Epacris, and that although there were discernible clades in Epacris, none were "readily recognisable on morphological features", hence there was no cause to split it into smaller genera along cladistic lines. The authors point out that in the Ericaceae family more widely, stamen filaments attached to the corolla tube have arisen independently multiple times, that attachment may be weak, and that reversion to the original plesiomorphic state is not uncommon. In their analyses, the Rupicola–Budawangia group was related to E. calvertiana, E. coriacea, E. gunnii, E. microphylla, and E. purpurascens. They proposed moving all five species into Epacris. The epithet ciliata is already occupied by Epacris ciliata (R.Br.) Poir. (1812), so a new name for Rupicola ciliata was given: Epacris pilosa Crowden 2015. For the three other species which had not previously been members of Epacris, new combinations were proposed with co-author Elizabeth Anne Brown as the taxonomic authority. Thus the concepts for Rupicola have been: Rupicola Maiden & Betche 1898: R. sprengelioides Maiden & Betche. Rupicola Summerhayes 1927: R. sprengelioides Maiden & Betche, R. gnidioides Summerh. Rupicola Telford 1992: R. sprengelioides Maiden & Betche, R. apiculata (A.Cunn.) I.Telford, R. ciliata I.Telford, R. decumbens I.Telford. Rupicola Quinn, Crowden, Brown, et al. 2015: grouping of species within Epacris. Names: E. apiculata A.Cunn., E. decumbens (I.Telford) E.A.Brown, E. pilosa Crowden, E. sprengelioides (Maiden & Betche) E.A.Brown. References Further references not sighted: Summerhayes, V. S.
