Characteristics

A tree fern. It grows to 6 m high. The crown can be 12 m across. The erect rhizome or trunk can be 1 m high and 80 cm across in older plants. This trunk is fleshy with thick fleshy roots. It can just have a tuft of leaves coming from near ground level. Because there is no hard tissue, the water pressure inside the stalk keeps the leaves erect. This frond will therefore collapse in dry weather. Where the stem of the frond joins the trunk is a large ear-shaped leafy structure (stipule). The leaves are 2-7 m long and 1-2.5 m wide. The leaves can be divided 2 to 4 times. The small leaflets are 13 cm long and finely toothed around the edge. There are 3-7 pairs of spore bearing organs in double rows along the veins. The fronds are very fleshy and contain a lot of starch.
More
Fronds to 5 m or more long, arching. Stipe to 2 m long, up to two-thirds of leaf length, ± smooth. Lamina 2-pinnate, deltoid, to 3.2 m long and 2.5 m wide. Pinnae ± linear-lanceolate, alternate, c. 9 pairs, to 150 cm long and 45 cm wide. Pinnules 29–40 pairs, opposite to subopposite, sometimes becoming alternate towards pinna apex, to 30 cm long and 2 cm wide, ± parallel-sided; base unequal to cuneate; margins scarcely serrulate; apex long-acuminate and more strongly toothed. Sori submarginal, with 10–15 sporangia.
Fronds 2-5 m; stipes smooth. Laminae bipinnate; pinnae 65-70 cm, with 15-30 pairs of spreading pinnules; pinnules 7-20 × 0.9-3.5 cm, bases cordate, rounded to cuneate, margins crenulate to serrate, apices acuminate to caudate. Veins obvious, false veins obvious, extending nearly to costule. Sori marginal to ca. 1 mm from margin, ca. 2 mm, with 8-10 sporangia.

Environment

A tropical plant. It is a lowland forest plant. They grow naturally on fertile, moist soil in the rain forest. Often they are near streams and waterfalls. It suits humid locations. They commonly grow in partial shade. They grow from sea level to 700 m altitude. In the Himalayas it grows up to 2,100 m above sea level. They can survive some frost once plants are 3-4 years old. They cannot tolerate dry conditions. In Adelaide Botanical Gardens hot house. It suits hardiness zones 10-12.
More
Deep shade of the forest floor, usually near a stream or within a drainage channel where it often becomes submerged.
Grows in clay or sandy soil on banks and in gullies in rainforest, from 7–290 m altitude.

Usage

The young fiddle heads or unopened young fronds are eaten. The swollen leaf base is mixed with other vegetables. Flour can be made from the stalks and rhizomes.

Cultivation

They are normally grown from the stipules or leafy structure at the base of the leaflet. It may take 12-18 months for the shoots to form. It is difficult to grow this fern from spores. Small plantlets already developing from the base of the fronds can be removed and planted.
