Microseris elegans
Microseris paludosa
Microseris elegans is widespread in interior central California, becoming coastal in the southwestern part of its range. It was hypothesized to be one of the diploid ancestors of M. campestris (K. L. Chambers 1955); molecular evidence supporting that relationship was presented by D. Roelofs et al. (1997).

Microseris paludosa in the central coastal region (D. P. Tibor 2001). It differs from M. laciniata subsp. leptosepala in its longer, brownish pappus scales and more southern coastal distribution. It is unusual among the perennial taxa of Microseris in its self-compatibility and ready self-fertilization in culture.
