A thin, feeble-shaped perennial grass found under coniferous forests in the subalpine and cool temperate zones (illustration). The thin stems and leaves grow sparsely and in a clump, with a thin, short underground stem. The stem is 40-70cm tall, thin and weak, and the base spreads slightly sideways. The leaves, one or two at the base and one at the top, are attached to the nodes of the stem, thin and linear, 10-20cm long, 1-2mm wide, slightly inward-curling, and sometimes sparsely hairy. In June and July, a panicle is produced, 5-8cm long, slightly drooping at the tips, and 5-12 spikelets are produced on thin, drooping branches, and the whole is pale green with a purple tinge.
