Erawan TS, Alillah AN, Johan Iskandar J. 2018. Ethnobotany of ritual plants in Karangwangi Village, Cianjur District, West Java, Indonesia. Asian J Ethnobiol 1: 53-60. According to Sundanese tradition, each Sundanese village community practice some distinctive traditional rituals in which diverse plants grown in different local ecosystems are used. The objectives of this study were to document the traditional rituals performed by the people of Karangwangi Village, Cianjur, West Java, Indonesia and various plants used in these traditional rituals, by employing qualitative and quantitative ethnobotanical approaches. To collect primary data, techniques namely observations and deep interviews were applied. The results of the study showed that 6 kinds of traditional rituals have been practiced by the village people of Karangwangi. These traditional rituals are locally named as srokalan (the traditional ritual of naming the baby), nikahan (the traditional ritual of wedding), nujuh bulanan (the traditional ritual associated with seventh month of pregnancy), nyepitan (the traditional ritual of circumcision), upacara pare (the traditional ritual of planting rice) and upacara nelayan (traditional ritual of fishermen before going to sea). As many as 26 species representing 17 families of plants are used in these rituals. The plants used in traditional rituals were harvested mainly from the homegarden systems and most of these species also commonly used as spices. As the plants used in the traditional rituals have been predominantly cultivated in the homegardens, these plants are indirectly conserved by the village people.
