維奇豬籠草(學名:Nepenthes veitchii)是婆羅洲特有的熱帶食蟲植物。[3]其廣泛分布於婆羅洲西北部。其種加詞「veitchii」來源於維奇苗圃的主人,詹姆斯·維奇。[4]
低地地區的樹林中維奇豬籠草常附生,其以葉柄環抱樹杆向上生長。而在高地地區泥炭沼澤的維奇豬籠草則多陸生。[3]巴里奧地區的維奇豬籠草似乎嚴格陸生,未在該地區觀察到其附生植株。此外,低地地區和高地地區的維奇豬籠草在形態上也有區別,低地變型比高地變型的唇窄。[3]
維奇豬籠草被認為產於菲律賓的羅伯坎特利豬籠草(N. robcantleyi)之間存在著密切的近緣關係。[5]其也與寶特瓶豬籠草(N. truncata)進行了比較。[6]

植物學史
弗雷德里克·威廉·伯比奇在《園丁紀事》中描述了維奇豬籠草的生活習性:[注 1][7][8]
“ | 維奇豬籠草,嚴格附生。除了在高20至100英尺的樹幹上,我從未在任何地方上看到過維奇豬籠草。其葉片對生,部分葉片環扣著樹幹,就像一個人環抱住樹幹一樣。據我所知沒有其他任何豬籠草具有這樣的生活習性。 | ” |
1865年,奧多阿多·貝卡利在山都望山山頂發現了維奇豬籠草。他對其發現敘述到:[注 2][7][9]
“ | 這種豬籠草極為精緻,罕見……部分標本可長達10英尺。該物種捕蟲籠的籠口為黃色、垂直,特別突出顯眼。其鮮艷的色彩可吸引昆蟲進入其完美的捕蟲籠中。 | ” |

注釋
- 弗雷德里克·威廉·伯比奇在《園丁紀事》中描述維奇豬籠草生活習性的原文:[7][8]
“ Now as to N. Veitchii. This is a true epiphyte. I never met with it on the ground anywhere, but in great quantity 20—100 feet high on tree trunks. Its distichous habit is unique, I fancy, and then some of the leaves actually clasp around the tree just as a man would fold his arms around it in similar circumstances. No other species of Nepenthes, so far as I know, has this habit. ” - 奧多阿多·貝卡利對在山都望山發現的維奇豬籠草的敘述原文:[7][9]
“ This is one of the finest and rarest of all pitcher-plants. [...] Some of the specimens I got measured quite ten inches in length. The mouth of the pitcher in this species is certainly its most conspicuous and remarkable part by reason of its rich orange colour and its vertical position. It is also a perfect trap to entice insects into its interior, attracting them from a distance by its bright colours. Sir Joseph Hooker compares the mouth of the pitchers of N. veitchii to the gills of a fish, to which, indeed, with their narrow lamellae converging to the centre, they bear considerable resemblance. ”
