维奇猪笼草(学名:Nepenthes veitchii)是婆罗洲特有的热带食虫植物。[3]其广泛分布于婆罗洲西北部。其种加词“veitchii”来源于维奇苗圃的主人,詹姆斯·维奇。[4]
低地地区的树林中维奇猪笼草常附生,其以叶柄环抱树杆向上生长。而在高地地区泥炭沼泽的维奇猪笼草则多陆生。[3]巴里奥地区的维奇猪笼草似乎严格陆生,未在该地区观察到其附生植株。此外,低地地区和高地地区的维奇猪笼草在形态上也有区别,低地变型比高地变型的唇窄。[3]
维奇猪笼草被认为产于菲律宾的罗伯坎特利猪笼草(N. robcantleyi)之间存在着密切的近缘关系。[5]其也与宝特瓶猪笼草(N. truncata)进行了比较。[6]

植物学史
弗雷德里克·威廉·伯比奇在《园丁纪事》中描述了维奇猪笼草的生活习性:[注 1][7][8]
“ | 维奇猪笼草,严格附生。除了在高20至100英尺的树干上,我从未在任何地方上看到过维奇猪笼草。其叶片对生,部分叶片环扣着树干,就像一个人环抱住树干一样。据我所知没有其他任何猪笼草具有这样的生活习性。 | ” |
1865年,奥多阿多·贝卡利在山都望山山顶发现了维奇猪笼草。他对其发现叙述到:[注 2][7][9]
“ | 这种猪笼草极为精致,罕见……部分标本可长达10英尺。该物种捕虫笼的笼口为黄色、垂直,特别突出显眼。其鲜艳的色彩可吸引昆虫进入其完美的捕虫笼中。 | ” |

- 弗雷德里克·威廉·伯比奇在《园丁纪事》中描述维奇猪笼草生活习性的原文:[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. ” - 奥多阿多·贝卡利对在山都望山发现的维奇猪笼草的叙述原文:[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. ”
