WOOD ANATOMY OF <em>GREWIA</em> AND <em>MICROCOS</em> FROM PENINSULAR MALAYSIA AND BORNEO

Abstract

CHUNG, R. C. K., LIM, S. C., LIM, A. L. & SOEPADMO, E. 2005. Wood anatomy of
Grewia and Microcos from Peninsular Malaysia and Borneo. The wood anatomy of
Grewia (one species) and nine species of Microcos from Peninsular Malaysia and Borneo, and their type species (G. occidentalis and M. paniculata) which occur outside the regions were studied. The wood anatomical survey in this study supports the separation of Microcos from Grewia as reported in the literature. Characters to separate these genera are the outline of vessels, the arrangement, shape and aperture size of intervessel pits, type of axial parenchyma pattern, and density of uniseriate rays. The tile cells in G. polygama belong to the Pterospermum-type, while those of Microcos are classified as intermediate to Durio-type.
