    Nepenthes epiphytica, a new Pitcher Plant from East Kalimantan

    A new species of Nepenthes L., N. epiphytica, from East Kalimantan, is described and illustrated. This new taxon is restricted to epiphytic montane ridge forest habitats on the scattered limestone mountains of the Berau and East Kutai Regencies of East Kalimantan. Nepenthes epiphytica shares some common features with certain members of the Nepenthes maxima complex, but can easily be distinguished from these by a number of consistent morphological and ecological differences.  / Key words: Nepenthes epiphytica​

    Nepenthes alfredoi (Caryophyllales, Nepenthaceae), A New Species of Pitcher Plant from Mindanao, Philippines

    The Philippines having the highest rates of endemism of this family is considered a center of diversity of the genus Nepenthes along with Sumatra and Borneo. Recent explorations in Mindanao and Luzon has raised the Philippine number of Nepenthes species to 52. This study reports the discovery of a new Nepenthes species from Mt. Hamiguitan. It is distinguished in having ground and upper pitchers with fringed wings on the tendril. The new species described herein was only observed at Gov. Generoso and has not been recorded elsewhere in the Philippines. Known only from the type locality and it faces severe threat from habitat destruction.  / Key words: Nepenthes alfredoi

    Nepenthes section Insignes in Indonesia, with two new species

    This paper is one in a series leading to a monograph of the genus Nepenthes building on a skeletal revision of the genus (Jebb & Cheek 1997) and the account for Flora Malesiana (Cheek & Jebb 2001). While in 2001 only 85 species were ac- cepted for the genus, today the figure lies at approximately 150. In 2013, 12 new species were published from the Philippines alone (Cheek & Jebb 2013a–g). In the last few years our at- tention has focussed on Indonesia, with new species described from Halmahera (Cheek 2015) and Sulawesi (Cheek & Jebb 2016 a – b). Here we describe a new species from New Guinea, the first published from that island since 2011 (Robinson et al. 2011: 543). / Key words: Nepenthes biak, nepenthes sp. Raja Apat

    Nepenthes leonardoi (Nepenthaceae), a New Pitcher plant Species from Palawan, Philippines

    ABSTRACT. A distinct Nepenthes from the upper slopes of Schom-carp Peak (Shumkat Peak, Shumkak Peak), on Palawan lsland in the Philip- pines, is described and illustrated. lt is the only Nepenthes species known from the upper slopes of Schom-carp Peak, and the easterly ridge top of the mountain extending towards the coast, and towards the outskirts of the town of Narra. Nepenthes leonardoi appears closely related to the morphologically similar species N. deaniana Macfarl., N. gantungensis S. McPherson, J. Cervancia, Chi. C. Lee, M. Jaunzems, F. Mey, A.S. Rob., and lV. mira Jebb & Cheek, but can be distinguished on the basis of its distinct leaf and pitcher morphol- ogy and growth habit. / Key words: Nepenthes leonardoi

    Two New Nepenthes Species from the Unexplored Mountains of Central Mindanao, Philippines

    ABSTRACT. Nepenthes L. is the sole genus of the family Nepenthaceae. Having the highest rate of endemism of this family, the Philippines is considered a center of diversity of the genus Nepenthes along with Sumatra and Borneo. Recent explorations in Mindanao and Luzon raised the number of Philippine Nepenthes species to 50. This study reports the discovery of two new Nepenthes species, N. malimumuensis and N. manobo in the unexplored region of the Pantaron range of central Mindanao making the range a home to eight species. Habitat destruction has the biggest impact on the population of Nepenthes spp. in the Pantaron range. The Pantaron range is not a protected area therefore the diversity, distribution, conservation and habitat preservation of the new endemic Nepenthes species reported herein need to be monitored closely. / Key words: Nepenthes malimumuensis, Nepenthes manobo

    Nepenthes barcelonae (Nepenthaceae), a new species from Luzon, Philippines

    Abstract. Nepenthes barcelonae is described as a new species in sect. Insignes, where it is unique in the inset mouth and the dichromic upper pitchers (first-produced pitchers red, later-produced pitchers green) which are also dimorphic. This is a newly recorded phenomenon in the genus: the first produced (primary upper pitchers) are red, larger, stouter, and have an uncoiled long tendril, while those later produced (secondary upper pitchers) are green, smaller, more slender, and have a coiled tendril. The only population of this species that is currently known grows in an area less than 10km2 on a single mountain. Individual plants are at risk from collecting for the horticultural trade. Following the IUCN criteria, N. barcelonae is assessed as Critically Endangered. / Key words: Nepenthes barcelonae

    Recircumscription of the Nepenthes alata group (Caryophyllales: Nepenthaceae), in the Philippines, with four new species

    An overview of Nepenthes in the Philippines is presented. Four new species, Nepenthes extincta sp. nov., N. kitanglad sp. nov., N. kurata sp. nov. and N. leyte sp. nov. are described and illustrated from the Philippines and placed in the Nepenthes alata group. An updated circumscription and key to the species of the group is provided. Delimitation and comparison with the Regiae group is given. All four of the newly described species are assessed as threatened using the International Union for the Conservation of Nature 2012 standard, and one, N. extincta sp. nov. is considered likely to be already extinct due to open-cast mining. Logging and conversion of forest habitat are thought to be the main threats to the other three species. /  Key words: Nepenthes kurata sp. nov., Nepenthes kitanglad sp. nov., Nepenthes extincta sp. nov., Nepenthes leyte sp. nov.

    Nepenthes (Nepenthaceae) of Halmahera, Indonesia

    Two new paniculate species of Nepenthes, N. halmahera and N. weda, both allied to N. danseri Jebb & Cheek, are described respectively from lowland and lower montane forest on ultramafic substrate. Nepenthes weda appears to be unique in the genus due to the adaxial tepal surfaces which in the distal portion are hairy and lack nectar glands. This species is also unique among paniculate members of the genus in its forward-facing, concave subapical lid appendage. Both species are currently only known from the Weda Bay Nickel Project concession area in Halmahera, Indonesia, and are assessed as Critically Endangered using the 2012 IUCN standard. Two character states are formally described and named for the first time in Nepenthes: nanophyll rosettes and multiseriate fringed pitcher wings. Stage-related heteromorphy in lid appendages is documented for the first time in the genus. Keys to the species of Nepenthes of Halmahera, and to the paniculate species of SE Asia are presented. / Key words: Nepenthes halmahera, N. weda

    Two New Nepenthes Species from the Philippines and an Emended Description of Nepenthes ramos

    With 50 species of the genus Nepenthes L. currently described from the Philippines, it is without doubt that the country, along with the islands of Sumatra (Indonesia) and Borneo (Indonesia, Malaysia, Brunei), should be considered the center of diversity of the genus. In this work, we describe two new species. One species, N. aenigma sp. nov., is from Ilocos Norte province on Luzon Island and has the—for Nepenthes—unusual ecological preference to grow in dense vegetation in deep shade. The other new species is from Mount Hamiguitan in Davao Oriental province on Mindanao Island. With this new entry, Mount Hamiguitan is now home to four endemic species (N. peltata, N. micramphora, N. hamiguitanensis, N. justinae sp. nov.). Furthermore, we provide an emended description of N. ramos based on field data. Nepenthes kurata is synonymized here with N. ramos. / Key words: Nepenthes aenigma, N. justinae

    Nepenthes alzapan (Nepenthaceae), a new species from Luzon, Philippines

    This paper forms a part of the studies towards a World Monograph of Nepenthes Linnaeus (1753: 955) building on a Skeletal Revision of Nepenthes (Jebb & Cheek 1997) and the Flora Malesiana account (Cheek & Jebb 2001). In the course of studying previously unseen specimens from the Philippines, four sheets (Ramos & Edanõ 45690, K, NY, UC, US), of a species previously unknown came to light from Mt Alzapan. The oblong, glabrous, ligulate, sessile leaf-blades with 5–7 pairs of nearly evenly spaced longitudinal nerves placed the species unambiguously in the Insignes group of Danser (1928) which is restricted to the Philippines apart from one species, N. insignis Danser (1928: 314), in New Guinea and, more ambiguously, N. northiana Hooker, J.D. (1881: 717) in Borneo (Cheek & Jebb 2001). The Insignes group are also characterised by more or less broadly cylindrical upper pitchers with a length: breadth ratio of 3 or 4:1 (constricted at the waist in N. ventricosa Blanco (1837: 807) which bear a broad peristome, semi-circular in section, the inner edge of which is prominently toothed, the outer attenuating in thickness until it is membranous. The lower surface of the pitcher lid lacks an appendage. The nectar glands are usually transversely elliptic, non-perithecoidal and are absent from the midline, being restricted to two incurved lateral bands. In the key to Philippine species of Nepenthes, Cheek & Jebb (2001) the species described below as N. alzapan, keys out as the small-pitchered N. bellii K.Kondo (1969: 653) of Mindanao. The two taxa appear similar in terms of overall dimensions of the pitchers. However, the upper pitchers of N. bellii, while broadly similar to those of N. alzapan, differ significantly in their finer peristome, and sparse lid glands (Table 1). In practice N. alzapan being restricted to Luzon, is unlikely to be confused with N. bellii, which is restricted to Mindanao. It is more likely that its leaves, stems and inflorescences might be identified as N. ventricosa, the only other species of this group in Luzon. However the upper pitchers of N. ventricosa are much larger and longer than in N. alzapan, 9–16 × 3–8cm and hour-glass shaped, lacking fringed wings, and the lid is narrowly elliptic 4–6 × 1.8–2.25 cm. / Key words: Nepenthes alzapan

    Recent explorations of the Barisan Range in Sumatra Barat have revealed the existence of at least two new taxa of Nepenthes (Clarke, 2001). One of these is described here as Nepenthes izumiae Troy Davis, C. Clarke & Tamin. This taxon was briefly discussed and illustrated as ‘Nepenthes species B’ by Clarke (2001). Nepenthes izumiae is characterised by its slender, cylindrical lower pitchers (≤ 35 cm in height), the outer surfaces of which are almost always heavily suffused with a dark purple pigment that makes them appear black in colour. The upper pitchers are also cylindrical, the outer surfaces being brownish purple. Both pitcher types possess a large, hook-shaped appendage on the lower surface of the pitcher lid. Nepenthes izumiae appears to be closely related to N. singalana Becc., another montane species which is common in West Sumatra and Jambi. However, it differs from this species in a number of characteristics. The most obvious of these is the hook- shaped appendage on the lower surface of the pitcher lid in N. izumiae, which is absent in N. singalana. However, it is found (in a less developed form) in pitchers of N. ovata Nerz & Wistuba and (occasionally) in pitchers of N. bongso Korth., both of which also occur in montane habitats in Sumatra. The latter species produces infundibular aerial pitchers (Jebb & Cheek, 1997), whereas those of N. izumiae are cylindrical throughout. Nepenthes izumiae also differs from N. singalana in that a number of simple, short, red-brown hairs are retained along the margins of the leaf blade, while the blades themselves are larger and broader. Table 1 outlines the principal differences between N. izumiae, N. singalana, N. bongso and N. ovata. Undoubtedly, N. singalana and N. izumiae are closely related, but the differences between them are both marked and stable. Accordingly, we feel that N. izumiae warrants distinction from N. singalana at specific rank. / Key words: Nepenthes izumiae

    Nepenthes ultra (Nepenthaceae), a new species from Luzon, Philippines

    This paper forms part of our studies towards our World Monograph of Nepenthes, building on our Skeletal Revision of Nepenthes (Jebb & Cheek 1997) and our Flora Malesiana account (Cheek & Jebb 2001). In an earlier paper we char- acterised and provided a key to the Nepenthes alata Blanco group of species which is confined to the Philippines (Cheek & Jebb 2013). In that paper we also reviewed morphological variation within Luzon of what had been considered as a single variable N. alata and showed that two distinct species exist, one in the northern submontane forests (N. alata) and another in the southern Luzon forests, extending to the Visayas and Mindanao (N. graciliflora Elmer). Among the 40 specimens of N. alata (in the wide sense) examined in preparing Cheek & Jebb 2013, two anomalous specimens were found which fitted neither N. alata nor N. graciliflora in morphology. They further differ in being plants of lowland coastal scrub on ultramafic substrates. We widened our search to additional herbaria and recovered additional sheets including three more specimen numbers, which agreed in morphology and ecology with the first two specimens. Following further study of the eleven specimen sheets now available, and after linking these specimens with photographic images of plants in habitat (Nickrent et al. 2006 onwards), we here describe this material as a new species. The main diagnostic differences between N. alata, N. graciliflora and our new species N. ultra are given in Table 1. In practice, N. ultra is unlikely to be confused with any other. It is the only lowland Nepenthes known in Luzon (below 400 m altitude), and is also the only species known to occur in ultramafic areas in Luzon.  / Key words: Nepenthes ultra

    Nepenthes samar (Nepenthaceae), a new species from Samar, Philippines

    This paper forms part of studies towards a World Monograph of Nepenthes, building on a Skeletal Revision of Nepenthes (Jebb & Cheek 1997) and the Flora Malesiana account (Cheek & Jebb 2001). In the course of studying previously unseen specimens from the Philippines, two collections (Gaerlan & Chavez 26372, 26416, both BRIT), of an unknown species, came to light from Samar in the eastern Visayas. The ligulate, sessile leaf-blades with 5 – 6 pairs of nearly evenly- spread longitudinal nerves placed the species in the Insignes group of Danser (1928) which are for the most part restricted to the Philippines (Cheek & Jebb 2001). Further characters that distinguish this group are given in Cheek & Jebb (2013).  The Samar material has only upper pitchers and not lower, which is also an attribute of two species of the Insignes group, N. ventricosa Blanco (1837: 807) which is found in Luzon and Panay, and N. burkei Mast. (1889: 492) which is found in Mindoro. In these two species, both of which are extensively cultivated, lower pitchers are produced either not at all or very rarely and inconspicuously before the plants develop upper pitchers (Cheek & Jebb 2001). Both these species have broadly cylindrical upper pitchers (as is usual in the group), but which are more or less constricted at the middle, while the Samar material has cylindrical to narrowly infundibular upper pitchers. Nepenthes merrilliana Macfarl. (1911: 207) of Surigao Province in NE Mindanao is the species of the Insignes group closest geographically, and in overall dimensions, to the Samar spe- cies. However, of the 12 specimens known of N. merrilliana only one features upper pitchers, the remainder bearing only lower pitchers, including those with inflorescences, suggesting that upper pitchers are produced infrequently in this species, the opposite of the case in the Samar material. The two species differ further, in leaf-blade, pitcher, and inflorescence characters as shown in Table 1. Accordingly, N. samar is here described as new to science. / Key words: Nepenthes samar

    Nepenthes minima is the first known pyrophytic grassland Nepenthes species from outside Indochina and the Philippines. A member of the sect. Regiae (Borneo, Wallacea, New Guinea) it is restricted to the highland grasslands of Central Sulawesi (Celebes) and has close affinities with Nepenthes maxima. The existence of Nepen- thes minima, unique to these grasslands, suggests that they may be natural and predate the human influences that expanded them beginning 2000–3000 BP. / Key words: Nepenthes minima

    The Nepenthes micramphora (Nepenthaceae) group, with two new species from Mindanao, Philippines

    The N. micramphora group is erected to accommodate the species N. micramphora, N. abgracilis sp. nov. and N. cid sp. nov. from submontane habitats in Mindanao, Philippines. An overview of the genus in the Philippines is presented in the context of recent discoveries. The greater taxonomic importance of pitcher characters over those of the flowers in the genus is reviewed and hypotheses are provided to account for this phenomenon.  / Key words: Nepenthes micramphora, N. abgracilis sp. nov., N. cid sp. nov.

    Four New Species of Nepenthes L. (Nepenthaceae) from the Central Mountains of Mindanao, Philippines

    Together with the islands of Sumatra (Indonesia) and Borneo (Indonesia, Malaysia), the Philippines are the main center of diversity for carnivorous pitcher plants of the genus, Nepenthes L. Nepenthes are the largest of all carnivorous plants, and the species with the biggest pitchers are capable of trapping and digesting small amphibians and even mammals. The central cordillera of Mindanao Island in the south of the Philippines is mostly covered with old, primary forest and is the largest remaining cohesive, untouched area of wilderness in the Philippines. In a recent field exploration of two areas of the central cordillera, namely Mount Sumagaya and a section of the Pantaron range, four new taxa of Nepenthes were discovered. These four remarkable new species, N. pantaronensis, N. cornuta, N. talaandig and N. amabilis, are described, illustrated and assessed.  / Key words: Nepenthes pantaronensis, N. cornuta, N. talaandig, N. amabilis

    A spectacular new species of Nepenthes L. (Nepenthaceae) pitcher plant from central Palawan, Philippines


    A new species of Nepenthes L., N. attenboroughii (Nepenthaceae), from Palawan Island in the Philippines, is described and illustrated. It is restricted to rocky, ultramafic soils that comprise the summit region of Mount Victoria, Municipality of Narra, where it occurs in isolation from other members of the genus. On the basis of the morphological features, this new taxon appears to be related to both N. mira Jebb & Cheek of Palawan and N. rajah Hook.f. of Borneo. Its substantial size places it among the largest of known pitcher plants. The diagnostic morphological characters are discussed and an updated key is provided for a revised complex of Nepenthes species from the Palawan and North Borneo phytogeographical region. / Key words: Nepenthes attenboroughii

    Nepenthes flava, a New species of Nepenthaceae from the Northern part of sumatra

    in terms of the number of known Nepenthes species the flora of sumatra is one of the richest in the world. in recent years several new species have been discovered and described, such as Nepenthes adnata tamin & hotta ex schlauer, N. angasanensis r. Maulder, d. schub., B. salmon & B. Quinn, N. aristolochioides Jebb & cheek, N. diatas Jebb & cheek, N. lavicola Wistuba & rischer, N. longifolia nerz & Wistuba, N. mikei B. salmon & r. Maulder, N. tenuis nerz & Wistuba, N. jacquelineae and N. xiphioides B. salmon & r. Maulder (nerz & Wistuba, 1994; Jebb & cheek, 1997; clarke, 2001). the number of known sumatran species is even higher than the number of Bornean species, thus sumatra certainly can be called a hotspot of evolution of nepenthaceae. it can be assumed that some members of Nepenthes may have evolved quite recently; many species like N. singalana Becc. and N. bongso Korth. are quite variable and are closely related to each other. some of the species however have very distinct and unique characteristics, such as e.g. the rimless N. inermis or the recently discovered N. jacquelineae with its monstrous peristome (clarke, 2001). A new spe- cies of Nepenthes that had been discovered on a mountain in northern sumatra is now described from cultivated material... / Key words: Nepenthes flava

    Nepenthes baramensis (Nepenthaceae) – a new species from north-western Borneo

    Abstract: Nepenthes baramensis, a new species from peat swamp and heath forests in north-western Borneo, is described. It is distinguished from related species on the basis of its modified pitchers, which facilitate a faculta- tive mutualistic interaction with Hardwicke’s Woolly Bat, Kerivoula hardwickii, which roosts in its pitchers and may provide the plant with a substantial proportion of its foliar nitrogen. / Key words: Nepenthes baramensis

    Nepenthes nebularum, a new species from Mindanao, Philippines

    Abstract: The discovery of Nepenthes nebularum sp. nov. is here reported and thereby described as a new addition to the Philippine Nepenthes flora. This new species is closely related to both N. trun- cata and N. robcantleyi, differing mainly in the smaller stature of the plants, the more pronounced peristome teeth, and the bronzy, rather dense, and woolly indumentum found on the petiole wings, tendrils and traps. Further distinguishing traits are discussed in the description proper. With the description of this new species, the number of Nepenthes species in the archipelago now stands at over 53. / Key words: Nepenthes nebularum
