Leaves involute in the bud, lanceolate, often slightly falcate, acuminate and long-pointed at the 

 apex, gradually narrowed and cuneate at the base, finely glandular-serrate ; when they unfold 

 pubescent on the midribs above and sparingly villose below and on the margins, and at maturity 

 glabrous, light green on the upper surface, paler on the lower surface, from 1 to 1.2 decimetres 

 long, and from 1.2 to 1.5 centimetres wide ; petioles slender, pubescent early in the season, becom- 

 ing glabrous, from 8 to 10 millimetres in length. Flowers in slender densely villose aments, 

 terminal on leafy pubescent branchlets, their scales ovate, usually acuminate, thickly coated with 

 long shining matted white hairs more abundant on the inner surface ; staminate aments from 6 to 7 

 centimetres long, their scales broader than those of the pistillate aments ; stamens four or five, the 

 filaments covered with long white hairs ; pistillate aments from 2 to 7 centimetres long, the flowers 

 on slender glabrous pedicels 2 millimetres in length, ovate, gradually narrowed to the apex, 

 crowned with a nearly sessile two-lobed stigma. Fruit ovate, conical, pale brown, about 5 milli- 

 metres in length. 



A tree, from 18 to 22 metres high, with a trunk often from 1 to 1.5 metres in diameter, covered 

 with thick pale yellow-brown deeply furrowed rough bark, the surface sometimes separating into 

 long plate-like scales, large erect and spreading branches forming an open irregular head, and 

 slender branchlets light green and slightly pubescent when they first appear, becoming light 

 orange or yellow-brown and lustrous. Flowers in March. Fruit ripens in April and May.
