Nepenthes of Sumatra and Peninsular Malaysia is a monograph by Charles Clarke on the tropical pitcher plants of Sumatra, Peninsular Malaysia, and their minor surrounding islands. It was published in 2001 by Natural History Publications (Borneo). Clarke described it as "intermediate between an ecological monograph and a taxonomic one".
The work was conceived in late 1997 and represents the culmination of 3 years of intensive research that included 15 field trips and numerous herbarium visits. The project encountered a number of difficulties and setbacks, including a "severe drought" in 1997 and political unrest in the following two years. Of the species covered in the book, Clarke observed all but three in the field.Nepenthes lavicola could not be reached due to the prevailing political situation in parts of Aceh, whereas N. tenuis had not been relocated in the wild at the time. What Clarke called N. gracillima was also not seen by him in the field; this taxon is now known as N. alba.
The book describes and illustrates 34 species in detail. A further two "undescribed and incompletely diagnosed taxa" are included: Nepenthes species A (later described as N. rigidifolia) and Nepenthes species B (later described as N. izumiae). Three "little known taxa" are also covered: N. alata (which is shown to be absent from the region), N. beccariana, and N. junghuhnii. The monograph also provides brief descriptions of 18 selected natural hybrids.
Clarke reversed several of the taxonomic revisions made by Matthew Jebb and Martin Cheek in their 1997 monograph, "A skeletal revision of Nepenthes (Nepenthaceae)". Nepenthes longifolia, N. talangensis, and N. tenuis were restored to species status, while N. pectinata was reduced to a heterotypic synonym of N. gymnamphora. Nepenthes jacquelineae, named after Clarke's wife, was described as a new species. Clarke also interpreted N. pyriformis (formally described in 2001) as a natural hybrid between N. inermis and N. talangensis.
