“…Morphological markers of Nepenthes had been widely used in genetic diversity studies, including N. gymnamphora and N. mirabilis (Iqbal and Susandarini, 2015), N. ampullaria, N. gracilis, N. rafflesiana and N. mirabilis (Selviana et al, 2018), N. ampullaria, N. tobaica, and N. mirabilis (Mukra et al, 2018, N. gymnamphora (Putra and Fitriani, 2018), N. grancilis Korth., N. maxima, N. refflesiana Jack., and N. mirabilis (Cahyono et al, 2019). The use of morphological markers to evaluate the genetic diversity of Nepenthes in Indonesia was still limited in some populations such as N. gracilis Korth, N. rafflesiana Jack, N. mirabilis, N. khasiana, and N. ampullaria.…”
