A New Species of Nepenthes (Nepenthaceae) and Its Natural Hybrids From Aceh, Sumatra, Indonesia

Abstract

VICTORIANO, M. 2021. A new species of Nepenthes (Nepenthaceae) and its natural hybrids from Aceh, Sumatra, Indonesia. Reinwardtia 20(1): 17–26. — A new species of Nepenthes (Nepenthaceae) from Aceh Province, Indonesia, Nepenthes longiptera Victoriano is herein described and illustrated. The species is unique among all other Nepenthes in Sumatra by the presence of wings on its upper pitchers. Comprehensive description, photographs, geographical distribution and preliminary IUCN conservation assessment are provided for the new species. Hybrids of this new taxon with other species are also reported in this paper.

Lithocarpus tapanuliensis (Fagaceae), a new stone oak from northern Sumatra and its role as an important resource for critically endangered orangutans

“…The flora of Sumatra has garnered more interest over the last decade with a variety of plant species being described, like the iconic rafflesia ( Susatya et al 2017 ), enigmatic pitcher plants ( Victoriano 2020 ), several begonias ( Hughes et al 2015 ) and a peculiar pipevine ( Mustaqim and Arico 2022 ). To the authors knowledge, the discovery of L. tapanuliensis is the first new Sumatran Lithocarpus to be described in the last decade.…”

The Influence of Rare Plants Exploration in Taman Eden 100 Lumban Julu on Students' Science Process Skills

“…The description of rare plants found in the Taman Eden 100 forest can be seen in Table 2 below. Nepenthes tobaica or tobaica semar sacs have a variety of colors and shapes of the pouches that make Nepenthes a unique beauty (Victoriano, 2021;Mansur et al, 2022;Tarigan et al, 2023). Ecologically, these nectar pockets function as traps for insects, some reptiles, and other small animals (Mansur et al, 2021;Tarigan et al, 2021).…”

Synopsis of Sumatran Nepenthes (Indonesia)

“…Nine new species of Nepenthes have been published from 2002 to 2022. These are N. izumiae (Clarke et al 2003), N. rigidifolia (Akhriadi et al 2004), N. jamban and N. lingulata (Lee et al 2006 ), N. flava (Wistuba et al 2007), N. naga (Akhriadi et al 2009), N. putaiguneung (Metusala et al 2020), N. longiptera (Victoriano 2021) and N. harauensis (Hernawati et al 2022). Therefore, apart from the debate about the taxonomic status of Sumatran Nepenthes, this study will further refer to the thirty-nine species of Sumatran Nepenthes that occur today.…”

“…Thirty-seven species of Nepenthes occur on the island, and more than seventy-five percent are endemic (Clarke 2001;McPherson 2009). In the last two years, the number of Nepenthes in Sumatra has increased to thirty-nine with the publication of two new species, N. putaiguneung (Metusala et al 2020) and N. longiptera (Victoriano 2021). The publication of these two new species makes Sumatra the island in Indonesia with the second largest number of Nepenthes species after Kalimantan.…”
