In the protologue of Rhododendron adenosum the earlier name R. glischrum var. adenosum (based on the same type: J. F. C. Rock 18228) was cited, but without a full bibliographic reference. Rhododendron adenosum was nevertheless validly published as a new combination under Art. 33.2 of the Saint Louis Code because otherwise it would be validly published as the name of a new taxon. The name R. kuluense was published as a nomen novum for R. glischrum var. adenosum, but slightly later in 1978 (18 May) than was R. adenosum (before 16 May); R. kuluense is therefore illegitimate under Art. 52.1 because it was nomenclaturally superfluous when published.
