The aim of this research is to determine the distribution pattern and population structure of Goniothalamusmacrophyllus (Blume) Hook.f. & Thomson in its natural habitat in the lowland forests of Mount Tilu, Kuningan Regency. Data collection was carried out using the census method with route transects, on each route a sample plot measuring 20 x 20 m was made for 5 observation lines based on encounters with the Goniothalamusmacrophyllus (Blume) Hook.f plant. & Thomson. Data were analysed using the Morisita index to determine distribution patterns. The results of the research showed that there were 264 individuals found with the overall population structure classified into sapling and seedling levels. The distribution pattern of this plant is included in the cluster distribution pattern with a Morisita Index value of 0.5 > 0.
