Perennials with aromatic shoots (coumarin-scented), rhizomatous or caespitose or rarely stoloniferous, bisexual. Leaves: ligule an unfringed membrane; blade rolled in bud. Inflorescences paniculate, open or somewhat contracted.

Glumes 2, very unequal to ±equal, ±equalling florets, awnless, usually keeled; lower glume 1–5-nerved; upper glume 3–5-nerved. Lower florets: lemma 5-nerved, sometimes shortly awned; palea 2-keeled; stamens 3 or absent. Bisexual floret: lemma awnless or mucronate, rounded on back, 3–7-nerved; palea keeled, 1-nerved; lodicules present; stamens 2. Caryopsis: hilum short; embryo small.
