Like the preceding species, this plant is a nuisance in pastures. It is small, the stems often but one or two inches high, simple or sometimes clustered in patches, the tubercles on its surface less than a half-inch long, slightly grooved, rather loose, arranged in spiral rows. Spines ten to twenty, nearly a half-inch long, gray and bristly, radiating about a central, stouter, hairy spine, or the latter may be lacking. Flowers reddish yellow, nearly an inch long and of about the same width when fully expanded in bright sunlight, the petals acute and bristle-tipped. Fruit red, nearly globular, about the size of a pea. Seed black and finely pitted.
Means of control the same as for Globe Cactus.
