A shrub 1-3 m. high, scarcely forming thickets. Bark 

 of young branches brown, puberulent ; that of the older 

 branches and trunks gray : bud-scales brownish, puberulent : 

 petioles 3-6 mm. long, puberulent : leaf-blades oval or elliptic 

 in outline, lobed about half way to the midrib, firm, 3-7 

 cm. long ; lobes obliquely triangular, acute, mucronate but 

 not spinulose tipped ; upper surface sparingly stellate or gla- 

 brate, pale bluish green and shining ; lower surface light 

 brownish, stellate-puberulent, strongly veined and reticulate : 

 fruits 2-3 together on a peduncle : cup hemispheric, cover- 

 ing about one-third of the acorn, 10-12 mm. broad; scales 

 ovate and much corky-thickened on the back : acorn barrel- 

 shaped, obtuse, or somewhat ovoid and acute, 15-18 mm. 

 long, light brown. 



J^j Fendlcri is of about the same size as most of the species 

 of the 4L Gambelii group but I have not found it forming 

 any thickets. It is more scraggly. The leaves remain longer 

 on the shrub, but are not remaining till next spring. They 

 are much paler and resemble those of «J<L- undulata in texture 

 but are much deeper lobed. It grows on barren hills at an 

 altitude of 1000-2500 m.
