Борнеоның құмыра гүлі: Nepenthes hurrelliana (Nepenthes mollis синонимі)

a dated classification of this taxonSpecies of pitcher plant from Borneo

Nepenthes hurrelliana /n//ᵻ/'/p//ɛ//n//θ//iː//z// //h//ʌ/,/r//ɛ//l//i/'/ɑː//n//ə/ (synonymous with Nepenthes mollis) is a tropical pitcher plant endemic to Borneo, where it has been recorded from northern Sarawak, southwestern Sabah, and Brunei. It is of putative hybrid origin; its two original parent species are thought to be N. fusca and N. veitchii. A thick indumentum of rusty brown hairs covers the entire plant, a characteristic presumably inherited from the latter.

Nepenthes hurrelliana was known to botanists for some time prior to its description, although authors differed as to its identity, with most treating it as either a form of N. veitchii, a form of N. maxima, or a natural hybrid. which likely represents this species. In 1999, Bruce Salmon proposed that this taxon might be conspecific with the enigmatic N. mollis, of which only a single pitcherless specimen is known. Nepenthes hurrelliana is named after Andrew Hurrell, who studied the plant on Mount Murud in 1995 and whose field observations showed that it grew in self sustaining populations independent of its putative parent species and could thus be considered a distinct species.

Nepenthes hurrelliana is a climbing plant. Forms from different localities vary slightly in morphology. Plants from Mount Mulu and several other mountains have internodes up to 10 cm long. Specifically, it has been found on Mount Lumarku, Mount Mulu, Mount Murud, and mountains of the Meligan Range near Long Pasia (including Mount Rimau). This would support the status of N. hurrelliana as a species since populations of this taxon appear to be stabilised and it is abundant where it does grow.

The lower pitchers of N. hurrelliana are distinctive, but the upper ones bear a close resemblance to those of N. fusca. Of the Bornean pitcher plant flora, only these two species have such a narrowly triangular lid. The upper pitchers of N. hurrelliana differ in having a horizontal mouth that rises abruptly into a long neck at the back and in having a hirsute basal crest on the underside of the lid. and N. veitchii.

As of 2019, Nepenthes hurrelliana has been shown to be a heterotypic synonym of Nepenthes mollis through a study by Alastair Robinson et al., titled "Revisions in Nepenthes following explorations of the Kemul Massif and the surrounding region in north central Kalimantan, Borneo". The study also discovered a new species in the genus on the island.
