Nepenthes Maxima

Nepenthes maxima (; from Latin: maximus "greatest"), the great pitcher-plant, is a carnivorous pitcher plant species of the genus Nepenthes. It has a relatively wide distribution covering New Guinea, Sulawesi, and the Maluku Islands. It may also be present on Wowoni Island.

Nepenthes maxima belongs to the loosely defined "N. maxima complex", which also includes, among other species, N. boschiana, N. chaniana, N. epiphytica, N. eymae, N. faizaliana, N. fusca, N. klossii, N. platychila, N. stenophylla, and N. vogelii.

Variability

This species exhibits great variability across its range, particularly in the plasticity of its pitchers. Plants growing in drier, somewhat seasonal parts of New Guinea generally produce elongated pitchers with narrow peristomes and well-developed waxy zones, while those inhabiting perhumid areas often have a reduced waxy zone and enlarged peristome. This is thought to be because the peristome, when fully wetted, is more effective at trapping prey than the waxy zone, but performs poorly in drier conditions.
