Although the plant sends out rooting branches, it is a clump grass; the runners are above ground and not 'ropey' and underground, unlike another benign grass that looks virtually identical.

The blades have a few scattered long hairs on the upper surface and often have scattered hairs at the base of the otherwise nonhairy lower surface. The seedheads of spiny burs are 2-8.5 cm wide and 4.1-7.0 mm long to the tip of the spikelets. The spines of only one kind are flattened and spread over the body of the bur. The seedheads appear throughout the year.
HABITAT This weed occurs throughout Florida in dry, sandy, cultivated and disturbed areas; in warmer parts of the United States from Virginia to California; Mexico; Central America; South America; the West Indies; the Philippine Islands; and South Africa.
BIOLOGY The southeastern United States has two similar weedy sandspurs. These are the Coast Sandspur and the Southern Sandspur (C. echinatus). Only one kind of spine on the bur of the Coast Sandspur separates it from the Southern Sandspur.
