Discussion
The type specimen of Ranunculus macauleyi var. brandegeei L. D. Benson, from the Sangre de Cristo Mountains, Colorado, differs from typical R. macauleyi in its tall stem, broad, crenate-laciniate leaves, and sepals with pale or transparent hairs. These characteristics are suggestive of R. inamoenus, and the plant may be of hybrid ancestry.
