ABSTRACT: Mimulus shevockii is a minute annual herb endemic to Kern 
County, California. Several disturbance factors threaten it, including housing 
development, cattle grazing, and off road vehicle activity. Additionally, at least 
one population may have been extirpated when Lake Isabella was filled in 1953. 
This review reports two new occurrences and reevaluates conservation strategies 
recommended in an earlier Conservation Plan (Fraga 2007). 
KEYWORDS: Kem County, Mimulus, Mimulus shevockii , Mojave Desert, 
Phrymaceae, rare plants, southern Sierra Nevada.
