As the common name suggests this grass produces fine, slender flower-spikes from small, perennial tussocks which occasionally form large communities. Along the cliff top at Jan Juc it is more readily seen in the native Grassland area. It often grows in association with other Wallaby grasses as well as with other native grasses in well-drained locations. It can tolerate long dry periods.
Leaves are sparsely hairy and usually inrolled.
Flower-spikes form in late spring producing finely awned seeds in early summer. Flowering and seeding can continue on into summer if there is rain.

Indigenous uses as provided by the Wathaurung Aboriginal Corporation: The seeds of Wallaby grasses can be ground and used to make flour for dampers and johnny cakes. Many birds also eat the seed that were hunted such as pidgeons and quail.
