Nepenthes leonardoi is a Palawan mountain pitcher plant with a broad range of trap colours. Some dark specimens have become especially recognisable, but the species includes less dramatic colours and should not be identified from darkness alone.
Accepted identity
Kew accepts Nepenthes leonardoi S.McPherson, Bourke, Cervancia, Jaunzems & A.S.Rob., first published in Carniflora Australis in 2011. The recorded range is central Palawan. No synonyms or accepted infraspecific children are displayed in the reviewed record.
Pitchers and comparisons
In the first-hand expedition account, Stewart McPherson compares the plants with deaniana, gantungensis and mira, noting a broader, flatter peristome. Upper pitchers were abundant in the observed population, with examples reaching 26 centimetres. The species honours botanist Leonardo Co.
The original species account describes a continuous colour range from green to burgundy. Almost black upper pitchers occur in a minority of plants, with dark pigmentation and hairs contributing to their appearance, particularly when wet.
These observations explain why a photograph of one dark clone cannot represent every plant. For comparison, distinguish lower from upper pitchers, include the full rim and note whether the surface was wet. A black-looking image alone cannot separate pigment, surface texture and lighting.
Distribution and ecology
The original account records Schom-carp Peak and an easterly ridge in the Narra area, at 1,300–1,490 metres. It discusses possible further distribution, which should remain a hypothesis rather than be converted into a confirmed locality list.
The expedition report describes montane vegetation and difficult, densely vegetated ridge terrain. Its observations concern the plants encountered on that journey. A statement about their abundance along a route does not measure the total population or establish that all suitable mountains are occupied.
Growing guide
The mountain setting suggests a highland growing context, but the sources reviewed here do not establish a species-wide temperature optimum. The following is a practical assessment framework, with habitat inference kept separate from experimental cultivation evidence.
- Temperature: Obtain the propagator's successful daytime and overnight measurements. Compare both with your growing area, including its warm-season extremes.
- Establishment: Record whether the plant is recently rooted, recently acclimatised or already established. Its immediate transition needs cannot be read from a species name alone.
- Air and moisture: Monitor the actual leaf and pot environment. A humid mountain description is not a prescription for continuously wet foliage in an enclosed space.
- Light: Adjust exposure gradually and assess new growth. Avoid chasing a particular dark colour at the expense of overall plant condition.
- Support: Retain space and a support plan for climbing growth, while recording the transition to upper pitchers.
Clones and provenance
A named nursery clone, supplier code or dark-selection label is a separate piece of information from the botanical species name. Preserve it exactly when dividing or taking cuttings. Seedlings from the same parents should keep their batch identity without being represented as copies of one selected parent.
For an uncertain plant, keep the original label, the source's explanation and dated photographs together. Additional mature characters may support a later determination, but an attractive photograph from another collection cannot fill a gap in provenance.
Editorial record: Reviewed 2 October 2026. Accepted name, original range account and first-hand expedition observations checked. Cultivation limits remain untested by these sources. Verified photographs, owner and visual review remain pending.
