Leguminosae Payung; Thailand Rosewood Distribution This species is found in Cambodia, Thailand, Laos and Viet Nam. Habitat In Viet Nam the tree grows sparsely in open and semi-deciduous forests, occasionally in pure stands. Mainly concentrated at altitudes of 400-500 m preferring deep sandy clay soil and calcareous soil (Vu Van Dung, 1996). Population status and trends In Viet Nam, D. cochinchinensis is found south of Quang Nam-Da Nang, mainly in Gia Lai and Kon Tum; it in other provinces it is sparsely distributed in a few localities (Chính et al, 1996). Regeneration This species is shade tolerant as a sapling and becomes light demanding. D. cochinchinensis has quite a slow growth rate. It regenerates well by coppicing (Chính et al, 1996). Role of species in the ecosystem No information. Threats Deforestation and exploitation are threats to this species. Utilisation D. cochinchinensis is considered a `first class prime timber', as it is hard, durable, easy to work and resistant to insects. The distinctive heartwood makes beautiful patterns when cut and the wood is used to make furniture, carvings, musical instruments and sewing machines (Chính et al, 1996). In Viet Nam the species is classified as a first class prime timber. It is used for furniture, wood turnery, fine-art articles, musical instruments and sewing machines (Vu Van Dung, 1996).

Conservation measures A current IPGRI project is looking at the distribution of genetic resources of this species in its range countries. It is found in some nature reserves (Asia Regional Workshop, 1997). Forest management and silviculture References Asia Regional Workshop, 1997.
