"Nepenthaceae" is a monograph by Joseph Dalton Hooker on the tropical pitcher plants of the genus Nepenthes.
[1] Published only a year after Ernst Wunschmann's "Über die Gattung Nepenthes", Hooker's monograph expanded the number of known species considerably.
[2] Hooker recognised 33 species, including 7 described for the first time: N. bicalcarata, N. celebica (later synonymised with N. maxima),[2] N. echinostoma (later reduced to a variety of N. mirabilis),[2] N. hirsuta, N. khasiana, N. tentaculata, and N. vieillardii.
[5] The manuscript of Hooker's monograph formed the basis for an article by Maxwell T. Masters published in the April 20, 1872 issue of The Gardeners' Chronicle and Agricultural Gazette.
[1] This classification would be expanded upon in the 1895 monograph of Günther Beck von Mannagetta und Lerchenau, "Die Gattung Nepenthes",[7] and the 1936 work of Hermann Harms, "Nepenthaceae".
