Quercus reticulata^ a large tree in the canons of the Sierra Madre of Mexico,^ rarely grows more 

 than thirty feet tall on the mountains of southern Arizona and New Mexico or produces a trunk that 

 exceeds a foot in diameter^ and is usually shrubby in habit and sometimes only a few feet high. The 

 bark of the trunk is about a quarter of an inch thick^ and is dark or light brown and covered with 

 small thin closely appressed scales. The branchlets, which are stout and marked with pale lenticels^ are 

 coated, when they first appear, with thick fulvous tomentum, and during their first winter are light 

 orange-colored and more or less thickly clothed with pubescence^ ultimately becoming ashy gray or 

 light brown. The winter-buds are ovate or oval, often accompanied by the persistent stipules of the 

 upper leaves, about an eighth of an inch long and covered by thin loosely imbricated light red scales 



The leaves are revolute in the bud, broadly obovate, usually cordate or 

 occasionally rounded at the narrow base, obtuse and rounded or rarely acute at the apex, repandly 

 spinose-dentate above the middle or only toward the apex with slender teeth, and entire below ; when 

 they unfold they are coated with dense fulvous tomentum, and at maturity are thick, firm and rigid, 

 dark blue and covered with scattered stellate hairs on the upper surface, paler and clothed with thick 

 fulvous pubescence on the lower surface, from one to five inches long and from three quarters of 

 an inch to four inches broad, with stout midribs slightly raised on the upper side and remote primary 

 veins running to the points of the teeth or arcuate and united within the slightly revolute margins, 



ciliate on the margins. 



coarse conspicuous reticulate veinlets, and stout petioles about a quarter of an inch in length. 



The 



stipules are linear, scarious, light brown, pubescent, and caducous, or those of the last leaves 

 sometimes persist on the branches until the opening 



of the buds of the following season. 



The 



flowers appear in Arizona in May and June, and are borne, the staminate in short tomentose aments 

 from the axils of the leaves of the year, the pistillate in spikes on elongated peduncles clothed, like 

 their involucral scales, with hoary tomentum. The calyx of the staminate flower is light yellow and 

 coated with pale hairs, and is divided into from five to seven ovate acute segments shorter than 

 the stamens, which are composed of slender filaments and smooth ovate emarginate glabrous yellow 

 anthers. The stigmas of the pistillate flowers are dark red. The acorns are borne usually in many- 

 fruited spikes or occasionally in pairs or rarely solitary, on slender hirsute or glabrous peduncles 

 from two to five inches in length and persistent on the branches for one or two years ; the nut is 

 oblong, rounded or acute at the pilose apex, broad at the base and about half an inch long, with deep
