Woolly cup grass

Eriochloa villosa

A summer annual weed of agronomic crops. Seedlings are relatively robust with wide leaves that are covered with very short (1 mm or less) hairs. Seedlings are often tinged red at the base. Mature plants have leaves with very short hairs on both surfaces. Leaves have rough margins, are without auricles, and have a small ligule that is a fringe of hairs. Leaf sheaths can root at the nodes. The seedhead is a branched panicle that contains the relatively large tan seed (4 to 5 mm) with a distinctive "cap" at the base.
