Description
Neuwiedia zollingeri grows as a perennial herbaceous plant, reaching heights of growth from 45 to 70 cm. The roots arise both in the soil and above ground to the stem axis. The aerial roots have a diameter from 2.5 to 4 mm and at the ends they are sometimes thickened. Sometimes the roots are hairy. The leaves are lanceolate to linear, their size varies greatly, ranging in length 4-53 cm, in width from 1 to 7.5 cm. The leaf blade contains seven to 55 longitudinal veins, seven of which stand out clearly.
It is formed a terminal, racemose inflorescence. With the variety Neuwiedia zollingeri var zollingeri he is hairless, with 7-9 cm quite short, he carries 40 to 80 flowers. De Vogel reports of flowering plants in February, March and July. The variety Neuwiedia zollingeri var javanica distinguished by the hairy inflorescence is up to 17 cm long and contains 30 to 60 flowers. The coat can vary in glands and glandular hairs loose, the glandular hairs are found mainly on the petals. In this variety the whole year there are about flowering plants. The bracts of the flowers are lanceolate to linear, pointed ending, 10 to 35 mm long and 2-8 mm wide. The flower stalk is 2-5 mm long.
The fruit is a white berry-like, fleshy, with ripe but probably dehiscent capsule fruit. It is round and measures 6-9 mm in diameter, the length is 8 to 10 mm plus a 2 to 3 mm long patch tip.
