Discussion
Specimens of subsp. decumbens from Alberta, New Brunswick, Saskatchewan, and Arizona represent historical collections that apparently did not persist.
Subspecies decumbens is extremely variable. A slender, nearly apetalous variation with a greater frequency of 4-merous flowers has previously been recognized as var. smithii; the range of variability is continuous and it seems best to consider the material as a single taxon.
