Browntop Millet: Brachiaria ramosa
|Weed Description: A summer
annual with relatively wide leaves and open panicles. Browntop millet may grow erect
or prostrate along the ground with tips ascending. This grass is primarily a weed of
agronomic crops, hay fields, and abandoned fields.
Flowers: Seedhead an open panicle, 1 1/2 to 7 inches long, 3/4 to 2 1/2 inches wide. Individual grains are tan in color, ellipsoid, and approximately 2 mm long.
|Stems: Plants go erect or
prostrate along the ground with tips ascending. Stems may reach 3 1/2 feet in
height. Nodes along the stem are minutely to shortly hairy, and sheaths between the
nodal sections are without hairs. Sheath margins may be hairy.
Roots: A fibrous root system.
|Leaves: Leaf blades may reach 7
inches in length and 15 mm in width and are without hairs on both surfaces. However,
minute hairs may occur on the upper leaf surfaces near the leaf bases, but these are
rarely visible to the naked eye. Leaves are without auricles and have a ligule that
is a fringe of hairs approximately 1/2 to 1 1/2 mm long.
Identifying Characteristics: A summer annual grass with relatively large leaves that have a small ligule that is a fringe of hairs and is otherwise essentially hairless throughout. Wild-proso millet (Panicum miliaceum) is very similar to browntop millet, however wild-proso millet has sheaths that are densely covered with conspicuous hairs. Wild-proso millet also appears to be more common in Virginia than browntop millet.
