leaves are oval-oblong or elliptic-lanceolate, entire and wedge-

the edge, ending in an acute or prolonged point, mostly entire. 
Young leaves silky-downy, mature, smooth on both surfaces; 
mid-rib sometimes downy above; glaucous beneath; of a thin 
and delicate texture. Stipules half-heart-shaped, or ear-shaped, 
sometimes small and nearly entire, sometimes half an inch long 
and more or less sharply toothed. 
Female ament cylindrical, one or two inches long, somewhat 
crowded, on a short stalk invested with a few cucullate, silky-
