==Botanical history==
[[File:Nepenthes vieillardii.gif|thumb|left|Figure 26 from "[[The Nepenthaceae of the Netherlands Indies]]" showing a portion of a climbing stem with a male inflorescence (''Pulle 843 bis''; labelled '''a''') and dwarf plants from the mountain top (''Lam 1654''; labelled '''b''' and '''c''').<ref name=Danser />]]
===Early collections===
<!--The first known [[herbarium]] collections of ''N. lamii'' were made in the early 20th century. {{Ill|nl|Lucien Sophie Albert Marie von Römer|Lucien Sophie Albert Marie von Römer}} made one of the earliest collections of this species in November 1909. This specimen, designated as ''Von Römer 1037'', was collected at 1460 m and includes female floral material.<ref name=Danser /> The duplicate collections ''Von Römer 1038'' and ''Von Römer 1052'' were collected at the same time and place, but lack floral material.<ref name=Danser />
The next known collections of ''N. lamii'' were made from the [[Hellwig Mountains]] by [[August Adriaan Pulle]]. On December 23, 1912, he collected ''Pulle 802'' and ''Pulle 803'' from [[Mount Erica]] at an elevation of 1520 m. ''Pulle 802'' includes male floral material and is also preserved in [[alcohol]], whereas ''Pulle 803'' has no floral parts.<ref name=Danser /> Four days later, on December 27, 1912, Pulle collected ''Pulle 843 bis'', a male specimen, from an unspecified ___location in the Hellwig Mountains at an elevation of 1900 m.<ref name=Danser /> Both the specimens of von Römer and Pulle comprise very small and delicate plants.<ref name=C&J />-->
[[Herman Johannes Lam]], after whom the species is named, made a number of collections of ''N. lamii'' during the [[Van Overeem Expedition]] of 1920.<ref name=McPherson /><ref name=monticola /><ref name=C&J /> He collected both male and female floral material on October 17, 1920, on the flanks of [[Doorman Top]] (now known as [[Mount Anggemuk]]), [[West_Papua_(province)|West Papua]], at an elevation of 3,250 m<ref name=Danser /> (or 3,200 m).<ref name=J&C /><ref name=C&J /> These specimens are collectively designated as ''Lam 1637''.<ref name=Danser /> Lam made a further collection of ''N. lamii'' on the following day, October 18, this time from 3,520 m on Doorman Top. It represents the uppermost altitudinal limit for this species and for all ''Nepenthes''.<ref name=McPherson /> This material also consists of both male and female parts and is designated as ''Lam 1654''.<ref name=Danser /> Both of Lam's specimens represent greatly stunted, dwarf plants.<ref name=C&J /> They are deposited at Herbarium Bogoriense (BO), the [[herbarium]] of the [[Bogor Botanical Gardens]].<ref name=Danser /><ref name=monticola />
===Grouping with ''N. vieillardii''===
The first author to describe specimens of ''N. lamii'' was [[B. H. Danser]] in his seminal 1928 monograph, "[[The Nepenthaceae of the Netherlands Indies]]".<ref name=Danser /> Danser interpreted specimens of ''N. lamii'' as representing an outlying population of ''[[Nepenthes vieillardii|N. vieillardii]]'' (previously recorded only from [[New Caledonia]]) and used two specimens of ''N. lamii'' (''Pulle 843 bis'' and ''Lam 1654'') to illustrate the latter species (figure 26 in his monograph).<ref name=C&J /> In addition to the specimens mentioned above, Danser also listed ''Docters van Leeuwen 10834'' as New Guinean material of what he identified as ''N. vieillardii''.{{Ref_label|A|a|none}}
Danser explained his interpretation of ''N. vieillardii'' as follows:<ref name=Danser />
<blockquote>''N. Vieillardii'' has only been recorded from New Caledonia and the Isle of Pines up to the present, but the materials collected by the latter expeditions have shown, that at least in the western part of New Guinea it is not rare, in the latter country it varies more than in New Caledonia but it seemed impossible to me to distinguish separate species. Most alike the plants of New Caledonia are the number Pulle 834 and those of Docters van Leeuwen ; they only differ from the New Caledonia plants by the slightly developed indumentum, and the lid being more elliptical and bearing many glands on its lower surface. The plants of the Doormantop (Lam 1637 & 1654) have strongly abbreviate stems and are obviously an alpine form only ; they have nearly round lids like the plants of New Caledonia. The plants from the Ericatop are small and delicate in all parts ; they agree with the numbers first mentioned, by the elliptical and very glandular lids ; when the other New Guinea forms were not known, I would not have hesitated to distinguish those from the Ericatop specifically from those from New Caledonia. [...]
The habitat of this species in New Guinea are as well the virgin forest and the scrub as the treeless mountain tops. On the Doormantop, where Lam collected his plants, one would not expect ''Nepenthes'', the winds being there very strong and the temperature often very low, according to Lam often below the freezing point before sunrise. This hardiness gives ''N. Vieillardii'' a fair chance of dispersion.</blockquote>
For most of the remainder of the 20th century, authors followed Danser in treating ''N. lamii'' as a geographically isolated population of ''N. vieillardii''. A prominent example of this is [[Matthew Jebb]]'s 1991 monograph, "[[An account of Nepenthes in New Guinea|An account of ''Nepenthes'' in New Guinea]]",<ref name=Jebb /> where an illustration of ''N. lamii'' (figure 27) is labelled as showing ''N. vieillardii''.<ref name=C&J />
In 1994, [[Andreas Wistuba|A. Wistuba]], H. Rischer, B. Baumgartl, and B. Kistler observed wild plants of ''N. lamii'' (which they called ''[[Nepenthes vieillardii|N. vieillardii]]'') during a trip to Doorman Top in search of the enigmatic ''[[Nepenthes paniculata|N. paniculata]]''.<ref name=Wistuba>Wistuba, A. 1994. [http://www.omnisterra.com/botany/cp/list/cp94alld/2409.htm Re: ''Nepenthes''-discussion]. Carnivorous Plant Mailing List, September 15, 1994.</ref> The group were unsuccessful in rediscovering the latter species, but found ''[[Nepenthes maxima|N. maxima]]'' on the mountain.<ref name=Wistuba />
===Recognition as a distinct species===
''Nepenthes lamii'' was [[Species description|formally described]] by [[Matthew Jebb]] and [[Martin Cheek]] in their 1997 monograph, "[[A skeletal revision of Nepenthes (Nepenthaceae)|A skeletal revision of ''Nepenthes'' (Nepenthaceae)]]".<ref name=J&C /> The authors distinguished it from ''N. vieillardii'' on the basis of a number of [[#Related species|features of pitcher and indumentum morphology]]. They selected the [[holotype]] and [[holotype|isotype]] specimens from the ''Lam 1637'' series; both are deposited at Herbarium Bogoriense.<ref name=J&C /><ref name=C&J /><ref>Schlauer, J. N.d. [http://www.omnisterra.com/bot/cp_home.cgi?name=nepenthes+lamii ''Nepenthes lamii''] {{Webarchive|url=https://web.archive.org/web/20160303182025/http://www.omnisterra.com/bot/cp_home.cgi?name=nepenthes+lamii |date=2016-03-03 }}. Carnivorous Plant Database.</ref><ref>[http://ipni.org/ipni/idPlantNameSearch.do?id=995706-1 ''Nepenthes lamii'' M.Jebb & Cheek]. [[International Plant Names Index]] (IPNI).</ref> The [[type specimen]] is notable for exhibiting densely glandular [[tendril]]s.<ref name=C&J />
The next detailed treatments of ''N. lamii'' appeared in Cheek and Jebb's updated monograph of 2001, "[[Nepenthaceae (2001 monograph)|Nepenthaceae]]",<ref name=C&J /> and [[Stewart McPherson (geographer)|Stewart McPherson]]'s 2009 work, ''[[Pitcher Plants of the Old World]]'', which included colour habitat photographs of the species.<ref name=McPherson />
==Description==
''Nepenthes lamii'' reaches a maximum height of around 4 m, although plants growing towards the upper altitudinal limit of this species are greatly stunted [[shrub]]lets.<ref name=McPherson /> The [[Plant stem|stem]], which may be branched,<ref name=McPherson /> is rounded or angular in cross section and has [[plant stem|internode]]s up to 8 cm long.<ref name=C&J />

Leaves are thinly [[wikt:coriaceous|coriaceous]] and [[wikt:sessile|sessile]].<ref name=C&J /> The [[Leaf#Large-scale features (leaf morphology)|lamina]] (leaf blade) is most commonly linear, but may also be [[wikt:lanceolate|lanceolate]]. It reaches 22 cm in length by 5 cm in width. It has an acute to [[wikt:acuminate|acuminate]] apex and an obtuse base that may be [[wikt:decurrent|decurrent]] for more than 2 cm down the stem, although it is variable in this respect. Three to four longitudinal veins are typically present on either side of the [[midrib]], restricted to the distal quarter to third of the lamina, although they may number as many as 5 or as few as 0.<ref name=C&J /> [[wikt:pinnate|Pinnate]] veins, which may or may not be distinct, emerge obliquely from the midrib to form an irregular network in the distal half of the lamina.<ref name=C&J /> [[Tendril]]s may be densely glandular in some specimens.<ref name=C&J /> Laminae are typically green throughout, but may be tinged with purple, especially in stunted plants from higher elevations. The midrib and tendrils are often yellow and turn orange to red upon exposure to strong sunlight.<ref name=McPherson />
Rosette and lower pitchers are typically [[wikt:ovate|ovate]] in the basal half of the pitcher cup, becoming cylindrical and sometimes slightly [[wikt:infundibular|infundibular]] above. A conspicuous hip often delimits these two parts of the trap. Terrestrial pitchers may also be entirely ovate. They are relatively small, rarely exceeding 7 cm in height by 3 cm in width, although they occasionally reach 12 cm by 4 cm. A pair of wings (≤8 mm wide)<ref name=C&J /> runs down the [[ventral]] surface of the pitcher cup. The wings bear fringe elements up to 5 mm long. The pitcher mouth is [[wikt:suborbicular|suborbicular]] and has an oblique insertion.<ref name=C&J /> The [[peristome]] is cylindrical and becomes flattened and broader towards the sides and rear, measuring up to 7 mm in width. It bears ribs up to 0.5 mm high and spaced up to 0.8 mm apart. On the inner margin of the peristome, the ribs terminate in teeth up 1 mm long. The pitcher lid or [[operculum (botany)|operculum]] is [[wikt:orbicular|orbicular]]<ref name=C&J /> to elliptic<ref name=McPherson /> with a rounded apex and a rounded to [[wikt:cordate|cordate]] base.<ref name=C&J /> It bears no appendages, although the midline may be thickened into a 1 mm high ridge.<ref name=C&J /> It reaches 4.5 cm in length by 3.8 cm in width. The lower surface of the lid bears numerous [[nectar]] glands. Most are orbicular and measure 0.1–0.2 mm in diameter; this type occurs at a density of 1,500–2,000/cm<sup>2</sup>.<ref name=C&J /> Larger, longitudinally elliptic glands of 0.4 mm, and occasionally even up to 3 mm, are concentrated around the midline.<ref name=C&J /> An unbranched [[spur (botany)|spur]] measuring up to 5 mm in length is inserted near the base of the lid. It may or may not be flattened.<ref name=C&J /> Lower pitchers are typically reddish on their outer surface, often having speckles of a darker red colour. The inner surface varies from white to light orange. The peristome may be orange, through red, to purple. The lid is often yellowish on its lower surface and the same colour as the pitcher cup on its upper surface. Stunted plants from higher altitudes typically produce dark terrestrial pitchers.<ref name=McPherson />

Upper pitchers are infundibular and somewhat inflated in the basal quarter to third of the pitcher cup, becoming cylindrical or slightly infundibular above. A conspicuous hip often delimits these two parts of the trap. Rarely they may be wholly [[wikt:obovoid|obovoid]].<ref name=C&J /> Aerial traps are considerably larger than their terrestrial counterparts, growing to 18 cm in height by 5 cm in width. Ribs are present in place of wings. The peristome is cylindrical and up to 5 mm wide, being either uniformly broad throughout or slightly expanded at the sides and rear. Other parts are similar to those found in terrestrial traps. Aerial pitchers are usually yellowish throughout, occasionally with tinges of orange or red in older specimens. The ventral ridges are sometimes completely red. The inner surface may be white to cream coloured. The peristome ranges in colour from yellow to red, whereas the lid is most commonly yellow throughout.<ref name=McPherson />
''Nepenthes lamii'' has a [[raceme|racemose]] [[inflorescence]] up to 14 cm long. The [[peduncle (botany)|peduncle]] constitutes up to 7 cm of this length and has a basal width of around 2 mm. Flowers are borne solitarily on [[pedicel (botany)|pedicels]] (≤10 mm long) that lack [[bract]]s. [[Tepal]]s are elliptic and measure up to 3 mm in length by 3.3 mm in width.<ref name=C&J /> The [[wikt:androphore|androphore]] is up to 2.5 mm long and bears an [[anther]] head measuring up to 1.25 mm by 1.5 mm.<ref name=McPherson /><ref name=C&J />
Most parts of the plant lack a persistent [[indumentum]], being [[wikt:glabrous|glabrous]].<ref name=McPherson /> A very sparse covering of pale brown, woolly-[[wikt:scurfy|scurfy]] hairs measuring 0.2–0.4 mm is present on developing parts. The only mature parts that retain an indumentum are the inflorescence and tendrils, which bear an inconspicuously [[wikt:puberulent|puberulent]] covering of simple, black hairs of around 0.3 mm.<ref name=C&J />
==Ecology==
''Nepenthes lamii'' is [[endemism|endemic]] to the higher peaks of central [[Papua (province)|Papua]] province in [[West Papua (region)|West Papua]], [[New Guinea]],<ref name=McPherson /> including [[Doorman Top]] (also known simply as Mount Doorman) and [[Mount Erica]] of the [[Hellwig Mountains]].<ref name=C&J /> Sizable populations of this species have been found near [[Tembagapura]], a [[mining town]] situated at around 1,900 m in the [[Sudirman Range]].<ref name=McPherson /> ''Nepenthes lamii'' has an altitudinal distribution of 1,460–3,520 m [[above sea level]].<ref name=McPherson /><ref name=C&J /> The uppermost altitudinal limit of this species represents the highest known elevation of any ''Nepenthes'', although [[Nepenthes sp. Papua|''Nepenthes'' sp. Papua]] has been found at similar altitudes of around 3,500 m.<ref name=McPherson />
The species is highly variable in terms of growth habit and stature. At lower elevations, it is a scrambling climber that grows both terrestrially and [[epiphyte|epiphytically]] in a variety of habitats, including [[mossy forest]],<ref name=C&J /> recovering vegetation, open scrub, and stunted lower and upper [[montane forest]].<ref name=McPherson /> It is exposed to strong or direct sunlight at these sites.<ref name=McPherson /> Plants from higher altitudes become progressively more stunted and grow terrestrially among montane [[scrubland|scrub]] and [[grass]]es,<ref name=C&J /> montane [[Heath (habitat)|heath]], or in open sites with little other vegetation.<ref name=McPherson /> These dwarf ultrahighland specimens experience some of the lowest temperatures of any ''Nepenthes''; nighttime temperatures as low as 4 °C are not uncommon above 3,200 m<ref name=McPherson /> and on the upper slopes of Doorman Top they may fall below freezing.<ref name=Danser /> Plants growing in exposed sites on the mountain top also experience very strong winds.<ref name=Danser /> Although ''[[Nepenthes maxima|N. maxima]]'' has also been recorded from Doorman Top,<ref name=Wistuba /> no [[natural hybrid]]s involving ''N. lamii'' have been found to date.<ref name=McPherson />
The size and distribution of natural populations of ''N. lamii'' are incompletely known, making it difficult to assess the species' [[conservation status]].<ref name=McPherson /> However, the populations found near [[Tembagapura]] appear to be secure for the time being due to the tight controls on access and development present in the area.<ref name=McPherson /> The other known populations of ''N. lamii'' are all located in remote parts of Papua and many have not seen human contact in decades.<ref name=McPherson /> [[Stewart McPherson (geographer)|Stewart McPherson]] writes that ''N. lamii'' "may be anticipated from many of the high peaks of central Papua, and the species may accordingly have a wider distribution than is currently appreciated".<ref name=McPherson />

''Nepenthes lamii'' is quite morphologically distinct from all other ''Nepenthes'' of [[New Guinea]] and is thus easily identified in the wild.<ref name=McPherson /> Its pitchers are somewhat reminiscent of those of ''[[Nepenthes murudensis|N. murudensis]]'' and the giant form of ''[[Nepenthes tentaculata|N. tentaculata]]'', but both of these [[taxon|taxa]] are restricted to [[Borneo]].<ref name=McPherson /> Furthermore, although similar, the traps of ''N. lamii'' differ in that they have a round, as opposed to angular, pitcher mouth, and mature specimens never have filaments on the upper surface of the lid.<ref name=McPherson /> In addition, the lower pitchers are ovate to ovate-cylindrical in ''N. lamii'' and possess a wider peristome.<ref name=McPherson />
Although long confused with ''[[Nepenthes vieillardii|N. vieillardii]]'', ''N. lamii'' can be distinguished from that species on the basis of several stable differences. ''Nepenthes lamii'' almost completely lacks an [[indumentum]] on mature parts, whereas ''N. vieillardii'' bears a sparse to dense covering of white hairs measuring around 1 mm in length.<ref name=C&J /> In addition, the [[peristome]] ribs of ''N. lamii'' are usually more widely spaced at 0.3–0.4 mm apart versus 0.2–0.3 mm in ''N. vieillardii''.<ref name=C&J /> The density of nectar glands on the underside of the lid is also much higher in ''N. lamii'' (1,500–2,000 glands/cm<sup>2</sup> versus 75–100 glands/cm<sup>2</sup>).<ref name=C&J /><ref>Kurata, K., T.
