Eriogonum clavatum is the tall, slender member of the E. inflatum complex found on the Inner Coast, Peninsular, and Transverse ranges of southern California. It is rather common from Monterey and San Benito counties southward to Ventura, northwestern Los Angeles, and extreme southwestern Kern counties, and then disjunct in the Peninsular Ranges of Riverside and San Diego counties, where it just enters north-central Baja California, Mexico. It extends eastward onto desert ranges, where it rarely exceeds 6 dm in height, from southern Mono County and Inyo County south through western San Bernardino County to northwestern Riverside County. From Inyo County, the species occurs across southern Nye and northern Clark counties into western Lincoln County, Nevada.
