4. Quercus Vreelandii sp. nov. 



JQuercns Gambelii Sargent, Silva N. Am. 8: 331, in part. 

 1895. 



A small shrub, 1-1.5 m. high. Bark of young branches 

 brown, puberulent ; that of the older branches and trunks ashv 

 gray: bud-scales brown, thin, puberulent on the margins: 

 petioles 5-10 cm. long, puberulent : leaf-blades 5-7 cm. long, 

 obovate, deeply lobed about two-thirds to the midrib, thick, 

 firm ; lobes rounded, the larger often lobed or sinuate ; upper 

 surface slightly stellate, soon glabrate, bright green and 

 rather dull ; lower surface slightly paler and somewhat 

 brownish and puberulent : fruit subsessile : cup very shallow, 

 covering one-fifth or one-sixth of the acorn ; scales ovate 

 and very corky on the back: acorn barrel-shaped or slightlv 

 ovoid, obtuse, about 15 mm. long, light brown. 



In leaves this species most resembles J<K Gambelii ; the 

 upper surface is, however, brighter green, and the leaf is 

 much firmer and therefore more like that of J^. Gunnisoiiii 

 in texture. It is more obovate in outline than in that species, 

 the fruit is smaller and the cup is very shallow ; in the 

 latter respect it differs from all the related species. It is also 

 a smaller and more scraggling bush. The leaves are light
