Nepenthes jacquelinae (West Sumatra)

Nepenthes jacquelinae

Very nice spotted pitcher of N. jacquelinae.

Nepenthes jacquelineae has to be one of the most beautiful and unique species of nepenthes on account of its squat, robust pitchers that have one of the most spectacular and distinctive peristomes of the genus.
Endemic to the Barisan Mountains of West Sumatra, N. jacquilineae grows primarily as an epiphyte, but also occasionally terrestrially, in high altitude (1700-2200m) dense most forest. These forests are almost constantly enveloped in fog and experience daily rainfall, remaining cool and moist. It is a true highland plant. It is otherwise a relatively hardy and easy grower, provided the correct climate is provided.

N. jacquelineae produces relatively small (= 6cm) lower pitchers. These are squat, funnel-shaped (infundibular), rounding towards the top, and possess a wide, flattened peristome (upto 1cm wide), that resembles a pair of flattened lipsticked lips. Upper pitchers are produced on vines up to 5m in length, and are much larger than their lower counterparts. They are robust and squat, being up to 15cm high and 10cm wide, lacking any wings that may have been present in the lowers. The most characteristic feature of N. jacquelineae however is its greatly expanded peristome, which can be up to 3.5 cm wide in upper pitchers. It is unusually smooth. While pitchers are reminiscent of a robust form of the related N. jamban but with a greatly expanded peristome, only the unrelated N. platychila (Borneo) produces a similar peristome structure. While N. platychila may have the stripes, N. jacquelineae definitely wins any competitions for colour. Pitchers range in colour from green, through yellow and oranges, to fully red, and may be lightly speckled. Peristomes are usually an orange to deep red colour. While a green pitcher, with red peristome is most common, exceptional individuals can even produce dark fully maroon-purple pitchers. The flared horizontal disk-like peristomes characteristic of this species may act as a landing platform for flying insects, the primary prey caught by the upper pitchers. Especially viscous, syrupy pitcher fluid similar to that found in N. inermis and a few other Sumatran species, coats the pitcher walls. This is hypothesized to enable pitchers to function as flypaper traps as well as typical pitfall traps.
The species was discovered by Charles Clarke and Troy Davis. The name ëjacquelineaeí is in honour of Charles Clarke's wife, Jacqueline Clarke, while N. izumeae (discovered on the same trip) is named after of Izumi Davis, Troyís wife.


Cultivation Guidelines:
Light: Bright indirect or dappled light. Naturally grows in relatively low light, as sunlight is diffused by fog and forest.
Temperature: True highland conditions. Requires cool night time temperatures, and moderate daytime temperatures.
Growing medium: An open, mossy but well-draining mix. A mix of high quality sphagnum moss with horticultural-grade perlite, a bit of good quality peat-moss and pine bark works well. The proportion of Sphagnum in the mix should ideally be quite high.
Extra notes on Cultivation: Endemic to forests almost constantly enveloped in fog, this species appreciates cool, moist conditions and very high humidity.
