Abstract: The morphological characteristics of the stems(with or without resin), young roots and leaves of Dracaena cambodiana Pierre ex. Gagnep were observed by traditional paraffin section and photomicrographic technique. Old stems mainly four parts, suberizative layer, cortex, cambium and basic tissue. The resin was mainly distributed in the vessels and fibers of vascular bundles in the basic tissue. Isolateral leaf, and stomata with a clear substomatic chamber were mainly distributed in the lower epidermis, a lot of fiber bundles in the upper and lower epidermis. The structure of younger roots consisted of velamen, cortex and central cylinder. Some parenchyma cells of root, stem and leaf containing calcium oxalate crystal bundle. The structural characteristics of nutritive organs suggested that the plant might adapt to the drought, high temperature and infertile environment. These results can provide the basic anatomical evidence for the development and utilization of D.cambodiana.
