 generally apiculate at apex, truncate rounded or abruptly wedge-shaped at base, 

 entire, sinuate or serrate- dentate with spreading, rigid, bristle- pointed teeth, 

 stellate-pubescent at first, soon glabrous dark green above and somewhat paler 

 and more yellowish beneath ; slightly if at all concave beneath ; petioles rather 

 slender hoary pubescent at first and usually more or less so at maturity ; the 

 cilliate stipules caducous ; Staminate flowers in hairy aments 2-4 in. long ; calyx 

 glabrous with broad cilliate lobes ; stamens 3-6, exserted, with slender filaments 

 and yellow apiculate anthers. Pistillate flowers are subsessile, with hoary 

 tomentose peduncle and involucral scales ; styles often more than three, slender 

 and recurved. Fruit ripens in the autumn of the second year, sessile on short 

 peduncles, acorns solitary or few together, with slender taper-pointed chestnut- 

 brown and often striated thin-shelled nut, |-1| in. long and scarcely 1 in. 

 broad at base, sericio-tomentose within ; cup thin*, tnrbinate, varying from $ to 

 1 in. deep, or sometimes shallow and covered with thin light brown closely

The specific name, Wislizeni, is given in compliment to Dr. F. A. Wislizenus, an 

 early botanical explorer who gathered the type specimens on which the species 

 was founded. 



This beautiful tree attains the height of 75 or 80 ft. (24 m.), with 

 round wide close top of strong spreading branches and dense dark 

 green foliage. The trunk, which is generally short, is occasionally ."> 

 or 6 ft. (1.50 m.) in diameter, and its bark is of a dark brown color, 

 ridged longitudinally and covered with firm closely appressed scales. 

 It is a handsome tree and adds not a little to the charms of the land- 

 scape scenery in the regions in which it abounds. 



HABITAT. California from Mount Shasta southward along the 

 foothills of the Sierra Nevada Mountains to the Tehachapi Mountains 

 and among the Coast ranges as far south as Santa Lucia Mountains. 

 In its tree form it is confined to the interior, back some distance from 

 the sea, being supplemented near the coast by the Quen-us agrifofni. 

 a tree of very similar aspect and with which it was at first confounded.
