The anatomy and the ultra structure of the stem of coconut palm (Cocos nucifera) were studied using scanning electron microscope (SEM). Field samples each 5-cm thickness disc (n=3) were obtained from the trunk at 1.5,4.5 and 7.5 metre from a 40-50 year-old tree. The samples were examined based on cuts from the peripheral, intermediate and core region of each disc. Examination on the vascular bundles showed their concentration increased towards the stem periphery. Each vascular bundle consists of metaxylem, phloem, axial parenchyma and fibers. Fibers, the support structure of the trunk; constitute over half of the vascular bundle volume. The non-vascular bundles containing fibers can only be seen around the core of the top trunk. Preliminary observation showed that starch granules present in parenchyma cells can easily be seen at the intermediate zone as compared to core and peripheral zone.
