Calophylluminophyllum is an indigenous species and distributed mostly at shoreline areas in Indonesia. Genetic conservation of this species inits natural habitats is very important. A study aimed to assess genetic diversity and structure of C. inophyllum at Dompu natural forestwas carried out. Leaf samples were collected from three natural populations at Dompuregency (Kilo, Kempo and Pekat). Genetic analysis was carried out using six simple sequence repeats (SSR) markers. Private alleles were only found at Kilo population. Number of detected alleles (NA), values of alleles diversity (AR) and gene diversity (HE) were also higher at Kilo (NA: 17; AR: 2.219; HE: 0.339) than at Kempo (NA: 10; AR: 1.661; HE: 0.219) and Pekat (NA: 12; AR: 1.941; HE: 0.276). The values of the inbreeding coefficients (FIS) were insignificant among the populations. The medium- scale genetic structure showed that genetic relations. Fine-scale genetic structure analysis showed insignificant genetic structure among trees in distance of 2 m at Kilo and 400 m at Pekat, respectively, suggesting that C. inophyllum was dispersed as far as 2 m to 400 m.
