shLirt trunk and lower limbs horizontal or declined, cliaracteristically 

 g-nurlfd and twisted. 



BARK — Lig-ht gray or nearly white, whence its name; broken by 

 shallow fissures into long, irregular, thin scales which readily flake 

 off. On snme trees ridges broken into short oblongs giving a rougher 

 appearance to bark. Bark up to 2 inches thick in older trees ; inner 

 bark light. Tlie bark is rich in tannin, is of medicinal value and is used 

 in tanning. 



TAVIGS — Of medium thickness, greenish -reddish to gray, smooth, 

 sometimes coven-d with a bloom. LEXTICELS— forming conspicuous, 

 light-colored, minute, ruunded, raised dots. LEAVES — frequently remain-

COMPARISOXS — The White Oak is the most common of the White 

 Oak group. Its light flaky bark resembles that of several other oaks. 

 It is readily distinguished frum the Swamp White Oak by absence of 

 peeling of bark on >'0ung brandies and by its larger and more 

 pointed buds; from the Post Oak by absence of greenish down on 

 twigs and by generally larger, narrower buds; from the Chinquapin Oak 

 by its blunt buds: from the Dwarf Chinquapin Oak by its larger stature, 

 larger t^vigs and buds.

 sometimes forming nearl\' pure fore .^ts. ijupljec and Ontario ; south to 

 the Gulf of Mexico; west to Minntsola. X'ebraska, Kansas, Arkansas and 

 Texas. 



IN XTEW EX^GLAND — Maine — southern sections; X^ew Hampshire — most 

 abundant eastward; in the Connecticut valley confined to the hills in 

 the immediate vicinity of the river, extending- up the tributary streams 

 a short distance and disappearing entirely before reaching the mouth 

 of the Passumpsic; Vermont- — common west of the Green Mountains, 

 less so in the southern Connecticut valley; Massachusetts, Pihode Island 

 — common. 



IX^ COXXECTICUT — Common throughout. 



AA'OOD — Strong-, very heavy, hard, tough, close-grained, durable, light
