Malacothamnus abbottii
 Malacothamnus abbottii is a rare species of flowering plant in the mallow family known by the common name Abbott's bushmallow. It is endemic to Monterey County California where it has recently been observed at only a few locations. It was historically known from a single specimen collection and the plant was presumed extinct until it was rediscovered in 1990 near San Ardo in the Salinas River drainage.
