Paneroa
Paneroa is a genus of flowering plants in the family Asteraceae. It includes a single species, Paneroa stachyofolia, which is endemic to the state of Oaxaca in southern Mexico.
The species was first described as Ageratum stachyofolium by Benjamin [Lincoln Robinson] in 1901. In 2008 Edward E. Schilling placed it in the new monotypic genus Paneroa as Paneroa stachyofolia.
