Aphanisma is a monotypic genus which contains the sole species Aphanisma blitoides, a rare annual plant known by the common names San Diego coastalcreeper or simply aphanisma.
 This is a beach-dwelling plant native to the coastline of Baja California and southern California, including the Channel Islands.
