Nepenthes northiana is a carnivorous plant from the genus of pitcher plants ( Nepenthes ). It wasfirst describedby Joseph Dalton Hooker around 1881.
description
Nepenthes northiana is a vigorous perennial and evergreen subshrub with climbing shoots that are about four meters long. The leaves of Nepenthes northiana are conical, more or less smooth and sit alternately on the shoot. They become up to 36 cm long and 20 cm wide.
The pitchers of Nepenthes northiana show a distinct dimorphism . The lower pitchers are jug-shaped with clearly fanned wing strips. The upper pitchers, on the other hand, are wide, funnel-shaped, but also have clear wing strips.
Common to both types of cans is the peristome , which is very expansive and only slightly curved backwards. Thanks to the almost vertical jug opening and the peristome, which is strongly inclined towards the rear, the jugs look as if they had been pushed in frontally with gentle force. The pitchers also stand out due to the typical striped pattern of the peristome. They are also quite large, they reach a length of up to 43 cm and are therefore larger than the jugs of Nepenthes rajah.
Flowers and seeds
The flowers of Nepenthes northiana are sexually dioecious ( diocesan ) and appear on panicles up to 70 cm long . They have four petals and are reddish in color.
Home / origin
Nepenthes northiana is mainly native to Borneo in the state of Sarawak , where it lives lithophytically on limestone cliffs . This peculiarity is otherwise known only from Nepenthes campanulata and Nepenthes mapuluensis .
Botanical history
Nepenthes northiana was captured in watercolors by the naturalist and artist Marianne North around 1880 , to which the botanist and breeder Harry Veitch became aware. This pitcher plant species was christened “Nepenthes northiana” in honor of Marianne North.
The plant was first described in 1895 by H. Beck under the name "Nepenthes spuria" . In 1925 it was named "Nepenthes decurrens" by the botanist JM Macfarlane . It was not until 1928 that Benedictus Hubertus Danser gave it its current botanical species name.
