Sulawesi Island is a key area of the Wallacea region, known for its high level of plant endemism, including the genus Pogostemon. A comprehensive taxonomic study is essential to document the biodiversity and provide accurate identification for tropical resource management. This study aims to examine the taxonomic characters of Pogostemon spp. collected from Sulawesi and deposited at Herbarium Bogoriense (BO). Using a descriptive method based on morphological characteristics of 13 collection numbers, the study analyzed vegetative and reproductive structures. The results identified two distinct species: Pogostemon cablin (Blanco) Benth. and Pogostemon auricularius Hassk. These species are clearly distinguished by the shape of the leaf blade, calyx structure, and the type of indumentum present on the stem, leaf, and flower surfaces. This taxonomic study contributes to the baseline data of Lamiaceae in Sulawesi, supporting further research in plant ecology and conservation of tropical flora
