The cymes of Anemone cylindrica may appear 1-tiered because the second tier of involucres is closely nestled among the leaves of the first tier. The cymes then resemble umbels with unusually leafy involucral bracts; they might be misinterpreted as such.
Anemone cylindrica was used medicinally by Native Americans for headaches, sore eyes, and bad burns, as a psychological aid, and as a relief for tuberculosis (D. E. Moerman 1986).

1. Stamens 30–60; abaxial color of sepals same as adaxial color; margins of involucral bracts similar to those of basal leaves. | var. oregana |
1. Stamens 60–75; abaxial color of sepals different from adaxial color; margins of involucral bracts more coarsely serrate than those of basal leaves. | var. felix |
