The final volume of this excellent comprehensive account of the Kinabalu flora. The systematic section, which includes such families as Rosaceae and Rubiaceae, Melastomataceae and Myrsinaceae, is preceded by chapters on the history of botanical exploration on mount Kinabalu, ecological considerations, distribution factors, and contains at the back, a substantial directory of numbered collections. Enhanced by colour photographs, Volume 5 is a fitting finale to the remarkable achievement which this flora represents.
