Research on the diversity of rattan morphology has been conducted in three forest conservation areas in South Sumatra, i.e. Bentayan Wildlife Reserve, Bukit Cogong, and Gunung Raya Wildlife Reserve. This study aims to analyze the diversity of rattan morphology in three protected areas in South Sumatra. This research uses purposive sampling method by exploring the forest area. The results showed that in the Bentayan Wildlife Reserve area were found 3 species of 3 families while in Bukit Cogong Protected Forest was found 9 species of 3 families and in the Gunung Raya Wildlife Reserve area were found 5 species of 3 families. The morphology of rattans species in the three regions has different shapes and colors of thorns on the stem, the top and the bottom surfaces of the leaves, the climbing organ and the growth nature. The same rattan species were being found in the same of two or three locations, having morphological differences in diameter and length of the stem.
