An erect, much branched shrub, 1-2 m. high, woody throughout, the branches slender, divari- 

 cate, terete, gray- fur furaceous, becoming smooth and yellowish in age, old stems with a dark 

 gray bark. Leaves numerous, alternate, spatulate to obovate or oblong, sessile or nearly so, 

 3-15 mm. or rarely 25 mm. long, often with smaller leaves in the axils, entire and rather thick, 

 densely gray-furfuraceous; flowers dioecious, the staminate in dense or interrupted, simple or 

 paniculate, naked spikes, the pistillate in small clusters, these being sparsely leafy, paniculate 

 spikes ; fruiting bracts sessile, cuneate-orbicular, 2-3 mm. broad and usually broader than long, 

 free, spongy, united to the middle or rarely free to the base, the margins deeply laciniate-dentate 

 with linear teeth, the sides cristate-appendaged, tuberculate or sometimes smooth.
