Perennial, 62–71 cm tall, leaf sheath 5–11 cm long, pilose ciliate, blade 10–13 mm wide; panicle 11–13 cm long; spike 2.8–3.1 mm long, fusiform-elliptic; lower glume 0.3–0.6 mm long, fan–shaped. The characteristic features that set this species apart from other members of the genus in Hawai‘i are its stiff lanceolate leaves and short clasping lower glume.
