Tentaculatae, confirming the previous morphologically-based sectional placement of these species (Cheek et al, 2018Cheek and Jebb, 2016a;Nerz et al, 2011bNerz et al, , 2011a). The affinities of N. undulatifolia were considered unclear when the species was described (Nerz et al, 2011b) but was included in sect.…”

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.

“…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.…”

“…Wilayah Maluku terdapat 3 jenis endemik, dan di Papua ditemukan 11 jenis, 7 jenis di antaranya merupakan jenis endemik (Mansur, 2013). Populasi Nepenthes terancam oleh pembukaan lahan, tambang, pengambilan berlebihan di habitat asli, dan perdagangan ilegal (Cheek, 2015;Cheek et al, 2018 Salah satu jenis yang sulit ditemui di alam adalah Shorea platyclados. Jenis ini menjadi terancam punah karena habitat aslinya terdegradasi oleh pembukaan hutan sehingga tidak memungkinkan untuk pertumbuhan populasi.…”

One of the main task of Cibodas Botanical Garden (CBG) is to conserve the Indonesian plants species. Moreover, the preservation and enrichment of threatened plant collections based on IUCN red list categories became an important programme for plants conservation in CBG. The aims of this study are to inventory threatened plant collections and to review the status of CBG threatened plant collections. List of threatened plant collections was gathered from SINDATA, a system developed by CBG. The collection, was reviewed by inspecting current collections in CBG. Literature study was done to review the conservation status of the threatened plant collections. The conservation status was checked in IUCN red list website. The results shown that CBG had collected 86 species of threatened plants, which is 13 Critically Endangered (CR) species, 39 Endangered (EN) species, and 34 Vulnerable (VU) species. Critically endangered category consists of 13 species belong to 8 families and 10 genus. Endangered category consists of 39 species belong to 17 families and 34 genus. Vulnerable category consists of 34 species belong to 27 families and 28 genus. The largest collections of threatened species was genus Nepenthes, which is 16% (14 species) from the total threatened species in CBG. Furthermore, CBG had succeeded in collecting 40 species of Indonesian native plants in which Dipterocarpaceae species were dominate the collection with 7 species. These species are listed as critically endangered (3 species) and endangered (4 species).

“…However, new species of Nepenthes continue to be discovered elsewhere in SE Asia, from Indonesia, with new species described from Halmahera ( Cheek, 2015 ), Sulawesi ( Cheek & Jebb, 2016a , 2016b ) and New Guinea ( Cheek et al, 2018 ), and also from Malaysia, with new species from Borneo ( Robinson et al, 2019b ; Golos et al, 2020 ).…”

Nepenthes maximoides sp. nov. (Sect. Alatae) is described and assessed as Critically Endangered (Possibly Extinct) from Luzon, Philippines and appears unrecorded in 110 years. The spectacular, large, narrowly funnel-shaped upper pitchers, lids with recurved basal and filiform apical appendages, unlike any other species in the Philippines, closely resemble those of N. maxima (Sect. Regiae) of Sulawesi–New Guinea, likely due to convergent evolution. Following recent phylogenomic analysis, sect. Alatae is divided into two, Sect. Alatae sensu stricto of Luzon to Sibuyan (including N. maximoides), and Sect. Micramphorae, expanded and recircumscribed to encompass those species of the southern Visayas, and Mindanao. A key is provided to the six species now recognised in the newly narrowly recircumscribed Sect. Alatae. The number of Nepenthes species recorded from Luzon has increased from two in 2001, to eight in 2020, all but one of which are endemic to that island, and four of which appear to be point endemics.
