Monrosia pterolopha
Monrosia pterolopha is a species of flowering plant in the family Polygalaceae. It is a subshrub native to Catamarca, La Rioja, and San Juan provinces of northwestern Argentina, where it grows in subalpine areas of the Andes.
The species was first described as Polygala pterolopha by Robert Hippolyte Chodat in 1893. In 1949 Eduardo M. Grondona placed it in the newly-described genus Monrosia.
