Hort.Westphal (2000) Nepenthes mirabilis var. smilesii (Hemsl.) Hort.Weiner in sched. (1985) 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. In 1882, Frederick William Burbidge described this unusual variety in The Gardeners' Chronicle as follows: 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. 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. 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". 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. The same issue also featured an article by Masahiro Tada that referred to the plant as "Nepenthes Viking". 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. In the horticultural trade, this variety is popularly known as both Nepenthes globosa (; from Latin: globosus, "globular") and Nepenthes sp. Viking, after the resemblance the pitchers bear to the prow of a Viking ship. 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. Similarly, the mosquitoes Aedes dybasi and Aedes maehleri reside in the pitchers of N. mirabilis on the islands of Palau and Yap, respectively. Both have unusual life histories and morphological traits associated with this habit. The nematode Baujardia mirabilis has been described from N. mirabilis in Thailand. It
