<![CDATA[Pitcher plants (Nepenthes spp.) are unique and interesting flora that have been widely cultivated as ornamental plants. This species is attractive due to its pitcher shape and diverse colors. Sumatera Island is the second largest center of Nepenthes diversity in the world after Kalimantan Island. Each pitcher plant hybrid has diverse quantitative and qualitative characteristics. This study aimed to describe 18 quantitative and 33 qualitative characteristics of pitcher plants based on morphological markers. This study was conducted in North Sumatra Province in the HPH PT. Teluk Nauli area of Mandailing Natal Regency, Tarutung, North Tapanuli Regency, and Lake Siais, South Tapanuli Regency. The materials used in this study were pitcher plant hybrids, namely Nepenthes mirabilis x N. sumatrana, N. eustachya x N. sumatrana, and N. eustachya x N. mirabilis, with each species consisting of three individuals obtained from the exploration of the sampling locations. The results indicated that N. mirabilis x N. sumatrana exhibited superior traits, including larger pitcher size, wider peristome, and greater color variation highlighting its high ornamental and adaptive potential. N. eustachya x N. sumatrana showed relatively stable intermediate characteristics, while N. eustachya x N. mirabilis displayed unique pitcher morphology and moderate vigor. These findings emphasize the value of hybrids for breeding and the importance of conserving genetic for sustainable Nepenthes utilization.]]>
