Abstract: The purpose of this study was to identify the anatomical structure of four Cinnamomum species (Lauraceae) and as comparison using Cryptocarya species in same family. Cinnamomum is the potential medical plants species. Wood anatomical and their tentative identification key need to be done. Anatomical properties can be beneficial tool for developing the Cinnamomum species. Anatomical description was performed by microscopic evaluation. In this study, Cinnamomum burmannii Blume, Cinnamomum xanthoneureum Blume, Cinnamomum zeylanicum Blume, Cinnamomum coriaceum Camm and Cryptocarya aromatica Kosterms species were identified. The Standard of diagnostic and quantitative anatomy used the IAWA list of microscopic features for hardwood identification. The mostly diagnostic features of Cinnamomum species and family of Lauraceae founded are alternate intervessel pits, parenchyma vasicentric and oil cells present. Type of parenchyma and vessel-ray pitting can be used to determine among Cinnamomum species.
