with white hairs, finally glabrous, quad rately-o vate and obtuse. 

 Leaves at first half-folded, the older ones flatter, oblong-orbicular, 

 truncate or subcordate at the base, obtuse or slightly twisted at 

 the apex ; margin slightly reflexed, slightly and rather remotely 

 glandular serrate-crenate or nearly or quite entire, youngest 

 leaves less obscurely crenate; surfaces at first, and especially 

 below, more or less furnished with white woolly adpressed hairs, 

 afterwards glabrous above and nearly or quite glabrous below ; 

 upper surface dark green, shining, reticulately rugose from all 

 the veins, even in the smallest, being impressed (when dried, how- 

 ever, some of the veins are raised) ; under surface dull paler 

 green, white-dotted as is also the upper surface, the veins in- 

 cluding the smaller ones somewhat thickened and reticulately 

 prominent, more especially when young ; veins numerous, pel- 

 lucid; primary veins forming an acute angle with the midrib, 

 those towards the base of the leaf more approximate ; larger 

 leaves about lx± inch, smaller ^X J inch ; petiole about J of the 

 lamina in length, grey- woolly above ; stipules (rare) minute, 

 roundish, glandular, soon disappearing ; leaves involute in verna- 

 tion. Catkins lateral on peduncles about as long as the catkin, 

 and with three or four leaves with buds in the axils, the leaves 

 similar to the other leaves but smaller, and the upper surface 

 mostly glabrous, narrowly red at and near the apex; catkins 

 ovate, short, compact ; rachis stout, woolly ; scales membranous, 

 brownish, clothed with long straight white hairs on both surfaces, 

 broadly spathulate, obtusely rounded and erose at the apex ; 

 capsules (large for the size of the catkin) ovate subulate, slightly 

 compressed obtuse (acute in the young ovary), green tinged 

 more or less with red-brown, slightly hairy especially towards 

 foe top, but sometimes becoming almost or quite glabrous; 

 Pedicel silky or glabrous, stout, shorter than the long, linear, 

 very thin nectary ; style moderate, bifid at apex ; stigmas about 

 as long as the style, bifid, erect, but twisted and recurved at the 

 apex *.
