Microstegium vimineum Nepalese browntop MIVI Japanese stiltgrass Form: Sprawling annual grass, ½-3 ft (0.2-1 m) tall. Leaves: Alternate; narrowly lanceolate 2-4 in. (5-10 cm) long; blades flat and sparsely hairy on both surfaces, as well as along the margins, or sometimes glabrous. Flowers/fruit: Inflorescence a digitate cluster of 2-4 narrow spike-like branches; pubescent; awns usually present on at least some lemmas. Spikelets paired (one sessile, one pedicellate); lower glume keeled, upper flat. Habitat: Flood plains, streamsides, forest edge, roadsides, swamps, wet fields, and trailsides. Other distinguishing features/notes: Although annual, the sprawling stems easily root from the nodes, forming dense colonies. Sometimes confused with Leersia, browntop can be distinguished vegetatively by glabrous nodes and hairs on the leaf sheaths near the collar. Notes
