| Nepenthes × harryana Burb. (1882) |
Nepenthes × harryana (pronounced /nəˈpɛnθiːz hæɹiːjɑːnə/, after Harry Veitch, last member of the well known horticultural firm of Veitch & Sons) is the natural hybrid between N. edwardsiana and N. villosa. 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.
It was originally described as a species in 1882 by Frederick William Burbidge.[1] John Muirhead Macfarlane was the first to realise its hybrid origin and described it as such in his monograph of 1908.[2] Danser wrote that N. × harryana could be a hybrid as Macfarlane suggested, or a form of N. villosa together with N. edwardsiana.[3]
N. × harryana can be distinguished from N. villosa on the basis of its pitcher morphology. The pitchers of the hybrid are more cylindrical than those of N. villosa, whereas the indumentum is more dense than that of N. edwardsiana. The hip of the pitcher cup, which is found just below the peristome in N. villosa and in the lower quarter of N. edwardsiana pitchers, is located around the middle of N. × harryana pitchers. However, N. villosa plants from Mount Tambuyukon are easier to confuse with this hybrid, as they produce pitchers that may be elongated slightly above the hip.[4]
N. × harryana is known from a ridge above the Upper Kolopis River and from two locations along the Kinabalu summit trail. Since N edwardsiana does not grow along the summit trail, it cannot be confused with this hybrid there.[4] Burbidge wrote that N. edwardsiana, N. × harryana, and N. villosa "are quite distinct in zone of the mountain".[1]
