Abstract

Caelospermum is the original spelling of the generic name, as it appeared in the protologue, but in literature and online databases, the variant spelling Coelospermum is often used. However, the confusion about the spelling is caused by a misinterpretation of the etymology. Here, we demonstrate that the original spelling by Blume should be retained.

Keywords: Carl Ludwig Blume; Greek; Latin; Rubiaceae; etymology; nomenclature; orthography.
