Abstract

There are three species of Aquilaria found in Sarawak which are A. microcarpa Bail., A. malaccensis Lam., and A. beccariana Teigh. They are trees which have the commercial values which can be used as medicinal purposes and essential oil. This study compared the differences among those three species in morphological and anatomical characteristics of the leaves and wood. The leaves were observed by using herbarium samples and fresh samples. The morphological observations were made by using stereo microscope and the anatomical observations done under light microscopy and Scanning Electron Microscopy (SEM). Aquilaria beccariana had the largest leaves with size of 14.0 – 17.0 cm x 6.0 – 7. 5 cm. The three species where different in the morphology of leaves epidermal cell where A. microcarpa had polygonal isodiametric arrangements of cells, A. malaccensis had the tetragonal rectangular arrangements of cells and A. beccariana had the random isodiametric arrangements of cells. In anatomical characteristics observed, A. microcarpa had the largest stomata with 20.3 µm x 17.2 µm of size. The diameter of the vessels identified A. microcarpa had the largest diameter with 80 µm – 117 µm. Thus, the three species can be differentiated through the observations of the leaves morphological and anatomical characteristics.
