from The Century Dictionary and Cyclopedia
- n. A weed, Solanum rostratum, a native of the great plains of the western United States, thence spreading east-ward. The fruit fills closely the extremely prickly calyx.
- n. The bur-grass, Cenchrus tribuloides. (See bur-grass, 1, with cut.) The sand-bur is widely distributed in sandy soils in North America, and is also found in Mexico and South America. It is an annual weed, very noxious on account of its spiny, adhesive fruits. Also one of several other species of Cenchrus, as c. macrocephalus, the large sand-bur. Compare hedgehog-grass.
