The correlations of microphotograph structure properties were made via a matured cultivated three-year-old tropical bamboos namely Gigantochloalevis and G. scotechinii. Bamboos were elected and harvested from the plantation plots located at the Forest Research Institute Malaysia in Kepong, Selangor. The studies focused on the vascular bundles and fibres the resided at the internodes and nodes positioned in seven, eight and nine at the outer, middle and inner cross-section of the bamboo culms. Data was collected according to the sizes of the vascular bundle's length, vascular bundles width, fibre length, diameter, lumens diameter, walls thickness and fiber Runkle’s ratio between each of the bamboo species. The two bamboo species manifested similar in characteristics but having different sizes in anatomy and microstructure features. The results in the fibre's morphology studies showed that the textures for each species possess different anatomy characteristics and properties in having different lengths, diameters, cell walls thickness and lumen sizes. The size of the vascular bundle is smaller at the outer position and become more prominent at the central locations.
