Front cover (left) and two representative figures from Macfarlane's monograph. The one in the centre shows vegetative and floral parts of N. ampullaria; the one on the right illustrates various glandular structures.
The following 58 taxa are enumerated and detailed in Macfarlane's "Nepenthaceae". Varieties recognised by Macfarlane are also included. Taxon names are listed as they appear in the monograph, including orthographic variants, though specific epithets derived from proper nouns have been decapitalised.
In addition, Macfarlane lists N. gracillima as a possible synonym of N. albomarginata; the species are numbered 7* and 7, respectively.[1]
Reviews and later works
At the time of its publication, "Nepenthaceae" was praised for its many high quality illustrations (95 images in 19 figures) of both morphological and anatomical features.[11]
Research conducted after World War I quickly rendered Macfarlane's monograph outdated.[2] Much additional herbarium material was accumulated during this time, representing both new species and better specimens of known taxa, which highlighted issues with previous interpretations.[4][9] The need for a new revision of the genus was satisfied with the publication of B. H. Danser's seminal 1928 monograph, "The Nepenthaceae of the Netherlands Indies". However, Danser's treatment did not encompass the entire range of the genus. It would not be until Matthew Jebb and Martin Cheek's 1997 monograph, "A skeletal revision of Nepenthes (Nepenthaceae)", that the entire genus was once again revised in a single work.[9]
