“…Tentaculatae and Insignes are resolved as successively sister to the rest of Clade 2 with maximal support. Both the Tentaculatae and Insignes clades were described as sections based on morphology (Cheek et al, 2018;Cheek and Jebb, 2016a;Danser, 1928). It is notable that these sections both range across Wallace's line.…”

“…More recently, there have been two main conflicting approaches to adapting this classification in the light of molecular studies and taxonomic work. Cheek and Jebb (2015;2016a, 2016b, 2015 have published an additional five sections (Alatae, Micramphorae, Pyrophytae, Tentaculatae and Villosae), plus subsection Poculae-ovis, and the informal Danseri group, while rearranging many taxa. Clarke et al (2018b) recognise only three of these new sections and also drop Danser's Nobiles which was lectotypified by Jebb (2015, 1999).…”

Nepenthaceae is one of the largest carnivorous plant families and features ecological and morphological adaptations indicating an impressive adaptive radiation. However, investigation of evolutionary and taxonomic questions is hindered by poor phylogenetic understanding, with previous molecular studies based on limited loci and taxa. We use high-throughput sequencing with a target-capture methodology based on a 353-loci, probe set to recover sequences for 197 samples, representing 151 described or putative Nepenthes species. Phylogenetic analyses were performed using supermatrix and maximum quartet species tree approaches. Our analyses confirm five Western outlier taxa, followed by N. danseri, as successively sister to the remainder of the group.We also find mostly consistent recovery of two major Southeast Asian clades. The first contains common or widespread lowland species plus a Wallacean-New Guinean clade. Within the second clade, sects. Insignes and Tentaculatae are well supported, while geographically defined clades representing Sumatra, Indochina, Peninsular Malaysia, Palawan, Mindanao and Borneo are also consistently recovered. However, we find considerable conflicting signal at the site and locus level, and often unstable backbone relationships. A handful of Bornean taxa are inconsistently placed and require further investigation. We make further suggestions for a modified infra-generic classification of genus Nepenthes.

“…Nepenthes diketahui sangat baik beradaptasi untuk tumbuh di tanah miskin hara yang memiliki unsur hara esensial seperti Nitrogen, Fosfor dan Kalium yang sangat rendah serta tingkat kemasaman tanah yang tinggi yang umumnya menjadi faktor pembatas bagi pertumbuhan tanaman (Bauer et al, 2008;Rembold et al, 2010;Cheek & Jebb, 2016). Tumbuhan ini tumbuh di berbagai karakter ekologi, mulai dari ketinggian 0-3500 m dpl, mulai dari rawa-rawa air tawar di pantai hingga pegunungan tinggi.…”

Penelitian ini bertujuan untuk mengetahui jenis Nepenthes di Kawasan Hutan Jalan Merek-Sidikalang, Lae Pondom, Merek, Kabupaten Karo, Provinsi Sumatera Utara. Metode penelitian ini menggunakan metode penelitian eksploratif. Penelitian dilakukan selama bulan November-Desember 2019. Hasil penelitian ditemukan dua jenis Nepenthes yaitu Nepenthes spectabilis Danser dan Nepenthes tobaica Danser. N. spectabilis Danser ditemukan pada ketinggian 1486- 1508 m dpl dengan suhu 23-250C dan N. tobaica Danser ditemukan pada ketinggian 1501-1510 m dpl dengan suhu 230C. Hasil identifikasi Nepenthes yang dilakukan berdasarkan rujukan dari buku-buku Flora of Java, Flora Malesiana, Nepenthes of Sumatra, Nepenthes of Borneo bahwa bentuk-bentuk morfologi kedua Nepenthes tersebut sangat berbeda berdasarkan morfologi batang, daun, kantong, akar dan bunga. Namun demikian, diperlukan penelitian lanjut terkait identifikasi Nepenthes dengan lokasi yang berbeda agar menjadi informasi tambahan.
