It is known for its prominent V-shaped inflorescence consisting of two spike-like racemes containing multiple tiny spikelets, each about 2.8–3.5 millimetres (0.11–0.14 in) long.

This grass is low-growing and creeping with stolons and stout, scaly rhizomes.

The stolons are pressed firmly to the ground and root freely from the internodes, forming a dense sod.

[1] The terminal dual racemes are each attached to the top of a slender stem or with one slightly below the other.

It is also valued as an erosion-controlling soil stabilizer, as well as for its productivity, ease of establishment, and persistence.
