Description

Elytrophorus spicatus is a tufted, annual or perennial plant with bristly culms. The leaves are loosely sheathed, and the blades are rolled in bud. The inflorescence spike (length of up to 26 cm by 5–9 mm wide) consists of globular clusters of spikelets, which are 4 mm long, with bisexual florets. The glumes are shortly awned, about 2 to 3 mm long, and have translucent margins translucent which are sparingly fringed with hairs. The awn and keel are rough. The plant flowers in response to flooding or rain.[5]
