A little known Nepenthes that can only be found on the remote Waigeo Island. Waigeo is off the north-west coast of New Guinea.There the species is found at 0-320 m.a.s.l. in the lowlands. This isolated location has resulted in the species being one of those that are less closely related to most other, Southeast Asian species due to their geographic location and have been evolving independently for a long time.The upper pitchers of this species are tubular, with a broad pitcher base and edge-forming reduced wings. The base pitchers still have wings but are similar in shape.The color of the pitchers is very light, usually yellow-green with varying degrees of red blotches.Very rare, unusual species of the genus.

Nepenthes amullaria clearly belongs to the plants with an unusual growth habit. In Nepenthes ampullaria, from a certain size of the main shoot, a multitude of basals are formed, which are characterized by large pitchers on vanishingly small leaves. From a certain age onwards, this can lead to a sea of large basal pitchers being formed around the main shoot, which seem to simply stand freely.This is N. ampullaria's way of "detrivory", using detritus falling into the pitchers as fertilizer. However, these soil pots also provide habitat and shelter for many animal species. Even one of the smallest frog species discovered to date, Microhyla nepenthicola, uses the pitchersas a spawning ground.In the wild, N. ampullaria inhabits swampy forest areas in Borneo, New Guinea, Malaysia, the Maluku Islands, Singapor, Sumatra, Thailand and other small areas below 1000 m.a.s.l. This makes the species one of the most widespread of the genus.The almost spherical, laterally flattened pitchers are absolutely characteristic for this species.Extremely interesting species for every lowland setup, if the space for larger plants is given.

Large form of this wonderful species with orange pitchers. Nepenthes ampullaria clearly belongs to the plants with unusual growth habit. In Nepenthes ampullaria, from a certain size of the main shoot, a large number of basals are formed, which are characterized by large pitchers on vanishingly small leaves. From a certain age onwards, this can lead to a sea of large basal pitchers being formed around the main shoot, which seem to simply stand freely on the ground.This is N. ampullaria's way of "detrivory", using detritus falling into the pichers as fertilizer. However, these lower pitchers also provide habitat and shelter for many animal species. Even one of the smallest frog species discovered to date, Microhyla nepenthicola, uses the pots as a spawning ground. In the wild, N. ampullaria inhabits swampy forest areas in Borneo, New Guinea, Malaysia, the Maluku Islands, Singapor, Sumatra, Thailand and other small areas below 1000 m.a.s.l. (higher altitudes, however, have already been recorded). This makes the species one of the most widespread of the genus.The almost spherical, laterally flattened pitchers are absolutely characteristic for this species.Extremely interesting species for every lowland setup, if the space for larger plants is given.

Longer known as Nepenthes insignis biak form. The species received its species status as its own isolated group in 2018. It is described by the authors that Nepenthes biak should not form lower pitcher, but rather primary and secondary upper pitchers. The epithet "biak" comes from the Papuan island of the same name, which this species inhabits exclusively as an endemic. There it is found near sea level on limestone rocks or more rarely as an epiphyte on mangroves. Due to the location of only a few kilometers south of the equator and the oceanic climate, there is a constant humid climate with high temperatures all year round. Nepenthes biak is the more compact of the two species and therefore much easier to grow in limited space.
