Abstract

We describe and illustrate Astragalus tijuanensis, morphologically related to Astragalus palmeri, and Astragalus brauntonii var. lativexillum as a new species and a new variety respectively from extreme northwestern Baja California, Mexico. Both new taxa were discovered growing on specialized clay soils in a recently burned chaparral habitat, both taxa are extremely rare and threatened.
