Bilimbia [Rheede] Rchb. (Oxalidaceae) is not validly published, whereby Bilimbia De Not. (Lichenes) is not a later homonym and must replace Myxobilimbia Hafellner. In an Appendix, the nomenclatural implications are acted upon: Bilimbia De Not. is re-instated and the new combination Bilimbia lobulata (Sommerf.) Hafellner & Coppins is made.
