Freycinetia banksii grows as a densely branched, woody climbing plant, so it is a liana . The shoot axes have a diameter of up to 40 millimeters and lengths of about 30 meters and form abundant aerial roots . The stem axis climbs trees or forms a dense undergrowth on the forest floor. Their shoot axes and leaves are a characteristic image in many New Zealand forests. The leaves are long and narrow, about 60 to 90 inches long and 2 to 2.5 inches wide.

The chromosome number is 2n = 62.

Occurrence

Freycinetia banksii is common in New Zealand in forests all over the North Island . In the South Island , it is more common in areas with higher rainfall and reaches its southern limit of distribution near the Clarence River in the east and in Fiordland in the west.

Taxonomy

A synonym for Freycinetia banksii A.Cunn. is Freycinetia baueriana subsp. banksii (A.Cunn.) BCStone .

In 1973 Benjamin C. Stone argued that Freycinetia banksii should be regarded as a subspecies of the Freycinetia baueriana spread on Norfolk Island . De Lange et al. contradicted Stone's arguments and kept Freycinetia banksii as a separate species because they have significant differences. These include the general appearance, the orientation of the leaves ( phyllotaxis ), leaf width, the arrangement of the leaf veins and the color of the bracts (salmon-colored to orange in Freycinetia baueriana , purple in Freycinetia banksii ).

use

The sweet fruits (Māori: pātangatanga or ureure ) and the juicy bracts of the inflorescences (Māori: tāwhara) were a Māori delicacy . The leaves were widely used for braiding and weaving, although the wider leaves of New Zealand flax were preferred. Mats and baskets were made for storing food. The aerial roots were collected as binding material and to make fish traps and sandals.
