New Rhododendron Species Discovered in Sulawesi, Honoring Local Nature Guardian

A new species of rhododendron, previously undescribed by science, has been discovered in the Tokorondo Mountains of Poso Regency, Central Sulawesi, Indonesia. The plant has been named Rhododendron yombuwurii, in honor of a local figure dedicated to nature conservation in the region. This new species belongs to the subgenus Vireya, a group of tropical rhododendrons widely distributed across Southeast Asia. Sulawesi, an island known for its numerous endemic species shaped by its unique geological history and geographic isolation, has once again demonstrated its rich biodiversity through this discovery. The find occurred in June 2023 when a research team conducting fieldwork near Tentena encountered a rhododendron specimen that did not resemble any previously described species from Sulawesi. The plant was being cultivated around the Saluopa Waterfall, growing as an epiphyte on the substrate of another plant. Local collectors indicated that this substrate originated from a large fallen tree in Petirorano, part of the Tokorondo Mountains. This mountainous area is situated at an altitude of 1,000–1,800 meters above sea level, approximately 19 kilometers west of the Saluopa Waterfall, which is at an elevation of 560 meters. The discovered plant demonstrated its ability to survive even after being transplanted to the lower-altitude waterfall area. Identifying a plant as a new species requires more than just apparent differences in color or form; researchers must find diagnostic characteristics—specific traits that consistently distinguish it from its closest relatives. This discovery underscores the ongoing exploration of biodiversity in Sulawesi and the significance of local community efforts in safeguarding nature. Information Source: Mongabay Indonesia
