Nepenthes of Borneo is a monograph by Charles Clarke on the tropical pitcher plants of Borneo. It was first published in 1997 by Natural History Publications (Borneo), and reprinted in 2006. Clarke describes it as "primarily an ecological monograph".
The book describes and illustrates 31 species in detail. A further two "undescribed and incompletely diagnosed taxa" are included: Nepenthes sp. A (possibly a form of N. fusca) and Nepenthes sp. B (later described as N. hurrelliana). Six taxa are also covered under "dubious species and erroneous records": N. alata, N. gymnamphora, N. macfarlanei, and N. maxima (which are all shown to be absent from the island); N. sp. "elegance" (which is recognised as a variety of N. rafflesiana, was later described by Clarke and colleagues as N. baramensis, and is now recognised as N. hemsleyana); and N. neglecta (which Clarke suggests is a natural hybrid between N. gracilis and N. mirabilis). The monograph also provides brief descriptions of 16 selected natural hybrids.
The taxonomy presented in Nepenthes of Borneo almost wholly agrees with that of Matthew Jebb and Martin Cheek's 1997 monograph, "A skeletal revision of Nepenthes (Nepenthaceae)". Clarke makes only two major revisions: restoring N. faizaliana as a distinct species and sinking N. borneensis in synonymy with N. boschiana.
