Nepenthes bokorensis /nɪˈpɛnθiːz ˌbɒkɒˈrɛnsɪs/ is a tropical pitcher plant endemic to Cambodia. It is known from Mount Bokor (also Phnom Bokor or Bokor Hill) in the south of the country, and an as yet undetermined specimen suggests that it may also be present in other parts of the Dâmrei Mountains of Kampot Province. The specific epithet bokorensis refers to both Mount Bokor and Bokor National Park.[1]
Despite only being formally described in 2009, N. bokorensis has been known since at least the early 20th century. The oldest known herbarium specimens are three taken by French plant collector C. Geoffray on January 14, 1904.[note a] Two of these consist of lower pitchers with leaves, while the third comprises upper pitchers with leaves. All three specimens were collected from Popokvil falls, Mount Bokor, and are deposited at the Museum National d'Histoire Naturelle in Paris.[1]
The next known collection of this species was made by J. E. Vidal in 1965.[note b] It consists of a plant with upper pitchers. Three years later, Marie Martin collected M. Martin 1231bis,[note c] which includes lower pitchers and female floral material. Further herbarium material,[note d] consisting of two rosette plants, was collected by David Middleton and Meng Monyrak in 2001.[1]
In July 2007, François Sockhom Mey found N. bokorensis on Mount Bokor during a field trip to southern Cambodia. He posted photographs of the species on a number of online message boards the following month.[1] Mey formally described[note e] the species in the March 2009 issue of Carniflora Australis, the journal of the Australasian Carnivorous Plant Society.[1] M. Martin 1231bis, deposited at the Museum National d'Histoire Naturelle, was designated as the holotype.[1]
A specimen collected by Auguste Jean Baptiste Chevalier in 1917[note f] may also represent this species and if confirmed as such would increase the known range of N. bokorensis to include other parts of the Dâmrei Mountains.[1] Material deposited at Forest Herbarium, Bangkok (BKF)[note g] and identified as N. thorelii likely also belongs to N. bokorensis.[1]
Nepenthes bokor, described by Martin Cheek in June 2009,[2] is a later synonym of N. bokorensis.[3][4]
In August 2011, François Mey and Alastair Robinson discovered two large new populations of N. bokorensis on the Mount Bokor massif, which they called "Location B" and "Location C" (the original roadside population being "Location A").[5][6][7][8]
Nepenthes bokorensis is a climbing plant, attaining a height of up to 7 m. In rosettes and on lower parts of the plant, the stem is up to 0.9 cm thick and circular in cross section. On climbing parts, the stem is terete and measures up to 1 cm in diameter. Internodes are around 3 cm long.[1]
Leaves are sessile to sub-petiolate and coriaceous (leathery) in texture. The lamina or leaf blade is oblong to linear-lanceolate in shape and measures up to 35 cm in length by 8 cm in width. Its apex varies greatly, ranging from acute to obtuse and it may sometimes also be acuminate. The lamina is attenuate at the base, clasping the stem by around three-quarters of its circumference and rarely becoming decurrent. Three longitudinal veins are present on either side of the midrib. Pinnate veins originate obliquely from the midrib. Tendrils are up to 18 cm long and 2 mm in diameter. Those produced on upper parts of the stem may be coiled.[1]
Rosette and lower pitchers measure up to 20 cm in height by 6 cm in width. They are ovate in the basal third, before narrowing to become cylindrical or slightly infundibular towards the peristome. A pair of fringed wings (≤15 mm wide) runs down the ventral surface of the pitcher cup. Fringe elements are up to 12 mm long. The pitcher mouth has an oblique insertion. The peristome is approximately cylindrical and may be up to 20 mm wide. It bears ribs (≤0.8 mm high) spaced up to 1 mm apart. The pitcher lid or operculum is orbicular to broadly elliptic in shape, has a cordate base, and measures up to 7 cm in length by 6 cm in width. The underside of the lid lacks appendages, but bears numerous, densely packed crater-like glands. Those concentrated along the midrib reach the greatest dimensions (≤0.5 mm in diameter), while the rest are much smaller (0.2 to 0.3 mm in diameter) and more sparsely distributed. A spur measuring up to 12 mm in length is inserted near the base of the lid. It is typically unbranched, but may also be bifurcate.[1]
Upper pitchers exhibit great variability in both form and colouration,[9] but generally grow to 25 cm in height by 6 cm in width. They are infundibular throughout, becoming narrower in the basal portion. Wings are reduced to ribs in these aerial pitchers. The peristome is up to 17 mm wide and often somewhat flared at the margins. The peristome ribs are less developed than in lower pitchers, measuring only up to 0.4 mm in height, and spaced only up to 0.5 mm apart. The lid is similar to that found in terrestrial traps, although slightly smaller (up to 6 cm long by 5 cm wide) and often bearing a revolute margin. Other parts of upper pitchers are similar to their lower counterparts.[1]
Nepenthes bokorensis has a racemose inflorescence measuring up to 100 cm in length. It bears up to 80 flowers borne on one-flowered pedicels (≤9 mm long), or rarely two-flowered partial peduncles. In male plants, the peduncle reaches 70 cm and the rachis 30 cm, while female plants produce a rachis up to 20 cm long. Tepals are orbicular to elliptic, ranging in length from 2 mm in male flowers to 4 mm in female flowers. The former have androphores up to 2 mm long, while the latter bear ovaries around 4 mm long. Fruit are typically 10 to 25 mm long and each contain 50 to 100 fusiform seeds measuring around 7 mm in length.[1]
All vegetative and floral parts of N. bokorensis bear an indumentum of silvery or brownish hairs up to 1 mm long. In some places this covering may be reduced, giving an almost glabrous appearance.[1]
It is not certain whether N. bokorensis produces a well-developed rootstock like other Indochinese species, but observations of cultivated plants suggest that this is likely to be the case.[1]
Nepenthes bokorensis is known with certainty only from the Mount Bokor massif in Bokor National Park, Kampot Province, Cambodia, where it has an altitudinal distribution of 800–1080 m above sea level.[1] Three populations are known from the mountain.[5] An as yet undetermined specimen (Aug. Chevalier 36411)[note f] suggests that the species may also be present in other parts of the Dâmrei Mountains.[1]
The typical habitat of this species is seasonally dry upland scrub. It also grows in stunted lower montane forest under sparse tree cover. Plants growing in exposed sites under direct sunlight are very stunted and often flower when less than 60 cm tall.[1] The species attains much greater heights under the shade of surrounding vegetation.[1] Natural hybrids with N. kampotiana have been recorded.[10]
In open areas, N. bokorensis is sometimes sympatric with other carnivorous plants, including sundews and bladderworts.[11] The N. bokorensis plants found by François Mey in 2007 grew alongside a crimson form of Drosera peltata, but this population was destroyed by the time of the author's return in 2009.[12] Drosera peltata still grows sympatrically with N. bokorensis at "Location C", a massive clearing discovered in 2011 on the Bokor plateau.[11] The D. peltata plants at this site range in colour from yellowish-green to red and frequently exceed 30 cm in height.[11] Nepenthes bokorensis also shares this habitat with another sundew—D. burmannii—as well as with various grasses, stunded shrubs, and lithophytic orchids.[11] Local bladderwort species include U. bifida, U. odorata, U. minutissima, U. striatula, U. subulata, and U. uliginosa.[13][14][15][16]
On Mount Bokor, the species grows on sandy, acidic soils. The substrate has a pH of 4.6 according to the herbarium label of Middleton & Monyrak 589.[note d][1]
The prey assemblage of N. bokorensis appears to consist primarily of ants.[1][17] A 2012 study recorded 10 ant species, representing 9 genera and 3 subfamilies, from 30 N. bokorensis pitchers in Bokor National Park.[17] Polyrhachis (Myrma) sp. was found to be the most abundant taxon, accounting for 40% of all specimens, followed by Dolichoderus thoracicus and Camponotus (Tanaemyrmex) sp.[17] The authors suggested that the relatively large-bodied members of the genera Camponotus and Polyrhachis may be of particular importance to the plant in terms of nutrient intake.[17] Also among the prey assemblage of N. bokorensis was the tramp species Cardiocondyla wroughtonii (actually a species complex).[17]
The ant-trapping habit of N. bokorensis is reflected in the local Khmer name for the plant, ampuong sramoch, which means "ants' pithole".[1] This name is not specific to N. bokorensis but refers to Nepenthes in general, and is used in Kampot Province and the town of Pursat.[1]
The pitcher fluid of this species is strongly acidic; the label on the herbarium specimen Middleton & Monyrak 589[note d] states that it has a pH of 2.7.[1]
Cambodia ranks among the countries with the highest deforestation rates worldwide.[1] Despite this, the habitat of N. bokorensis remained relatively undisturbed until 2009, lying as it did within the boundaries of Bokor National Park.[1] At the time, François Mey assessed the conservation status of N. bokorensis as "potentially vulnerable" based on the IUCN criteria, citing increasing tourism and land development as potential threats (Mount Bokor had been leased for private development by the government of Cambodia).[1] Habitat loss accelerated rapidly in the following two years as work on the massive "Bokor City" project began in earnest.[18][19][20] As of 2011, both the type population and the two newly discovered sites are threatened by the ongoing development.[18][19]
Recently, a new threat has been identified. People, particularly women, have taken to picking the plants and having their photos taken with them because while the leaves are still developing, the mouths of the plants resemble men's genitalia. The Cambodian Ministry of Environment has taken to social media to plead with the public to stop picking the plants, which it says could be driven to extinction if people continue to harvest them, as the pitchers allow the plants to obtain nutrients they cannot obtain otherwise.[21]
Nepenthes bokorensis is most closely allied to several other Indochinese pitcher plants, particularly N. kampotiana, N. smilesii, and N. thorelii.[1] It can be distinguished from all three on the basis of its wider, more oblong-shaped lamina and occasional two-flowered partial peduncles.[1]
The indumentum of N. bokorensis is also distinctive, and distinguishes it from N. kampotiana, which typically has glabrous leaves. Compared to N. smilesii, N. bokorensis has more robust and colourful pitchers with a broader peristome and longer tendrils. The species differs from the enigmatic N. thorelii in several aspects of vegetative morphology. Firstly, the lamina of N. bokorensis is sessile to sub-petiolate and only slightly decurrent down the stem, if at all.[1] In comparison, N. thorelii has an amplexicaul leaf attachment and the base of the lamina is decurrent into two wings that extend up to 2.5 cm down the stem.[22] In addition, N. thorelii has wholly ovoid lower pitchers,[22] whereas those of N. bokorensis are only ovate in the basal third, becoming cylindrical above.[1]
Nepenthes bokorensis also appears to be closely related to N. kerrii of Thailand.[23] It can be distinguished from this species on the basis of its laminae, which are linear to lanceolate as opposed to obovate in the latter. It also differs in having a variable indumentum covering all vegetative and floral parts. In contrast, the indumentum of N. kerrii is restricted to the leaf axils. The androphore of N. kerrii is also considerably shorter than that of N. bokorensis.[23]
N. thorelii Lecomte simile, sed foliis longioris latioris oblongis sessilibus vel subpetiolatis basaliter amplexicaulibus peristomio robusto cylindrico pedicellis interdum 2-floribus differt.
Nepenthes bokorensis /nɪˈpɛnθiːz ˌbɒkɒˈrɛnsɪs/ is a tropical pitcher plant endemic to Cambodia. It is known from Mount Bokor (also Phnom Bokor or Bokor Hill) in the south of the country, and an as yet undetermined specimen suggests that it may also be present in other parts of the Dâmrei Mountains of Kampot Province. The specific epithet bokorensis refers to both Mount Bokor and Bokor National Park.

Nepenthes bokorensis is een vleesetende bekerplant uit de familie Nepenthaceae. De soort is endemisch in Cambodja. Hier komt hij voor op de berg Phnom Bokor in het nationaal park Preah Monivong Bokor. De plant is zowel naar de berg als het park vernoemd.[1]
Nepenthes bokorensis vangt voornamelijk mieren. De lokale naam in het Khmer luidt dan ook ampuong sramoch, wat 'mierenvalkuil' betekent. In de provincie Kampot wordt deze naam overigens op alle Nepenthes-planten toegepast.[1]
Nepenthes bokorensis is een klimplant die een hoogte van zeven meter kan bereiken. De plant is geheel bedekt met zilverkleurige of bruinige haartjes. De bladeren worden maximaal 35 centimeter lang en 8 centimeter breed. De ranken die de bladeren met de vangbekers verbinden zijn tot 18 centimeter lang.[1]
De onderbekers zijn tot 20 centimeter hoog en 6 centimeter breed. De bovenbekers meten tot 25 centimeter hoog en 6 centimeter breed[1] en vertonen een grote verscheidenheid in vorm en kleur.[2] De bekervloeistof is zeer zuur; bij een plant werd een pH-waarde van 2,7 gemeten.[1]
Nepenthes bokorensis is endemisch in Cambodja. Hij komt met zekerheid voor op de berg Phnom Bokor in het nationaal park Preah Monivong Bokor, waar hij is aangetroffen op hoogtes tussen de 800 en 1080 meter boven zeeniveau. Mogelijk bestaan er ook populaties in andere delen van het Damreigebergte.[1]
Het typische leefgebied van Nepenthes bokorensis bestaat uit droog kreupelhout of onvolgroeide hellingbossen. De plant groeit optimaal in de schaduw van andere vegetatie; in direct zonlicht zal ze meestal onvolgroeid blijven.[1] N. mirabilis en N. kampotiana zijn sympatrische soorten op Phnom Bokor. Van de laatstgenoemde bekerplant zijn natuurlijke hybriden met N. bokorensis waargenomen.[3]

波哥猪笼草（学名：Nepenthes bokorensis）是柬埔寨特有的热带食虫植物。其存在于柬埔寨南部的波哥山（Mount Bokor），也可能存在于贡布省象山山脉的部分地区。波哥猪笼草的种加词“bokorensis”即来源于波哥山及波哥国家公园。[1]
虽然波哥猪笼草于2009年才被正式描述，但其早在20世纪初就被发现了。已知最早的波哥猪笼草标本是由法国植物采集者C·若弗雷（C. Geoffray）于1904年1月14日在波哥山的双重瀑布（Popokvil falls）附近采集到的三粉标本。[注 1]其中两份标本由带下位笼的叶片组成，第三份由带上位笼的叶片组成。这三份标本存放于法国国家自然历史博物馆。[1]
1965年，J·E·维达尔（J. E. Vidal）第二次采集了波哥猪笼草的标本。其由一个带上位笼的植株组成。[注 2]三年后，玛丽·马丁（Marie Martin）采集了编号为“M. Martin 1231bis”的标本，其中含有下位笼和雌性的花序。[注 3]2001年，大卫·米德尔顿（David Middleton）和孟·摩尼拉克（Meng Monyrak）采集了带两棵莲座状植株的标本。[1][注 4]
2007年7月，弗朗索瓦·萨克洪·梅（François Sockhom Mey）在对于柬埔寨南部的实地考察中，于波哥山发现了波哥猪笼草。几个月后，他在网上公布了大量关于波哥猪笼草的照片。[1]2009年3月，他在澳大利亚食虫植物协会的《澳大利亚食虫植物》中正式描述[注 5]了波哥猪笼草。并将存于法国国家自然历史博物馆的编号为“M. Martin 1231bis”号标本为指定为模式标本。[1]
此外，奥古斯特·让·巴蒂斯特·谢瓦利埃在1917年[注 6]采集到的标本也可能是波哥猪笼草。如果这被证实，那么说明波哥猪笼草还存在于象山山脉的部分地区。[1]曼谷森林植物标本馆（BKF）[注 7]中被鉴定为高棉猪笼草（N. thorelii）的标本可能也属于波哥猪笼草。[1]
2009年6月，马丁·奇克也描述了这个物种，并将其命名为“Nepenthes bokor”[2]，其后来被认为是波哥猪笼草同物异名。[3][4]
2011年8月，弗朗索瓦·梅和阿拉斯泰尔·罗宾逊一起在波哥山发现了两个波哥猪笼草的巨大分布地，其被命名为“Location B”和“Location C”（原位于路边的分布地被命名为“Location A”）。[5][6][7][8]
波哥猪笼草为藤本植物，其可攀爬至7米的高处。莲座状植株及成年植株的下部，茎直径可达0.9毫米，呈圆柱形。攀援部分的茎直径可达1厘米。节间距可达3厘米。[1]
波哥猪笼草的叶片无柄至具小叶柄，革质，呈披针形或线形－披针形，可长达35厘米，宽至8厘米。叶片末端可变性较大，可为急尖至钝尖，偶尔可能为渐尖。叶片渐缩至基部，包裹住茎部周长的四分之三，极少下延。中脉的两侧各有3条纵脉。羽状脉斜发于中脉。笼蔓可长达18厘米，直径至2毫米。上位笼的笼蔓可出现笼蔓圈。[1]
波哥猪笼草的下位笼可高达20厘米，宽至6厘米。其下三分之一为卵形，上部缩小为圆柱形或略呈漏斗形。腹面具一对毫米的笼翼，不宽于15毫米。翼须可长达12毫米。笼口倾斜。唇为圆柱形，可宽达20毫米。唇肋间距1毫米，可高达0.8毫米。笼盖为圆形至椭圆形，基部为心形，可长达7厘米，宽至6厘米。笼盖的下表面无附属物，但具有密集的火山口状蜜腺。靠近中线的蜜腺体型最大，直径可达0.5毫米；其余部分的蜜腺较小，且分布较稀疏，直径为0.2至0.3毫米。笼盖基部的后方有一根可长达12毫米的笼蔓尾，其通常不分叉。[1]
波哥猪笼草的上位笼的可变性较大，其可高达25厘米，宽至6厘米，呈漏斗形，基部较窄。笼翼缩小为一对隆起。唇可宽达17毫米，边缘平展。唇肋不如下位笼发达，高仅可达0.4毫米，间距仅为0.5毫米。笼盖与下位笼相似，但略小。其可长达6厘米，宽至5厘米，边缘常呈波浪形。其他部分与下位笼类似。[1]
波哥猪笼草的花序为总状花序，可长达100厘米。一个花序可具80朵花。大部分花梗带一朵花，极少数花梗带两朵花。雄性花序的总花梗可长达70厘米，花序轴可长达30厘米。而雌性花序的花序轴只可达20厘米。花被片为圆形至椭圆形，雄性花序的花被片可长达2毫米，雌性花序的可长达4毫米。雄蕊柄可长达2毫米，子房长约4毫米。果荚通常长10至25毫米，含50至100个梭形的种子，其长约7毫米。[1]
波哥猪笼草所有的营养组织都披被着银色或褐色的毛被，其可长达1毫米。部分位置的毛被较为稀疏，使之看起来似乎无毛。[1]
还不能肯定波哥猪笼草是否具有类似于其他中南半岛地区猪笼草那样发达的根系，但栽培观察表明很可能如此。[1]
仅确定波哥猪笼草分布于柬埔寨贡布省波哥山海拔800米至1080米处。一个尚未确定的标本（Aug. Chevalier 36411）表明波哥猪笼草也可能存在于象山山脉的部分地区。[1]
波哥猪笼草的典型原生地是季节性干旱的高地灌木丛。其也生长于矮小的低地山区森林内。波哥猪笼草生长于有充足直射光的开阔地区，所以植株常矮化，开花时整个植株也很少超过60厘米。还未发现波哥猪笼草与其他猪笼草同域分布，也未发现波哥猪笼草的自然杂交种。[1]
在一些开阔地，波哥猪笼草有时还与其他食虫植物同域分布，如茅膏菜和狸藻。[9]2007年，弗朗索瓦·梅找到的波哥猪笼草与盾叶茅膏菜（Drosera peltata）的红色变型生长于一起，但作者在2009年返回时，原生地已被破坏。[10]2011年于波哥高原（Bokor plateau）波哥猪笼草原生地“Location C”也发现的盾叶茅膏菜与之同域分布。盾叶茅膏菜颜色的可变性较高，可为黄绿色至红色，高度常超过30厘米。此外，波哥猪笼草还与锦地罗，及各种禾本科植物、低矮灌木和岩生兰花同域分布。[9]当地的狸藻物种包括兩裂狸藻（U. bifida）、芳香狸藻（U. odorata）、斜果狸藻（U. minutissima）、圆叶狸藻（U. striatula）、尖葉狸藻（U. subulata）和溼地狸藻（U. uliginosa）。[11][12][13][14]
在波哥山上，波哥猪笼草生长于酸性的砂质土壤中。根据“Middleton & Monyrak 589”号标本的标签显示，其生长的基质pH值约为4.6。[1][注 4]
波哥猪笼草的猎物主要为蚂蚁。[1][15]2012年一项对波哥国家公园内30个波哥猪笼草捕虫笼的研究显示，其内存在着3个亚科9个属的10种蚁类。[15]多刺蚁（Polyrhachis (Myrma) sp.）是数量最多的类群，约占所有样本的40%，其次为黑可可臭蚁（Dolichoderus thoracicus）和弓背蟻（Camponotus (Tanaemyrmex) sp.）。[15]其研究者认为多刺蚁和弓背蚁可能是波哥猪笼草特别重要的营养来源。[15]
这反映在当地高棉语猪笼草的名称中，贡布省和菩萨市的当地人将其被称为“ampuong sramoch”，意为“蚂蚁坑”。但这个名字并不是特指波哥猪笼草，而是指当地的所有猪笼草。[1]
波哥猪笼草捕虫笼内的消化液为强酸性，“Middleton & Monyrak 589”号标本的标签写道其消化液的pH值可低至2.7。[1][注 4]
波哥猪笼草与其他存在于中南半岛的猪笼草之间存在着密切的近缘关系，特别是贡布猪笼草（N. kampotiana）、斯迈尔斯猪笼草（N. smilesii）和高棉猪笼草。波哥猪笼草与这三者的区别在于其叶片较宽，更接近椭圆形，且其花序偶尔具有带两朵花的花梗。[1]
波哥猪笼草与贡布猪笼草的区别在于，贡布猪笼草的叶片通常无毛。相对于斯迈尔斯猪笼草，波哥猪笼草的捕虫笼质地更坚硬，颜色更丰富，且具有较宽的唇和较长的笼蔓。波哥猪笼草与高棉猪笼草的营养组织有几个方面的不同。首先，波哥猪笼草的叶片无柄至具小叶柄，仅略微的下延。[1]而高棉猪笼草的叶片包住茎部，且叶片的基部下延成两个可宽达2.5厘米的叶柄翼。[16]此外，高棉猪笼草具有卵形的下位笼[16]，而波哥猪笼草的下位笼仅下三分之一为卵形，其余的上部为圆柱形。[1]
波哥猪笼草也表现出与产自泰国的克尔猪笼草（N. kerrii）之间存在着密切的近缘关系。[17]波哥猪笼草与克尔猪笼草的区别在于波哥猪笼草叶片为线形至披针形，而克尔猪笼草的叶片为倒卵形。波哥猪笼草周身具有毛被，而克尔猪笼草的毛被只存在于叶腋。此外，克尔猪笼草的雄蕊柄也短于波哥猪笼草。[17]
虽然柬埔寨是世界上森林開伐率最高的国家之一，但波哥猪笼草的分布地的环境还相对未受破坏。[1]当时，弗朗索瓦·梅依据世界自然保护联盟的标准，认为波哥猪笼草“潜在易危”。[1]虽然波哥猪笼草生长于波哥国家公园中，但其仍然受到当地旅游业发展的威胁。柬埔寨政府已将波哥山租赁予私人以修建度假村和高尔夫球场。[1]虽然开发商表示会重视环境保护，但波哥山上仍有大片的森林遭到破坏。[18]“波哥城”项目建设使波哥猪笼草的原生地加速消亡。[19][20][21]截至2011年，波哥猪笼草的模式产地及新发现的原生地都依然受到当地不断开发的威胁。[19][20]

波哥猪笼草（学名：Nepenthes bokorensis）是柬埔寨特有的热带食虫植物。其存在于柬埔寨南部的波哥山（Mount Bokor），也可能存在于贡布省象山山脉的部分地区。波哥猪笼草的种加词“bokorensis”即来源于波哥山及波哥国家公园。
