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. [...] <p> 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. 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", where an illustration of N. lamii (figure 27) is labelled as showing N. vieillardii. In 1994, A. Wistuba, H. Rischer, B. Baumgartl, and B. Kistler observed wild plants of N. lamii (which they called N. vieillardii) during a trip to Doorman Top in search of the enigmatic N. paniculata. The group were unsuccessful in rediscovering the latter species, but found N. maxima on the mountain. Recognition as a distinct species Nepenthes lamii was formally described by Matthew Jebb and Martin Cheek in their 1997 monograph, "A skeletal revision of Nepenthes (Nepenthaceae)". The authors distinguished it from N. vieillardii on the basis of a number of features of pitcher and indumentum morphology. They selected the holotype and isotype specimens from the Lam 1637 series; both are deposited at Herbarium Bogoriense. The type specimen is notable for exhibiting densely glandular tendrils. The next detailed treatments of N. lamii appeared in Cheek and Jebb's updated monograph of 2001, "Nepenthaceae", and Stewart McPherson's 2009 work, Pitcher Plants of the Old World, which included
