Publication: Bot. J. Linn. Soc. 142(1): 21. 2003.
Origin: Native
Herbarium search: CPNWH
Notes: Taxonomy follows FNA & JPM. Similar to Piperia unalascensis but with a longer spur. Reports of Piperia leptopetala from Klickitat Co., Washington (WS) presumably belong here. FNA treats Piperia leptopetala as a California endemic.
