A visual based microscopic identification key for 37 Central African wood species.

The traditional work on wood identification is time-consuming and requires extensive expertise in specimen preparation, microscopy, and with wood anatomical terminology. Identification of wood specimens is typically made using dichotomous keys with text-based wood anatomical characters. Use of these types of keys often results in high error rates. To help overcome these problems we substituted micrographs for text-based characters and used direct comparison of images of unknown wood with reference images from microscope slides. A database of more than 2,000 microstructure images of the wood of 37 commercially important Central African species was created. We attempted to visually capture the important diagnostic features for the 37 species with light microscopy and SEM. Between two to five specimens of each species were investigated, with the goal of documenting as much intra-specific variation as possible. We discuss the development of image-based identification key and interactive teaching for Central African wood species.
