Erica L. (Ericaceae): homonyms amongst published names for African species and proposed replacement names

In support of ongoing taxonomic work on the large and complex flowering plant genus (Ericaceae), we document nineteen pairs of homonyms representing currently used illegitimate names. We provide replacements for thirteen names and new typifications for five. We relegate five names to synonymy: Guthrie & Bolus under Bartl.; Klotzsch ex Benth. under H. A. Baker; T.M. Salter under Salisb.; Andrews under Link; and Salisb. under Bartl. Finally, we suggest conservation of Andrews. The new names are: E.C. Nelson & E.G.H. Oliv. replacing E.G.H. Oliv.; E.C. Nelson & Pirie replacing E.G.H. Oliv.; E.C. Nelson & E.G.H. Oliv. replacing Nois. ex Benth.; E.C. Nelson & E.G.H. Oliv. replacing E.G.H. Oliv.; E.C. Nelson & E.G.H. Oliv. replacing Benth.; E.C. Nelson & E.G.H. Oliv. replacing Benth.; E.C. Nelson & E.G.H. Oliv. replacing L.Bolus; E.C. Nelson & Pirie replacing Salisb.; E.C. Nelson & E.G.H. Oliv. replacing Klotzsch ex Benth.; E.C. Nelson & E.G.H. Oliv. replacing Klotzsch ex Benth.; E.C. Nelson & E.G.H. Oliv. replacing Klotzsch ex Benth.; E.C. Nelson & E.G.H. Oliv. replacing Guthrie & Bolus; E.C. Nelson & Pirie replacing Klotzsch.
