Nomenclatural Notes on the Andean Genera Pycnophyllopsis and Pycnophyllum (Caryophyllaceae)

摘要

The nomenclature of the high Andean genera Pycnophyllopsis Skottsb. and Pycnophyllum J. Rémy is examined. Eight species of Pycnophyllopsis are recognized; lectotypes or neotypes are selected when required; a new species, Pycnophyllopsis smithii is proposed and two new combinations are made. The genus Plettkea Mattf. is reduced to a synonym of Pycnophyllopsis. Ten species of Pycnophyllum are accepted, including a new species, Pycnophyllum huascaranum and lectotypes or neotypes are selected when needed.
