the depth of the lobing, the amount and character of hairiness 

 of the leaves, and in the characters of the acorns, these char-

Scrub Oak. (Quercus pungens) 



There are several species of Scrub Oaks, a few of which 

 are quite characteristic and tolerably easily recognized. All 

 of them are important as foiage plants, since they are browsed 

 extensively wherever they grow. 



The Shin-Oak or Shinry (Quercus havardii) is a low 

 deciduous-leaved shrub, rarely over 3 feet high and with a very 

 large acorn, that covers relatively large areas of sand hills in 

 the southeastern corner of the State. As an economic plant 

 for sandy land that is otherwise almost valueless this little oak, 

 with its large acorn, will probably prove of considerable value. 

 Quercus undulata is another shrubby species with small bluish- 

 green leaves and small acorn, that occurs in the foothills of 

 the higher mountains and to some extent along water courses 

 in the higher plains. A near relative of this species, Quercus 

 fendleri, is a somewhat larger shrub, often 8 to 10 feet high, 

 that reaches slightly farther up into the mountains. Other 

 shrubby species are Quercus rydbergiana, Q. pungens, and 

 probably Q. turbinella.
