Phylogenetic classification of Ericaceae: Molecular and morphological evidence

The Botanical Review Aims and scope Submit manuscript

Abstract

A new classification of Ericaceae is presented based on phylogenetic analyses of nuclear and chloroplast DNA sequence data, morphology, anatomy, and embryology. Eight subfamilies and 20 tribes are recognized. In this classification Epacridaceae are included as Styphelioideae and Empetraceae as tribe Empetreae within the Ericoideae. The herbaceous taxa previously recognized as Pyrolaceae and Monotropaceae by some authors are also included within Ericaceae, in the subfamily Monotropoideae. A key, morphological descriptions, and representative images are provided for all named groups. Two new combinations inKalmia (K. buxifolia andK. procumbens) are made, and three new taxa are described: Oligarrheneae, Richeeae, and Cosmelieae (all within Styphelioideae).

Resumen

Se presenta una clasificación nueva de las Ericaceae basada en análisis filogenéticos, empleando secuencias de ADN nuclear y de cloroplasto, morfología, anatomía y embriología. Se reconocen ocho subfamilias y 20 tribus. En esta clasificación las Epacridaceae son incluídas como Styphelioideae y las Empetraceae como la tribu Empetreae dentro de Ericoideae. Los grupos herbáceos previamente reconocidos como Pyrolaceae y Monotropaceae por algunos autores también se incluyen dentro de las Ericaceae, en la subfamilia Monotropoideae. Se dan una clave, descripciones morfológicas e imágenes representativas de todos los grupos nombrados. Se hacen dos combinaciones nuevas enKalmia (K. buxifolia yK. procumbens), y se describen tres nuevos taxones: Oligarrheneae, Richeeae y Cosmelieae (todos dentro de Styphelioideae).
