Nepenthaceae (2001 monograph)

"Nepenthaceae" is a monograph by Martin Cheek and Matthew Jebb on the tropical pitcher plants of Malesia, which encompasses Brunei, Indonesia, Malaysia, Papua New Guinea, the Philippines, and Singapore. It was published in 2001 by the National Herbarium of the Netherlands as the fifteenth volume of the Flora Malesiana series. The species descriptions presented in the monograph are based on the authors' field observations in Borneo, New Guinea, and Peninsular Malaysia, as well as the examination of plant material deposited at 20 herbaria.

Cheek and Jebb recognised 83 species from Malesia, including three nothospecies (N. × hookeriana, N. × kinabaluensis, and N. × trichocarpa) and one "little known species" (N. deaniana). In addition, they mentioned four "excluded species": N. cincta (likely a natural hybrid between N. albomarginata and N. northiana), N. cristata ("a nonsense species based on mixed types"), N. lindleyana (of which the original material could not be located), and N. neglecta (which the authors considered likely to represent N. gracilis).
