The S. melaleuca plant samples were collected from the Hutan Kemasyarakatan (HKM) Pusuk Lestari Area in Batu Layar, West Lombok Regency, West Nusa Tenggara. The samples included the root organs, stems, leaves and seeds. The samples were preserved in 70% alcohol and sliced using the hand-free section method.
