Comments

provided by eFloras
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).
