Anatomical Identification of Plant Material

An on-demand identification service for wood samples and other fragmentary plant material that requires microscopic examination. This work is supported by our extensive and expanding reference microscope slide collection and staff expertise.

We identify fragmentary plant material for a wide range of customers. Using the microscope slide collection for reference, we identify samples of wood, foreign plant matter in food, fragments of medicinal and poisonous plants, archaeological plant remains, crude drugs and forensic samples for a small fee. The income is used to help fund research such as the CITES timber project. In February 2006 we launched an annual one-week course at Kew on wood identification.

Peter Gasson is collaborating on an interactive wood identification database (Inside Wood) with colleagues at North Carolina State University. This database provides anatomical descriptions and photomicrographs of hardwoods worldwide, and has already become an essential resource for wood identification and systematic and phylogenetic studies of wood characters since its launch in 2004.
