Abstract

A revision of the seven species of Rhododendron sections Sciadorhodion, Viscidula and Rhodora (of subgenus Pentanthera; Ericaceae) is presented. A cladistic analysis of Rhododendron subgenus Pentanthera is provided, and results in the recognition of four sections: Sciadorhodion, Viscidula, Rhodora and Pentanthera. The species are delimited and compared, their distributions are mapped, and descriptions and practical keys are developed.
