Microseris paludosa
Microseris sylvatica
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.

The range of Microseris sylvatica includes the Central Valley of California and surrounding foothills. It is becoming rare because of grazing and agriculture (D. P. Tibor 2001). An autotriploid form, 2n = 27, has been reported from Placer County (A. S. Tomb et al. 1978); it reproduced clonally by adventitious buds on lateral roots.
