Nepalese browntop is a delicate, sprawling, annual grass that is ½ to 3 ½ ft. (0.2-1.1 m) in height. The leaves are pale-green, alternate, lance-shaped, 1-3 in. (2.5-7.6 cm) long, asymmetrical with a shiny, off-center midrib. Stems usually droop. Flowering occurs in late-summer, when delicate flower stalks develop in the axils of the leaves or at the apex of the stems. Most commonly an invader of forested floodplains, Nepalese browntop is also found in ditches, forest edges, fields, and trails. It is very shade tolerant and can displace vegetation native to floodplains. Nepalese browntop is native to Asia and was accidentally introduced into North America sometime around 1920. It has previously been used as packing material for porcelain, possibly explaining its accidental introduction. |
