Hesperevax acaulis is a species of flowering plant in the family Asteraceae, commonly known as stemless dwarf cudweed. It is native to California and Oregon, and grows in a variety of mountain, valley, and coastal habitats, including areas recently affected by wildfire. It is a small, woolly annual that forms a small bunch on the ground, sometimes with a stem a few centimeters long. The wool-coated leaves are arranged in pairs or clusters, and the inflorescence is a single flower head or tightly packed cluster of several heads, each just a few millimeters wide. The flower head contains several tiny disc florets.
