Origin of depicted specimens: USA, northernmost California, Del Norte county, Smith River South Fork (Sheep Pen Creek) between Crescent City and Gasquet, 100 m, serpentine, collected by myself May 7, 1971.

Note the different spur length in 7119. The short spurred specimen is likely to present what E. Hultén named P. macroceras var. microceras. I found flowers with normal and short spurs on the same plant.
