Abstract

The wood anatomical characteristics of Dalbergia nigra and Dalbergia spruceana are too similar to permit reliable species separation, which is sometimes important because D. nigra is a Convention on International Trade in Endangered Species-protected species whereas D. spruceana is not. However, the density, water fluorescence, and ethanol fluorescence of heartwood specimens are different between the species and these chracteristics permit the separation of the species. Dalbergia spruceana is denser (≥1.0 g/cm3) than D. nigra (
