Nepenthes neoguineensis is a carnivorous plant belonging to the genus pitcher plants ( Nepenthes ). It wasfirst describedin 1911 by the botanist John Muirhead Macfarlane . Its specific epithet "neoguineensis" is an allusion to the origin of this species, namely New Guinea .

description

Nepenthes neoguineensis is a perennial , evergreen subshrub whose climbing shoots reach several meters in length and become lignified with age. The plant often sprouts young shoots from the wood . The leaves of Nepenthes neoguineensis are leathery, broadly elliptical in shape and sit alternately on the shoot. They become up to 35 cm long.

Upper jug

The jugs of Nepenthes neoguineensis show a clear dimorphism : The lower jugs are cup-shaped and have a slightly oversized lid. The wing strips are broadly expansive and decorated with fine eyelashes.

The top jugs are wide and funnel-shaped, also have large, sweeping wing strips and narrow, heart-shaped lids. The peristome is slightly narrower on the upper pitchers than on the lower ones. Both types of can have a distinctive veining. The color of the pitchers is very variable.

Inflorescence and fruits

blossoms

The flowers of Nepenthes neoguineensis are separately dioecious ( dioecious ) and appear on a panicle up to 44 cm long . They have four petals and can be reddish, or deep burgundy when exposed to intense sunlight. Their diameter is 8 mm.

Home / origin

The species originates from New Guinea , where it inhabits thinly forested or bush-rich wet savannahs at altitudes of 900 to 1400 meters. Nepenthes neoguineensis is one of the few pitcher plant species that can tolerate full sun.

Botanical history

In 1910 the botanist John Muirhead Macfarlane was touring New Guinea and came across Nepenthes neoguineensis . He marveled at the unusual appearance of the plant and brought the first specimens to Europe.

Nepenthes neoguineensis is closely related to Nepenthes papuana , which lives in the same range.

Their appearance is very similar to Nepenthes paniculata , although their air cans have no ciliate wings and are significantly slimmer.
