Cocklebur

Xanthium strumarium

Description:

The cocklebur plant is a coarse herbaceous annual about 3 feet high. They have erect, stout stems and spreading branches that are angled and often red-spotted. The leaves are alternate, rough to the touch, and broadly triangular to heart-shaped. Cockleburs produce two kinds of flowers. One kind, in short terminal branches, produces only pollen; the other kind, in clusters in the axils of the leaves, produces seed. The fruit is a small, hard, 2-chambered bur, oval in shape and about 3/4 inch long. It is covered with strong, hooked spines. This plant reproduces only by means of its seed.

Habitat:

LakeBelton shoreline.
