morphologically distinct from all other Nepenthes of New Guinea and is thus easily identified in the wild. Its pitchers are somewhat reminiscent of those of N. murudensis and the giant form of N. tentaculata, but both of these taxa are restricted to Borneo. 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. In addition, the lower pitchers are ovate to ovate-cylindrical in N. lamii and possess a wider peristome. Although long confused with 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. 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. The density of nectar glands on the underside of the lid is also much higher in N. lamii (1500–2000 glands/cm2 versus 75–100 glands/cm2).

It includes male floral material and is held at Herbarium Bogoriense (BO). References Further reading Bauer, U., C.J. Clemente, T. Renner & W. Federle 2012.
