The first of a 14-volume flora produced by the National Parks Board Singapore. Volume 1 contains the introductory chapters. The Flora of Singapore aims to describe the more than 3,000 native, naturalised and casual species of plants in Singapore. Botanists have been collecting and studying the plant diversity of Singapore for over 200 years, but never before has there been a comprehensive consolidation of all major plants groups only for Singapore. As of now, over 100 experts have committed to contribute to the project, more than half of which are based outside of Singapore. With the rigorous approach taken to ensure taxonomic and nomenclatural accuracy, the Flora of Singapore will be of interest to anybody studying the plant diversity of Singapore.
