Acrostichum aureum L. It is abundant in mangrove vegetation all over South-East Asia. In Vietnam and the Pacific, the firm, dried, parchment-like leaves are stitched together and used as thatching material in the place of straw-thatch.
In this way the roof lasts longer and there is much less risk of fire. Should the roof catch fire the leaves burn rapidly and leave very little ash, thus reducing the risk of the rest of the habitation and its furniture catching fire.
Medicinally, the pounded or grated leaves and rhizomes are applied as a paste to wounds, ulcers and boils all over South-East Asia. In China the rhizome is used against worms. The fern is collected from the wild and is commonly sold on local markets for vegetable or medicinal use.
In Vietnam leaves are locally traded as roof material. In the aboveground parts of A. In a fertility test in female albino rats, ethanolic and acetone extracts of A.
Large fern up to 4 m tall with leathery leaves, rhizomes often forming tussocks in mangrove swamps. Rhizome erect to procumbent, up to 6 mm in diameter, amply scaly at the apex; scales linear to lanceolate to broadly ovate near the petiole base, 0. Leaves tufted, erect or arching, up to 4 m long; petiole up to 1 m long, at the base up to 20 mm in diameter, lustrous, stramineous to grey-brown, glabrous, bearing on upper portion small spine-like remains of reduced glandular pinnae; lamina pinnate, narrowly oblong to elliptical, up to 3 m long, subcoriaceous to coriaceous, glabrous, bright red when young; sterile pinnae simple, ascending, stalk up to 2.
Individual growth of A. It prefers open areas; its growth is inhibited under a dense mangrove forest canopy, but where there is a dense A.
In mangrove reforestation programmes, A. There are 3 species in the genus, the third one A. Acrostichum L. In Muara Pasir, East Kalimantan Indonesia it tends to be a noxious weed in the mangrove forest, which is dominated by Avicennia officinalis L.
Dense growth of A. There is one extraordinary record of A. Young plants are often found in sheltered locations on rocky shores, but in such positions they rarely attain any size. Natural propagation and regeneration of A.
Vegetative propagation is possible by clump division and by rhizome cuttings. Large plants are generally intolerant of disturbance, whereas small specimens will adapt to cultivation readily. Full sunlight and plenty of moisture are required throughout its growth. It is also possible to grow A. A recommended potting mix is a ratio of of vegetable mould, sand and leaf mould respectively with pH 5.
No germplasm collections nor breeding programmes are known to exist for A. Because it is a pantropical fern species, often occurring as a weed, there is up to now no danger of extinction. The natural habitats of this fern are facing serious destruction due to the accelerated exploitation of mangrove areas for timber and firewood or conversion of the land for other purposes.
