The plant is monoecious, producing the staminate (male) flowers in a large feathery panicle at the summit, and the (female) dense spikes of flowers, or " cobs," in the axils of the leaves below, the long pink styles hanging out like a silken tassel.
The stamens are placed round the base of the ovary, which is rounded or oblong, much smaller than the glumes, covered with down, and surmounted by two short styles, extending into feathery brush-like stigmas.
The stout horizontally spreading branches give a cedar-like appearance; the foliage is light and feathery; the leaves and the slender shoots which bear them fall in the autumn.
The small flowers or spikelets are borne in pairs on the ultimate branches of a much branched feathery plume-like terminal grey inflorescence, 2 ft.
Oaks and wild prunus, wild vines and sumachs, various kinds of maple, the dOdan (Enkianthus Japonicus Hook.)a wonderful bush which in autumn develops a hue of ruddy redbirches and other trees, all add multitudinous colors to the brilliancy of a spectacle which is further enriched by masses of feathery bamboo.
