Grass - Leersia hexandra
THIS PAGE IS UNDER CONSTRUCTION.
Leersia hexandra is a perennial species that often grows in
dense mats and produces rhizomes and leafy stolons. It grows up to about
1 m tall but is often decumbent and roots from the lower nodes. Short,
dense hairs encircle the nodes of the stem. Leaves are 15 to 18 cm long
and 3 to 6 mm wide. Leaf margins are finely but sharply toothed. The ligule
is membraneous and forms a scale-like collar. The inflorescence is a narrow
panicle with mostly ascending branches. Spikelets are flattened, 4 to
5 mm long, about 1 mm wide, and often purplish brown.
Cutgrass grows along the margins of marshes, streams, ponds, lakes, swamps,
ditches, and canals. Leersia hexandra sometimes forms floating islands
and can grow in water up to 1.8 m deep (Godfrey and Wooten 1979). It spreads
vegetatively by rhizomes and stolons and can also reproduce from seed.
Dense mats along shorelines and in shallow water areas can restrict access
and hinder recreational activities. The plant also can be a weed in ricefields
and slow flow in irrigation canals. Hoyer et al. (1996) note
that floating islands of L. hexandra provide cover for small
fish and serve as resting and feeding sites for wading birds.
