LUZIOLA Juss.
Plants monoecious, stoloniferous, annual or perennial (ours). Culms erect or ascending or decumbent or floating and rooting at the nodes, glabrous; internodes hollow; terete. Leaves cauline (tessellate), not distinctly distichous; sheaths terete, margins open; auricles absent; ligules membranous; blades flat, linear, stiff or lax, apex acute to acuminate. Inflorescences reduced to a single spikelet or a panicle (terminal-staminate, axillary-pistillate), primary branches spreading or ascending, open or narrow. Spikelets unisexual. Staminate spikelets solitary, laterally compressed, disarticulation below the spikelet, awnless, pedicellate; florets 1, callus glabrous, rachilla not extended beyond floret, awnless; glumes absent (0); lemmas 7-veined, hyaline, apex acute; paleas 5-veined, awnless, glabrous. Stamens 6; anthers yellow. Pistillate spikelets solitary, terete or laterally compressed, disarticulation below the spikelet, awnless, pedicellate; florets 1, callus glabrous, rachilla not extended beyond floret, awnless; glumes absent (0); lemmas 7-veined, membranous, glabrous, apex acuminate, awnless; paleas 5-veined, awnless, glabrous. Caryopses elliptical to subglobose, yellow, terete. Base chromosome number x=6. A small genus of about 11 species that are adapted to wetland habitats.
