Abstract
Rhizomatous, stoloniferous, or caespitose perennials, herbaceous or with a woody caudex. Ligule membranous, a fringed membrane, or a fringe of hairs. Inflorescences branched or unbranched, the spikelets pedicellate. Spikelets with glumes 0 or 2, with the two proximal flowers sterile and often reduced, only the distal flower fertile. Flowers bisexual or unisexual. Lemma with or without an awn. Lodicules 2. Caryopsis with hard endosperm, with a long-linear hilum, the embryo with an epiblast, with a scutellar cleft, without a mesocotyl internode, with the embryonic leaf margins overlapping. Fusoid cells absent or present, mesophyll cells with or without invaginated cell walls, midrib simple or complex. Silica bodies in leaves transverse to the proximo-distal axis. Photosynthetic pathway C3. Worldwide distribution.
