The Tree Flora of Sabah and Sarawak is an account of the families of trees that occur in these two botanically rich Malaysian states situated in the island of Borneo. The Flora provides identification keys and illustrations for all families treated and descriptions of all species that grow to a significant size, usually taken as at least 10 cm diameter or 5 m high, although in many cases will be found a complete treatment of all species in a group.
