Viola douglasii

Phenology Flowering Feb–Jul.
Habitat Vernally moist grassy slopes and flats, often serpentine soil (except Oregon)
Elevation 20–2300 m [100–7500 ft]

Viola douglasii is tetraploid (n = 12) south of, and octoploid (n = 24) north of, San Francisco Bay, California. It forms sterile hybrids with V. quercetorum (J. Clausen 1964). V. B. Baird (1936) described V. douglasii × purpurea, which Clausen later said was actually V. quercetorum, not described at the time of Baird’s publication.
