The Mount Sibuatan area is located in Mark District, Karo Regency, North Sumatra. Selaginella which is located in the Mount Sibuatan area is at an altitude of 1550 mdpl-2236 mdpl which has high enough humidity which is a suitable habitat for Selaginella to grow. The purpose of this study was to identify the type of Selaginella found in the Mount Sibuatan area, Brand District, Karo Regency, North Sumatra. The research method used is descriptive with sampling using target sampling with exploratory techniques. The results of the study found 4 species consisting of; Selaginella intermedia (terrestrial, erect, creeping), Selaginella subalpina (terrestrial, erect), Selaginella opaca (terrestrial, epilytic, creeping) and Selaginella s.p (terrestrial, epilytic, creeping). The highest species abundance of Selaginella found were Selaginella Intermedia, this species found at an altitude of 1550 m above sea level, with environment of pH level 5.4 and temperature of 18°C.
