bark: branchlets short, stout, very leafy, tomentose-pubescent : leaves 

 broadly obovate: veinlets only gradually divergent from the midrib and 

 directing the lobes somewhat digitately toward the apex of the leaf which

 1-3 inches long, on petioles 2-6 lines long, dark green above, at length be- 

 coming whitish and strongly reticulated beneath : aments densely flowered 

 erect or spreading 1-4 inches long : bracts silky, sepals ovate : stamens about

 flowers sessile, or rarely in spikes : cups covered with small triangular ap- 

 pressed scales, more or less hidden in the dense yellow or fulvous tomen • 

 turn, very variable in shape and size, 4-12 lines wide, hemispherical and 

 rather thin to flat saucer-shaped and very thick with a broad thick rim :
