Arid hills in the rain shadow of the Diablo Ranges. Most frequently on adobe or gypseous clay soils, in grasslands, herb-rich openings in scrub, or herb-rich openings in oak woodlands. Appearing only in wet years in many known sites.
Annual herb <9dm tall; entire plant with golden brown glandular trichomes; flowers showy, with 8–16 ray flowers, their ligules <20 mm long; anthers of disk flowers black; very similar in gross habit and appearance to Monolopia major (which differs technically in having a naked receptacle, i.e. without marginal chaffy bracts).
February to May
None locally; Tumey Hills (Fresno County)
Endemic to the South Coast Ranges of California
Extirpated localities are in the northern end of the range in the Mount Diablo region. This species is likely to occur in the the SCoR portions of Stanislaus and Merced counties. Two reported occurrences from the floor of the San Joaquin Valley in Kern County are unverified. Plants are easily damaged by cattle of trampling of clay soils on steep hills.
