New Guinea is the most floristically diverse island in the world, home to nearly 5,000 tree species alone. Trees of New Guinea details each of the 693 plant genera with arborescent members found in New Guinea, covering the entire region including the West Papua and Papua Provinces of Indonesia, Papua New Guinea, and the surrounding islands such as New Britain, New Ireland, and Bougainville. The book follows contemporary classifications and is richly illustrated with line drawings and color photographs throughout. Each group has a family description and key to the New Guinea tree genera, followed by a description of each genus, with notes on taxonomy, distribution, ecology, and diagnostic characters. Trees of New Guinea--winner of the Council on Botanical and Horticultural Libraries Literature's 2022 Award for Excellence in Botany--is an essential companion for anyone studying or working in the region, including botanists, conservation workers, ecologists, and zoologists.
