Plant Notes:Florida Peanut Grass is a native perennial in the Grass family (Poaceae). It is found in the southern-most counties of Alabama. Florida Peanut Grass grows in moist open areas such as low pine woodlands, around depression ponds, and in roadside ditches. It is a perennial from a long-creeping rhizome. Culms (stems) are erect to decumbent, 1-3 feet in height, green in color, with the leaves more or less evenly distributed along the stems. The leaves are linear, glabrous, and entire. The leaves have a thin white border along their margins. The leaf sheath is glabrous to slightly pubescent. Flowers are produced in spikelets of two florets that are solitary or in open panicles. Two types are produced—subterranean and aerial. The aerial spikelets are sterile or mostly so and the subterranean spikelets are fertile. The subterranean spikelets are ellipsoidal in outline, with one glume. The aerial spikelets are lanceoloid in outline with 1 or 2 unequal glumes. Florida Peanut Grass is listed as a S1 species in Alabama (typically 5 or fewer occurrences, very few remaining individuals, or some factor of its biology making it especially vulnerable in the state) and globally as a G4 species (imperiled globally because of rarity or very vulnerable to extinction throughout its range because of other factors).—A. Diamond.
