Die Gattung Nepenthes

"Die Gattung Nepenthes: Eine monographische Skizze" (lit. "The genus Nepenthes: A monographic sketch") is a German-language monograph by Günther Beck von Mannagetta und Lerchenau on the tropical pitcher plants of the genus Nepenthes. It was published in 1895 in four parts, spread over the March, April, May and June issues of Wiener Illustrirte Garten-Zeitung.

Beck recognised and enumerated 67 major taxa, almost half of which were hybrids. Additionally, seven taxa and unnamed horticultural hybrids are listed at the end of the work under "Ungenügend bekannte Arten, Mischarten" (insufficiently known species, mixed species).

Beck described four new species: N. fallax (later synonymised with N. stenophylla, although this is disputed),N. hispida, N. smithii (later synonymised with N. distillatoria), and N. spuria (later synonymised with N. northiana). Beck was also the first to publish N. sumatrana under its present binomial combination, although he introduced it under the entry for N. maxima with the words "Hierzu gehört als Varietät: N. sumatrana" (this includes a variety: N. sumatrana).

Beck also introduced a number of new varieties. These included the species varieties N. albomarginata var. tomentella, N. albomarginata var. typica, N. gracilis var. longinodis, N. gracilis var. teysmanniana, N. rafflesiana var. ambigua, N. rafflesiana var. excelsior (later synonym of N. × hookeriana), and N. rafflesiana var. typica, as well as the hybrid variety N. hybrida var. typica (N. gracilis × N. khasiana).
