A new species of Ceratostema (Ericaceae: Vaccinieae) from Ecuador

Abstract

Tribe Vaccinieae Reichenbach with more than 800 species contains most of the neotropical taxa of Ericaceae Jussieu (Pedraza-Peñalosa 2015a: 35). Species of genus Vaccinium Linneaus (1753: 349) known as blueberries or mortiños in Spanish, are members of Vaccinieae well-known for their economic importance (Pedraza-Peñalosa 2015b: 100). The genus Ceratostema Jussieu (1789: 163) was created by Antoine Jussieu and Ceratostema peruvianum Gmelin (1791: 676) was designated as the type species (Luteyn 1986: 485). It was first treated by Smith in 1952, who published a brief description and an artificial key, recognizing 16 species at that time (Smith 1952). Luteyn (1986) reviewed the genus and provided an updated artificial key to 23 species, including three new ones. Subsequently, a new species from Peru was added and thirteen more from Ecuador were included in the genus (Luteyn 1992, 1996, 2005).
