Plants of Anemone piperi from southeastern Washington and northeastern Oregon
(i.e., the westernmost limits of the species) are sometimes intermediate between
A . piperi and A . oregana . Although they possess vertical rhizomes characteristic of
A . piperi , they have the bluish or pinkish sepals of A . oregana . These plants are
best referred to A . piperi , pending detailed biosystematic analysis.
