Nepenthes kampalili is a recently described Mindanao species associated with high-elevation bonsai forest. Its hairy ground pitchers and the way its tendrils meet the leaves are more informative than a general resemblance to other stout Philippine pitcher plants. The published account also contains important limits: upper pitchers were not observed at the type locality.
Accepted name
Plants of the World Online accepts Nepenthes kampalili Lagunday & Amoroso, published in Phytotaxa in 2024. Kew records the Philippines as its native range. No synonyms or accepted infraspecific children are displayed in the reviewed record.
The source for the detailed account below is the published taxonomic treatment by Lagunday, Yorong and Amoroso. Authorship of a paper and authorship of a botanical name are different records: the name is attributed to Lagunday and Amoroso.
Identification
The diagnosis distinguishes it from N. peltata through an apical, rather than peltate, tendril attachment and densely hairy ground pitchers and upper lid surfaces. The authors also report occasional paired spurs. Ground pitchers are egg-shaped to urn-shaped, with colours ranging from olive green to red. Upper pitchers were not observed at the type locality.
“Apical” means that the tendril continues from the leaf tip. “Peltate” describes an attachment on the blade surface inward from its end. A clear photograph of this junction is therefore more useful than a photograph that crops off the leaf.
Absence of an observed upper pitcher is an evidence limit. It does not demonstrate that the species can never produce one. A purported upper pitcher needs an authenticated connection to the plant and careful comparison; it should not be filled in from a related species.
Habitat and conservation
The treatment places the species on Mount Kampalili in Davao de Oro, Mindanao, at 2,200–2,320 metres. Its habitat account describes limestone karst bonsai forest, with plants in moss and crevices. The authors estimated about 200 mature individuals at one known site and proposed Critically Endangered under criterion B1ab(i). This is their 2024 assessment, not a newly verified IUCN listing.
The paper's broader text also mentions ultramafic habitat, so its substrate terminology should be checked before any precise chemical cultivation inference. This profile follows the species habitat paragraph when reporting the limestone setting and preserves that textual uncertainty.
Growing guide and evidence boundaries
The elevation suggests a cool mountain context, but the description does not establish a successful nursery temperature schedule. A species this recently described should not acquire an exact care recipe simply because one can be copied from another highland Nepenthes.
- Before acquisition: Ask for propagated provenance and records of successful cultivation of the actual accession. A species name on a sales label is not evidence of acclimatisation.
- Temperature planning: Evaluate whether the growing space can maintain stable mountain conditions through the warmest season. Record daytime and overnight measurements close to the plant.
- Substrate: Do not add lime solely because the habitat is described as limestone. Bedrock, moss and the chemistry around roots are separate questions.
- Observation: Record the newest leaf, tendril attachment, hairs and successive ground pitchers. Keep scale and developmental stage in the photographs.
- Propagation: Preserve accession identity when making divisions or cuttings. No species-specific rooting success rate or seed protocol is established by the taxonomic treatment reviewed here.
What a useful collection record should contain
Separate known facts from proposed explanations. For example, a dated photograph can establish that a cultivated plant produced a certain pitcher; it does not establish that all wild plants have that feature. Record the observer, accession and conditions with any unusual growth.
A small published population estimate should prompt careful sourcing, not an assumption that every commercial plant came from that population. Keep supplier evidence and botanical evidence together without treating either as a substitute for the other.
Editorial record: Reviewed 2 October 2026. Original treatment and Kew acceptance checked; substrate wording uncertainty and unobserved upper pitchers retained. Verified photography, owner and visual review remain pending.
