Nepenthes hurrelliana is a hairy Bornean mountain pitcher plant with a prominent hooked structure beneath the pitcher lid. It also has an important naming problem: the name remains accepted in the Kew treatment used for this series, while a later field-based revision places it under N. mollis. Readers may encounter both names for related collection material.
Two published taxonomic treatments
Kew’s current individual record accepts Nepenthes hurrelliana Cheek & A.Lamb, published in 2003, and gives Sabah and Brunei in its native-range summary. It displays no synonyms or accepted infraspecific children. This profile retains the name because it is part of the series' dated baseline.
Robinson and colleagues’ 2019 revision instead treats hurrelliana as a heterotypic synonym of N. mollis, following examination of the latter's type population in the Kemul Massif. “Heterotypic” means the names were based on different type specimens; the authors concluded that they represent one species. The disagreement is recorded here rather than silently choosing one label for all cultivated accessions.
Keep the original acquisition name, the current determination and the source of a name change in separate fields. A new determination should improve the record without erasing its history. When comparing photographs or growing reports, establish which taxonomic treatment the author followed.
Features in the original description
The 2003 description by Cheek and colleagues describes an epiphytic or terrestrial climber with dense rusty hairs on stems, leaf stalks and tendrils. Intermediate pitchers widen upwards and develop a high rear column; upper pitchers are more funnel-shaped. The lid carries a strongly hooked basal appendage. Bracts on male flower branches helped distinguish it from the proposed parental species in earlier hybrid interpretations.
The original treatment records summit ridges at 1,620–2,100 metres and includes Sabah, Sarawak and Brunei. It assessed the species as Vulnerable under the criteria then used. Those historical records should retain their date and taxonomic scope. They do not automatically override either a later distribution summary or a later conservation assessment.
What an identification photograph needs
Photograph the underside of the lid without cutting off its base. That is where the hooked appendage must be evaluated. A view directly into the pitcher may conceal it, while a side view can show both the hook and the raised rear of the mouth.
Include the stem and leaf stalk in the image set so that the hair covering is documented on identifiable structures. Record whether the pitcher came from a rosette, a transitional shoot or a climbing stem. A comparison based on different growth stages can obscure similarities as easily as it can invent differences.
The historical suggestion of hybrid origin is not a verified pedigree for a nursery plant. Do not replace a species label with a cross formula solely because an older book suggested that explanation. Equally, a modern hybrid containing this ancestry should retain its complete documented parentage.
Growing context
Cooler mountain conditions are a reasonable inference from the cited ridge records, but those records do not establish precise temperature limits for every accession sold under either name. Ask the supplier which name concept and source population their record uses, as well as how the plant was propagated and established.
The NECPS general guide supports humidity, air circulation and a well-drained root environment, with cooler conditions for highland plants. These principles are background guidance, not a species-specific trial.
Compare measured day and night conditions in the proposed growing space with the supplier's experience. Keep environmental changes beside dated observations of leaves and pitchers. A growing record attached only to a disputed name, with no accession or conditions, is difficult to interpret or repeat.
Propagation and review
No reliable species-specific rooting duration or maximum cultivated size is established here. Preserve accession numbers when propagating vegetatively and retain documented parents for seed. Name uncertainty should travel with propagated material until it is resolved.
Editorial record: Reviewed 2 October 2026. Kew acceptance, the 2003 original description and the 2019 synonymy are explicitly distinguished. Photography, owner and visual review remain pending.
