TL;DR: A new classification of Ericaceae is presented based on phylogenetic analyses of nuclear and chloroplast DNA sequence data, morphology, anatomy, and embryology, and three new taxa are described: Oligarrheneae, Richeeae, and Cosmelieae (all within Styphelioideae).
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).

TL;DR: In addition to enhancement of host nutrition in circumstances of low nutrient availability, it is shown that ericoid mycorrhizal infection leads to restriction of uptake of metallic elements when these are pr...
Abstract: The types of mycorrhizal structure seen in the Ericaceae and in the closely related families Pyrolaceae and Monotropaceae are reviewed briefly. Ericoid, arbutoid, and monotropoid mycorrhizas are ch...

TL;DR: Results of these analyses indicate strong support for the recognition of a monophyletic Ericaceae that includes Empetraceae, Epacridaceae, Pyrolaceae, and Monotropaceae.

TL;DR: It is concluded that the Ericaceae are a paraphyletic assemblage as presently circumscribed, and that Emetraceae andEpacridaceae are better treated as members of theEricaceae.
Abstract: A cladistic analysis of theEricales based on morphological, anatomical, embryological, and phytochemical data has been undertaken. Resulting from the analysis, 56 equally parsimonious cladograms were obtained. The tribeEnkiantheae was found to be the sister-group of the rest of theEricaceae, in which theEmpetraceae, theEpacridaceae, Pyrolaceae, andMonotropaceae are forming derived ingroups. It is thus concluded that theEricaceae are a paraphyletic assemblage as presently circumscribed, and thatEmpetraceae andEpacridaceae are better treated as members of theEricaceae.

TL;DR: Cladistic analyses of selected taxa of Ericaceae suggest that the family, as traditionally circumscribed, is paraphyletic, and preliminary analyses suggest that Actinidia (Actinidiaceae) likely is cladistically basal within Ericales.
Abstract: Cladistic analyses of selected taxa of Ericaceae (and potential relatives) suggest that the family, as traditionally circumscribed, is paraphyletic. The traditionally recognized groups, Monotropaceae, Pyrolaceae, Epacridaceae, and Empetraceae, are nested within the cladistic structure of Ericaceae, and it seems reasonable to expand the circumscription of the latter. Preliminary analyses suggest thatActinidia (Actinidiaceae) likely is cladistically basal within Ericales, withCyrilla (Cyrillaceae) andClethra (Clethraceae) positioned, respectively, as second and first outgroups to Ericaceae. Generic relationships within Ericaceae are highly unresolved due to extensive homoplasy, butEnkianthus appears to be the sister group of the remaining ericad genera. The current division of the family into five subfamilies, i.e., Rhododendroideae, Ericoideae, Vaccinioideae, Pyroloideae, and Monotropoideae, very likely is not in accordance with phylogenetic relationships.
