The Revision of Rhododendron

Publication of the taxonomic revision of genus Rhododendron began in 1980 with Volume 39 No. 1 of the Notes from the Royal Botanic Garden Edinburgh. This brought into use the current classification with which we are now familiar, commencing with the lepidote species of Subgenus Rhododendron and followed by Volume 39.2 in 1982 with the elepidotes of Subgenus Hymenanthes.
