"Nepenthaceae" is a monograph by John Muirhead Macfarlane on the tropical pitcher plants of the genus Nepenthes. It was published in 1908 in Adolf Engler's Das Pflanzenreich. It was the most exhaustive revision of the genus up to that point, covering all known species, and included detailed accounts of the structure, anatomy, and development of Nepenthes.
