sandbur, (genus Cenchrus), genus of about 20 to 25 species of grasses native to warm sandy areas of North America, North Africa, Asia, Europe, and the South Pacific. The plants can be used for forage when young, but they later form rounded sharp-spined burs that can catch on the coats of or scratch the faces of grazing animals. Several, including buffel grass (Cenchrus ciliaris), are invasive species in areas outside of their native range.

Sandburs are weedy annuals or perennials, typically less than 100 cm (40 inches) tall. The plants are usually shallow-rooted and spread readily. The leaf blades are generally somewhat twisted and feature a fringed ligule (small appendage) at the leaf base. Sandbur flower spikelets are enclosed in sharp burs that readily detach from the plant when ripe.
