''Nepenthes × harryana'' (; after Harry Veitch, head of the well known horticultural firm of Veitch & Sons) is the natural hybrid between ''N. edwardsiana'' and ''N. villosa''.〔McPherson, S.R. & A. Robinson 2012. ''Field Guide to the Pitcher Plants of Borneo''. Redfern Natural History Productions, Poole.〕 Its two parent species are very closely related and so ''N. × harryana'', which is intermediate in form, may be difficult to distinguish from either of them. ==Botanical history== ''Nepenthes × harryana'' was first described by Frederick William Burbidge in 1882. Burbidge wrote of it as follows:〔
Apart from these I found an intermediate between N. villosa and N. Edwardsiana, also epiphytic on Casuarina. This is, I believe, unnamed ; if so, I should like it to be called Nepenthes Harryana. Now, if a dried pitcher of N. Edwardsiana be examined, the upper four-fifths of it will be seen to be membranous, the lower part leathery and hard ; in N. villosa nearly all is hard and leathery except about half-an-inch below the hardened rim of the urns ; in N. Harryana about one-third is hard, and two-thirds soft or membranous below the rim. The edge of the pitcher mouths in these three kinds is quite distinct from those of all others, as shown in my sketches.
()
Sir Joseph Hooker, in ''Linn. Trans.'', vol. xxii., suggested that N. villosa and N. Edwardsiana might be forms of the same species. This is not so, however, they are quite distinct in zone on the mountain, and in habit of growth also, and in colour. Then N. Harryana is a hybrid no doubt, which shows they have distinct sexual characters.
John Muirhead Macfarlane agreed with Burbidge's hybrid hypothesis and described the plant as such in his monograph of 1908, "Nepenthaceae".〔Macfarlane, J.M. 1908. Nepenthaceae. In: A. Engler ''Das Pflanzenreich IV'', 111, Heft 36: 1–91.〕 B. H. Danser, in his 1928 revision, wrote that ''N. × harryana'' could be a hybrid as Macfarlane suggested or a form of ''N. villosa'' together with ''N. edwardsiana''. Favouring the latter interpretation, he synonymised both taxa with ''N. villosa''.〔Danser, B.H. 1928. The Nepenthaceae of the Netherlands Indies. ''Bulletin du Jardin Botanique de Buitenzorg'', Série III, 9(3–4): 249–438.〕
