Discussion

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.
