All three specimens were collected from Popokvil falls, Mount Bokor, and are deposited at the Museum National d'Histoire Naturelle in Paris.

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.

[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] 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.

It bears up to 80 flowers borne on one-flowered pedicels (≤9 mm long), or rarely two-flowered partial peduncles.

[1] All vegetative and floral parts of N. bokorensis bear an indumentum of silvery or brownish hairs up to 1 mm long.

[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.

[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.

[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] 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] The ant-trapping habit of N. bokorensis is reflected in the local Khmer name for the plant, ampuong sramoch, which means "ants' pithole".

[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] 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.

[21] Nepenthes bokorensis is most closely allied to several other Indochinese pitcher plants, particularly N. kampotiana, N. smilesii, and N. thorelii.

[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.

[23] N. thorelii Lecomte simile, sed foliis longioris latioris oblongis sessilibus vel subpetiolatis basaliter amplexicaulibus peristomio robusto cylindrico pedicellis interdum 2-floribus differt.
