2. Quercus submollis sp. nov. 



Size of the tree unknown. Bark of young branches light 

 brown, roughened with numerous lenticels, finely pubescent ; 

 that of the older branches light ashy gray, sometimes almost 

 white and shining : petioles about i cm. long, densely pubes- 

 cent with brownish hairs : leaf-blades narrowly obovate in out- 

 line, deeply pinnately lobed with the rounded sinuses extend- 

 ing two-thirds to the midrib : segments rounded, rarely lobed ; 

 upper surface green, sparingly stellate, or glabrous and shin- 

 ing in age ; lower surface brownish, pale, densely and softly 

 pubescent, veins rather prominent: bud-scales light brown, 

 thin and pubescent : fruit sessile : cup depressed-hemispheric, 

 about 15 mm. in diameter ; scales oblong, rather thin, scarcely 

 at all thickened on the back, puberulent ; acorn short barrel- 

 shaped, obtuse, 12-15 mm - long, light brown. 



This species is closely related to the next following and 

 hard to distinguish without the fruit. This is quite different ; 

 the scales lack the corky thickening common in this group 

 of oaks and this character together with the dense and soft 

 pubescence of the lower surfaces of the leaves, easily distin- 

 guish it from J£. Gambclii.
