Discussion
Piperia cooperi and P. michaelii have very similar flowers, and their blackish brown seeds are unique in the genus. A few specimens from the Santa Monica Mountains, California, described as P. lancifolia Rydberg, have flowers with spurs of intermediate length (6–9 mm).
Selected References
None.
