A skeletal revision of Nepenthes (Nepenthaceae)

[2] Jebb and Cheek's revision was based on "collaborative work by both authors since 1984, largely on herbarium specimens, but including fieldwork in New Guinea, Indonesia, Malaysia, Singapore and Madagascar".

This included the recognition of N. eustachya, N. hispida, N. ramispina, and N. sumatrana as distinct species, whereas previously they had been treated as heterotypic synonyms of N. alata, N. hirsuta, N. gracillima, and N. treubiana, respectively.

Unlike the latter work, however, it was primarily an ecological monograph and did not attempt to provide an alternative taxonomic interpretation of the Bornean taxa (with the exception of treating N. borneensis in synonymy with N. boschiana and retaining N. faizaliana as a distinct species).

[6] However, several of the taxonomic revisions made by Jebb and Cheek were reversed in Clarke's subsequent monograph, Nepenthes of Sumatra and Peninsular Malaysia, published in 2001.

However, several debatable points have to be clarified previous to the completion of the Flora Malesiana account.Schlauer disagreed with Jebb and Cheek's synonymisation of N. talangensis with N. bongso and their interpretation of N. stenophylla, which, according to Schlauer, served to perpetuate "Danser's misconception".
