The leaves are short and linear, 5-10cm long and 2-4mm wide, soft, slightly whitish green and long and pointed at the tip. From summer to autumn, it produces pale grey panicles. The inflorescences are 8-15cm long, thin, slightly drooping at the tip, and bear numerous spikelets somewhat sparsely on the divided branches.
