A new species of Viola subgenus Neoandinium (Violaceae) from the southern Andes of Argentina

Abstract

A new rosulate species of Viola from the high Andes of Neuquén in Argentina, V. marcelaferreyrae, is here described, illustrated, and categorized according to its conservation status. Additionally, we compare the new species with its morphologically and geographically allied species, V. anitae and V. escondidaensis, and discuss its preliminary placement in sect. Rhizomandinium due to the presence of stolon-like perennating axes. A key to the species of the section together with images to differentiate them and a distribution map are also provided. The new species joins the ever-growing list of known taxa for subgenus Neoandinium.
