Distribution of N. mirabilis.
Synonyms

Nepenthes mirabilis (pron.: /nɨˈpɛnθz mɪˈræbɨlɪs/; from Latin: mirabilis = wonderful), or the Common Swamp Pitcher-Plant,[4] is a tropical carnivorous plant species of the pitfall trap variety. It has by far the widest distribution of any Nepenthes species and is known from the following countries and regions: Australia (Cape York Peninsula), Borneo, Cambodia, Caroline Islands (Palau and Yap), China (Guangdong Province, Hainan,[5][6]Hong Kong, and Macau), D'Entrecasteaux Islands, Java, Laos, Louisiade Archipelago, Maluku Islands, Myanmar, New Guinea, Peninsular Malaysia, Philippines (Dinagat and Mindanao), Sulawesi, Sumatra, Thailand, and Vietnam.[7][8][9][10][11][12][13][14]

The species exhibits great variabiliy throughout its range. One of the more notable varieties, N. mirabilis var. echinostoma, is endemic to Brunei and Sarawak and possesses an extremely wide peristome.[15]

The conservation status of N. mirabilis is listed as Least Concern on the 2006 IUCN Red List of Threatened Species.[16] In Hong Kong, it is a protected species under Forestry Regulations Cap. 96A.

According to Matthew Jebb and Martin Cheek, the pitchers of N. mirabilis are used as toy phallocrypts in New Guinea.

Taxonomy

Nepenthes mirabilis is closely related to N. rowanae and N. tenax, the only two Nepenthes species endemic to Australia.

Differences between N. mirabilis and N. rowanae (Clarke & Kruger, 2005)
Character N. mirabilis N. rowanae
Morphology of leaf blade Acute to rounded Contracted towards the apex, then continuing along the tendril as a narrow, acute, extension
Insertion of tendril to leaf blade Simple Peltate
Pitcher wings Simple, bearing multicellular fringe elements Often flattened at front, forming a T-shape in XS, multicellular fringe elements often present
Leaf blade texture Usually chartaceous Strongly coriaceous
Leaf blade attachment to stem Simple, or rarely decurrent for ⅓ the length of the internode Decurrent for at least ½ the length of the internode, usually more
Gland density in lower portion of pitcher 1600-2500 / cm² Approximately 3600 / cm²
Position of pitcher hip in upper pitchers Mid-way, to lower half Upper quarter
Position of pitcher hip in lower pitchers Lower third to quarter Immediately beneath peristome

In his Carnivorous Plant Database, taxonomist Jan Schlauer treats N. kongkandana as a synonym of N. mirabilis.[17]

Infraspecific taxa

Across its range, N. mirabilis exhibits great variability in terms of pitcher morphology and colour, and it has the most synonyms of all Nepenthes species.[18] The following forms and varieties of N. mirabilis have been described. With the exception of N. mirabilis var. echinostoma and N. mirabilis var. globosa, these taxa are not considered valid today.

N. mirabilis var. echinostoma

An upper pitcher of N. mirabilis var. echinostoma

Nepenthes mirabilis var. echinostoma was discovered by Odoardo Beccari in 1865 and described as a species, N. echinostoma, by Joseph Dalton Hooker in 1873.[4] In 1882, Frederick William Burbidge described this unusual variety in The Gardeners' Chronicle as follows:[4][20]

Beccari's singular N. echinostoma (vide Herb. Kew) is a wonderful thing, as yet unintroduced—indeed, I suppose unseen by any save Beccari ! The mouths of the urns remind one of the deflexed teeth of some gigantic moss of the Hypnoid section.

Nepenthes mirabilis var. echinostoma is the only form of this species that occurs in Brunei. It has also been recorded from parts of Sarawak, but appears to be completely absent from Sabah.[4]

N. mirabilis var. globosa

Nepenthes mirabilis var. globosa has been recorded from a single undisclosed Andaman Sea island off Phang Nga and from the Thai mainland near the city of Trang.[7][19]

This variety was featured on the cover of the January 2006 issue of the Journal of Insectivorous Plant Society, identified as "Nepenthes sp. from Thailand".[21] The name Nepenthes globosa appeared in print in an article by Shigeo Kurata in the July 2007 issue of the Journal of Insectivorous Plant Society.[2] The same issue also featured an article by Masahiro Tada that referred to the plant as "Nepenthes Viking".[3] Prior to its description by Marcello Catalano in 2010, this taxon was also published under the informal name Nepenthes sp. Phanga Nga in Stewart McPherson's 2009 book, Pitcher Plants of the Old World.[7]

In the horticultural trade, this variety is popularly known as both Nepenthes globosa[7] (/nɨˈpɛnθz ɡlˈbzə/; from Latin: globosus, "globular") and Nepenthes sp. Viking,[7][22] after the resemblance the pitchers bear to the prow of a Viking ship.[23]

Pitcher infauna

A great number of infaunal organisms have been found in the pitchers of this species. These include the sarcophagid fly Sarcophaga papuensis and the mite Nepenthacarus warreni, which have both been found in Australian populations of the plant.[24][25] Similarly, the mosquitoes Aedes dybasi and Aedes maehleri reside in the pitchers of N. mirabilis on the islands of Palau and Yap, respectively.[26] Both have unusual life histories and morphological traits associated with this habit.[27][28]

The nematode Baujardia mirabilis has been described from N. mirabilis in Thailand. It is not thought to be an accidental; the pitchers of this species appear to be the nematode's natural habitat. The microecosystems in these pitchers were found to be dominated by mosquito larvae, midges, and B. mirabilis. It is speculated that this nematode might have a phoretic relationship with one or more infaunal insect species.[29]

In southern China, tree frogs have been observed in the pitchers of N. mirabilis. The amphibians do not fall prey to the plant, but rather feed on insects that are caught by the pitchers.[30] They are not affected by the acidic digestive juices (which may have a pH as low as 2), likely due to the mucilagenous outer layer of their skin.[31]

The first record of an aquatic fungus living in the pitcher organ of a carnivorous plant came from a specimen of N. mirabilis growing along the Jardine River in Australia. The mycelial fungus was observerd as both free-living in the trap's fluid and attached to chitinous insect remains.[32][33]

The pitchers of N. mirabilis have also been found to harbour a complex community of bacteria.[34]

Notes

a.^ Nepenthes mirabilis was originally described as Phyllamphora mirabilis by João de Loureiro in 1790. It was then transferred to the genus Nepenthes under the incorrect combination Nepenthes phyllamphora by Carl Ludwig Willdenow in 1805. Most sources[7][15][37][40][49] attribute the earliest publication of the correct binomial, Nepenthes mirabilis, to George Claridge Druce in 1916,[50] but Jan Schlauer's Carnivorous Plant Database records a much earlier publication by Rafarin in 1869.[51]
