[Botany • 2016] Clinanthus milagroanthus • A New Species of Clinanthus from northern Peru (Asparagales, Amaryllidaceae, Amarylloideae, Clinantheae)


Clinanthus milagroanthus 
S. Leiva & Meerow


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 C. mirabilis (Ravenna) Meerow, with further affinities to C. viridiflorus (R. & P.) Meerow. It can be distinguished from C. 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 C. mirabilis). A conspicuous bulge just proximal to the midpoint of the tube is a unique character of the new species.

Keywords: Geophyte, Andes, Clinantheae, new species, taxonomy

Resumen: Clinanthus milagroanthus S. Leiva & Meerow, sp. nov. se describe desde el Departamento de La Libertad, Perú. La nueva especie es más estrechamente relacionada con C. mirabilis (Ravenna) Meerow, con adicionales afinidades con C. viridiflorus (R. & P.) Meerow. Se puede distinguir de C. mirabilis por sus hojas más anchas, el limbo mucho más amplio de colores brillantes, y el color de tubo perigonio mucho más claro (color amarillento vs. verde verde oscuro en C. mirabilis). Una protuberancia visible casi proximal al punto medio del tubo es un carácter único de la nueva especie.
