Culm-nodes constricted (1/13), or flush with internodes (1/13), or swollen (11/13). Lateral branches lacking (6), or sparse (3), or ample (7), or suffrutescent (33), or dendroid (10). Branch complement one (52/52), or three (3/52); solitary (50/52), or in a horizontal line (2/52); as thick as stem (42/42). Culm-sheaths persistent (38/39), or deciduous (1/39); without auricles (28/32), or auriculate (4/32). Culm-sheath blade linear (2/15), or lanceolate (11/15), or ovate (1/15), or triangular (3/15). Leaf-sheath auricles absent (55), or falcate (3). Ligule an eciliate membrane (55), or a ciliolate membrane (3). Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades linear (1), or lanceolate (34), or elliptic (6), or oblong (41), or ovate (2); herbaceous (52), or chartaceous (3), or coriaceous (3). Leaf-blade venation without cross veins (47), or with distinct cross veins (11).
    Inflorescences
    Inflorescence a panicle (33/36), or composed of racemes (2/36), or comprising only a few spikelets (1/36); exserted (35/36), or embraced at base by subtending leaf (1/36). Panicle open (33/33). Racemes single (2/2). Spikelets solitary (36/36). Fertile spikelets pedicelled (36/36).
