(2IO) 



A shrub 3-5 m. high. Bark of young twigs light brown 

 and puberulent ; that of the older branches and trunk gray : 

 bud-scales brown, puberulent: petioles about 1 cm. long, 

 puberulent : leaf-blades broadly obovate in outline, lobed one- 

 half or two-thirds the distance to the midrib, thinner than in 

 the preceding ; upper surface glabrate, green, not very 

 glossy; lower surface only slightly paler, puberulent or 

 nearly glabrous ; lobes rounded : fruit subsessile : cup hemi- 

 spheric or somewhat turbinate ; acorn ovoid, acute, half en- 

 closed in the cup, about 15 mm. long, light brown. 



The leaf form is mostly like that of ££. Gunnisonii but the 

 blade is usually broader, thinner, decidedly obovate, and the 

 acorns are much smaller and acute. From the preceding 

 it differs in the less glossy and less deeply lobed leaves and 

 the form of the fruit. The leaves when unfolding are pink- 

 ish yellow. It is much less common than the preceding, to 

 which it is closely related ; some intermediate forms are 

 found, although they are rare.
