Ecology & Natural History

Habitat: Species is distributed on waste ground, roadsides, railroads, fields. It is especially common on sand or in sandy light soils of any kind.

ILPIN Notes: Spiny burs can cause injury. The burs..., strongly adhering to shoelaces, socks, trouser cuffs and even flesh, provide the least amusing episode during a field trip in the other African sand country. Other African species are used as fodder and for porridge and drinks. The unique united bristles represent sterile branchlets. This is the only Illinois species. Culmes are branches, geniculate at the base.
