Description

• Cenchrus echinatus, commonly known as southern sandbur or spiny sandbur, is an annual grass in the grass family (Poaceae). It has spreading or upright stems, narrow leaves, and seed heads bearing clusters of hard, rounded burs covered in stiff, sharp spines. These burs readily cling to clothing, animal fur, and skin, helping the seeds disperse. The spiny burs can be painful when stepped on and make the plant a troublesome weed in some areas.

Range

• Cenchrus echinatus is native to tropical and subtropical America, including Mexico, Central America, the Caribbean, and parts of South America. It has spread to other warm regions worldwide. It is native to Zihuatanejo, Guerrero, and the surrounding area.

Habitat

• Southern sandbur grows in sunny, open environments, including sandy beaches, coastal areas, grasslands, roadsides, agricultural fields, and disturbed ground. It thrives in warm conditions and tolerates dry, sandy soils. Its burs can be particularly common in areas with sparse vegetation and exposed soil.
