Lasthenia minor
Lasthenia ornduffii
Lasthenia minor is variable; coastal plants tend to have lower stature and broader leaves and tend to flower later in the year. Inland populations were once common in the San Joaquin Valley and are now harder to find as grasslands become cultivated, grazed, or built upon. Epappose plants are common and sometimes comprise entire populations.

Of conservation concern.
Lasthenia ornduffii is known only from six or so populations in grasslands along the immediate coast in Curry County. The plants are usually scapiform.
