Introduction Introduction 1 The majestic genus Rhododendron boasts both numerous and varied species, together with a very large number of additional ‘natural’ and ‘man-made’ hybrids. This photographic pocket guide has been developed to aid the recognition and identification of those species that have been fully described and are currently in cultivation. In a publication of this size, a few rarities or species of doubtful provenance are not included; those omitted, together with others not yet in cultivation, are listed as an appendix. Descriptions of many of these can be found in less portable books, which are listed in the bibliography. Interpreting the species descriptions With a few exceptions, designed to assist in comparing two species of very similar appearance, the species are placed in the Subsections of the Edinburgh Review, as listed in The Rhododendron Handbook 1998 (RHS, 1997). With a few exceptions, where they are misleading, the names used in that classification are given first, followed by Davidian’s name if this differs. Close attention to Davidian’s species descriptions will usually lead to the identification of a rhododendron. To help speed up this process, the more significant features are highlighted next to the photographs, with the key points being given double emphasis in bold type. Additional brief comments, where thought helpful, have been given at the end of Davidian’s description. Where a taxon described as a full species by Davidian has been reclassified as a subspecies or variety, or submerged altogether, the description is indented under the species into which it has been incorporated. A full glossary and explanation of terms used can be found on page 668. PETALS (COROLLA) SEPALS (CALYX) Basic rhododendron anatomy STAMEN } ANTHER FILAMENT STIGMA STYLE OVARY } PISTIL
