Description
Poa macrantha is a perennial grass growing in loose clumps with stems up to 60 centimeters in maximum height. The grass grows from a network of very long, stout rhizomes and stolons which may be up to 4 meters in length, anchoring the grass in its shifting sandy substrate. The inflorescence is a dense series of clustered spikelets which are flattened and longer than wide. The plant is dioecious with male and female individuals bearing different types of flowers; the two flower types are similar in appearance.
