|discussion=<p>Subspecies californica sometimes occurs with other Lasthenia taxa. R. Ornduff (1993) included L. gracilis within his circumscription of subsp. californica. Coastal forms of subsp. californica tend to have shorter, wider, toothed, fleshy leaves and larger heads; they can be distinguished from L. gracilis by their translucent, brown, linear to subulate, aristate pappus scales and more northern distribution. Sympatric epappose plants of subsp. californica and L. gracilis are not easily distinguished morphologically; molecular markers (R. Chan et al. 2001) show them to be distinct taxa.</p>
