Amblyolepis is a monotypic genus of flowering plants in the daisy family, Asteraceae (order Asterales). It was first described as a genus in 1836 and contains a single known species, Amblyolepis setigera, commonly called the Huisache daisy. Native to southern Texas and northeastern Mexico — including the Mexican states of Tamaulipas, Nuevo León, and Coahuila — the Huisache daisy is a small annual or short-lived perennial herbaceous plant bearing bright yellow ray florets surrounding a central disc, characteristic of the broader Asteraceae family. The genus name and its sole species are closely associated with the brushy, semi-arid scrublands of the Chihuahuan Desert borderlands where the Huisache tree (Vachellia farnesiana) is a dominant shrub, giving the common name its regional flavor.
Distribution
