Ecology & Life History

Basic Description: A perennial grass with stout creeping stems (rhizomes) growing at or below the soil surface, inconspicuous flowers, and leaves arranged evenly on the stem. Leaves have white margins when dry.
Technical Description: Perennial; culms usually decumbent at base, rooting at nodes, 30 to 100 cm tall; leaves evenly distributed; blades firm, broadest somewhat above base, up to 1 dm long and 5-10 mm wide, glabrous on both surfaces, margins cartilaginous, margins and ligules ciliate, sheaths glabrous. Aerial spikelets 6-7.5 mm long, pedicels smoothish. Second glume and sterile lemma many-nerved, glabrous, acute, 6-7.5 mm long; indurate lemma and palea acute, 6-7 mm long. Few-flowered, fertile spikelets inconspicuous.
Diagnostic Characteristics: Leaf blades glabrous.
Duration: PERENNIAL
Reproduction Comments: Both vegetative and sexual reproduction. Vegetative reproduction occurs because the culms are decumbent and root at the nodes. Sexual reproduction is a mixture of selfing and outcrossing. The aerial spikelets are chasmogamous (with open flowers) and are wind-pollinated, while the subterranean spikelets cleistogamous (with closed flowers) and are self-pollinated.
Terrestrial Habitat(s): Grassland/herbaceous
Habitat Comments: This species is found in low pinelands (Hitchcock 1950), moist to wet pine savannas and flatwoods, exposed shores and bottoms of ponds and lakes (Godfrey and Wooten 1979) and margins of cypress-gum ponds.
