Endangered Brazilian tree species are traded on national and international scales. Efficient control of wood supply chains is fundamental to both species and environmental conservation. Wood anatomy offers an effective method for timber screening and diagnosis, although diagnostic tools and reliable reference materials are required to verify the precise timber species commercialized. We present here anatomical information that can be used for the identification of the wood of endangered Brazilian tree species, including coded wood anatomy descriptions following standardized lists of macroscopic and microscopic features, stereomicroscope and bright field microscope micrographs, and reference data (wood collections with reference samples and anatomical descriptions). Description datasets and interactive identification keys (macroscopic and microscopic) were made available on the Xper3 web platform (http://gbg.sites.uff.br/lamad/) and can aid trained front-line staff or professional wood anatomists in trade control and forensic timber identifications of endangered Brazilian species.
