binomial_authority = (Benth.) Gray"Hesperevax caulescens" is a small flowering plant in the daisy family. One common name for the plant is hogwallow starfish, as it is a somewhat flat, star-shaped plant which grows in mud. Another common name is dwarf dwarf-cudweed, as the three members of genus "Hesperevax" are known as dwarf-cudweeds and this species is smaller than the others. It may also be called involucrate evax, since its former Latin name was "Evax involucrata". This annual plant is a member of the
vernal pool plant community inCalifornia , where it is possibly an endemic species, although its range might extend intoBaja California . The hogwallow starfish radiates pale green spoon-shaped leaves in a basal rosette and extends a short erect stem. The flowers are less than two millimeters wide. This species grows along the outskirts of vernal pools in areas which have dried.External links
