Rhododendrons are some of Sabah’s most attractive plants and are a significant part of the rich heritage of natural history of which the country can boast. This book describes the 42 species known from Sabah, 16 of which are Sabah endemics, some known only from single localities. There are two artificial keys enabling identification of the species. The first is a simplified key to just those species known from the main Kinabalu massif which is designed for the many tourists visiting the mountain to enable them to easily name the rhododendrons that they see. The second includes all the known species from Sabah and is more technical.
