Leaves slender, stiff, slightly twisted, pale green and somewhat glaucous, 6'-9' 

 long, marked by 10-12 rows of large stomata on each face, deciduous during their 

 third year. Flow- 

 ers opening from 

 the middle of March

 coming light reddish 

 brown, with thin 



scales rounded at the apex and armed with short stout straight or reflexed prickles, 

 opening irregularly and discharging their seeds during the autumn and winter, and 

 usually persistent on the branches for another year; seeds rhomboidal, full and 

 rounded, \' long, with a thin dark brown rough shell blotched with black, and pro- 

 duced into broad thin lateral margins, encircled to the base by the narrow border of 

 their thin pale brown lustrous wings broadest above the middle, 1' long and about 

 \' wide. 



A tree, generally 80-100 high, with a tall straight trunk usually about 2 but occa- 

 sionally 5 in diameter, short thick much divided branches, the lower spreading, the 

 upper ascending and forming a compact round-topped head, and comparatively slender 

 glabrous branches brown tinged with yellow and covered with a glaucous bloom dur-

 the shores of the Gulf of Mexico, and through eastern Texas to the valley of the
