Wild Andaliman (Zanthoxylum acanthopodium DC.) Varieties as an Aromatic Plants from North Sumatera

: Andaliman ( Zanthoxylum acanthopodium DC.) is one of endemic plant in North Sumatera which produce essential oil. This study aims to explore the wild Andaliman varieties and their characteristics based on specimens and any information sourced from local community knowledge in North Sumatera. This research was conducted through a vegetation survey with local communities in three districts based on three altitude levels: North Tapanuli (1500-1600 masl), Samosir Island (1600-1700 masl) and Humbang Hasundutan (1700-1800 masl) using 20 x 20 m plot with three replicates at each altitude level, totaling nine plots. Observation was carried out through morphological characteristics: seeds, leaves, and prickles based on specimens from the fieldwork and observing fruits, leaves, stems and prickles based on local community knowledge by in-depth interview. The results showed that there were nine varieties Andaliman in North Sumatera: Siholpu, Siganjangpat, Sihalus, Sihorbo, Simanuk, Sirangkak and there were three unnamed varieties. Each variety grows in a different altitude and has morphological characteristics. Further research will be carried out, related to the essential oil content of each Andaliman variety and its ecological conditions.
