<![CDATA[This study aims to analyze the morphometry of Dillenia in West Sulawesi and its relationship with abiotic factors in the Buttupuang Protected Forest. This species has ecological, economic, and cultural value, but its population in nature is thought to be declining due to overexploitation and low natural regeneration, putting it at risk of local extinction. Understanding morphological variation and response to environmental factors is important as a basis for taxonomic identification, conservation, and sustainable use. The research methods included measuring the morphometry of leaves, fruits, and stems, as well as abiotic factors, using a sample size of 9 with three replicates, then analyzed using PCA with the PAST application. The dendrogram results showed that the Dillenia population was divided into two clusters, namely cluster I (area A, separated as a distinct group) and cluster II (areas B–C with a similarity index of 96.7%). Biplot analysis revealed that the main abiotic factors associated with morphometric diversity were temperature, air humidity, and soil pH, with growth parameters more closely related to humidity. Area A was influenced by temperature, area B by humidity and growth, while area C was more inclined towards edaphic factors (soil pH) and leaf size.]]>
