Abstract
Clinanthus milagroanthus S. Leiva & Meerow, sp. nov. is described from the Department of La Libertad in Peru. The new species is most closely related to Clinanthus mirabilis (Ravenna) Meerow, with further affinities to Clinanthus viridiflorus (R. & P.) Meerow. It can be distinguished from Clinanthus mirabilis by its wider leaves, the much more brightly colored and wide spreading limb, and the much lighter colored perigone tube (yellowish green vs. dark green in Clinanthus mirabilis). A conspicuous bulge just proximal to the midpoint of the tube is a unique character of the new species.
