2. Q. garryana Dougl. OREGON OAK. Tree 25 to 55 feet high, the trunk 

 11/2 to 5 feet in diameter and dividing into wide-spreading limbs which sup- 

 port a broad rounded crown 30 to 60 feet in diameter"; trunk bark white, 

 thin (1/2 inch thick), smoothish, but on typical trunks superficially fissured 

 into longitudinal bands which are transversely checked into small squarish 

 scales 1 inch or less in diameter; leaves 3 to 4 or 6 inches long, l 1 /^ to 3 

 inches broad, dark lustrous green and subglabrous on the upper surface, rusty 

 or pale, finely pubescent and yellow-veined beneath, leathery in texture and 

 parted into 5 to 7, or rarely 9, lobes with mostly deep and often acute sinuses ; 

 lobes entire or with 2 or 3 coarse rounded unequal teeth; staminate catkins 

 hirsute ; stamens 4 to 6 ; pistillate flowers sessile or short-pedunculate ; acorns 

 maturing in first autumn ; cup saucer-shaped, 6 to 9 lines broad, with tubercu- 

 late scales; nut bulging beyond the small cup, typically subglobose but varying 

 to obovoid or subcylindric, although always rounded at apex, ^4 to l 1 /^ inches 

 long, % to 1 inch thick, its surface polished and shining. 



Coast Ranges : Santa Cruz Mts. ; Mt. Tamalpais, north slope ; mountain 

 slopes on both sides of Santa Rosa, Russian River and Ukiah valleys; abundant 

 on all the higher mountains from Ridgewood, Willits, Sherwood, Cummin gs, 

 Bell's Springs and Round Valley north to Siskiyou Co., mostly from 1,500 to 

 4,000 feet. Associated with Douglas Fir, Madrona and Black Oak (cf. Fig. 

 8) ; not in main Redwood Belt. Far north to Washington and British Columbia 

 where it is the only oak. Wood used for shipbuilding and interior finish in 

 Oregon. Also called Post Oak and Garry Oak. 



Var. semota Jepson n. var. Leaves pinnatifid, the sinuses rather sharp, 3 to 

 4 inches long, 1% to 2~y inches broad; cup shallow, scale tips thin, only slightly 

 or somewhat tuberculate at base; nuts oval, 10 to 13 lines long. (Folia pin- 

 natifida sinibus subincisis, 3 ad 4 poll, longa, 1% ad 2^ poll, lata; cupula 

 brevis, apicibus squamarum tenuibus, basi subtuberculatis ; glans ovalis, 10 ad 

 13 lin. longa). Southern Sierra Nevada from the Kaweah Basin (type loc. 

 5,000 feet) northward to Mariposa. Scarcely different save in size and here- 

 tofore referred by authors to Q. breweri.
