green, since the gray-green or bluish-green leaves remain at- 

 tached to the stems until the leaves of the next year are well 

 developed. Besides the tree-like forms many shrubby species

 tensively by cattle, sheep, and goats. 



For decorative purposes perhaps the most important oak 

 is Silver-Leaved Oak (Quercus hypoleuca) of the southwest- 

 ern corner of the State. It gets to be a tree 30 feet high or more, 

 but is frequently found as a small shrub forming clusters. The 

 leaves are characteristic, being very thick and leathery, oblong 

 lanceolate, mostly without teeth though occasionally with a 

 few coarse ones near the apex ; yellowish green and smooth 

 above, denselv white woolly beneath.
