Field Characters

Similar to S. microphylla which may be differentiated by the absence of conspicuous lateral veins on its leaflets (only the midvein is conspicuous), while Schrinkia hystricina has conspicuous lateral veins on its leaflets.

Animal Use

Cattle graze the tender twigs in early spring before the spines harden. Nutritive value is high. This species is generally considered more important as an indicator of high or improving range condition than a forage producer. Deer browse the stems and leaves, and quail ea the seeds.

Natural History

Found mostly in sandy soils of forested or prairie sites in Louisiana and southeast Texas (USDA 1998).

Habitat

Sandy soils and prairies.
