About

Vauquelinia, commonly known as the rosewoods, is a genus of the rose family, Rosaceae. It consists of four species of shrubs found in the southwestern United States and northern and central Mexico. The genus was named for French chemist Louis Nicolas Vauquelin (1763-1829). The nectar provided by these plants is commonly fed on by wasps such as Polistes instabilis.
