Alsophila australis is a robust tub plant and tolerant of salty winds. It is a popular cool climate hardy tree-fern, adaptable to a variety of climates and soils. It grows in moist shady forest, both coastal and montane, at an altitude up to 1,280 m (4,200 ft), often in the company of Dicksonia antarctica.
The tree ferns are arborescent (tree-like) ferns that grow with a trunk elevating the fronds above ground level, making them trees. Many extant tree ferns are members of the order Cyatheales, to which belong the families Cyatheaceae (scaly tree ferns), Dicksoniaceae, Metaxyaceae, and Cibotiaceae. It is estimated that Cyatheales originated in ...
Nunniong, Australia. The soft tree fern can be used as a food source, with the pith of the plant being eaten either cooked or raw. It is a good source of starch. [4] The 1889 book The Useful Native Plants of Australia records that "The pulp of the top of the trunk is full of starch, and is eaten by the aboriginals [sic.] both raw and roasted ...
R.M.Tryon [1] Sphaeropteris excelsa, synonym Cyathea brownii, [2] commonly known as the Norfolk tree fern or smooth tree fern, is probably the largest fern species in the world. It is endemic to Norfolk Island, in the Pacific Ocean near Australia and New Zealand. It is named after the botanist Robert Brown (1773-1858).
L'Hér. See text. Dicksonia is a genus of tree ferns in the order Cyatheales. It is regarded as related to Cyathea, but is considered to retain more primitive traits, dating back at least to the Jurassic and Cretaceous periods. The fossil record includes stems, pinnules, and spores. The genus contains 20–25 species, distributed from Mexico to ...
The order Cyatheales, which includes most tree ferns, is a taxonomic order of the fern class, Polypodiopsida. [2] No clear morphological features characterize all of the Cyatheales, but DNA sequence data indicate the order is monophyletic. Some species in the Cyatheales have tree-like growth forms from a vertical rhizome, others have shorter or ...
Dicksonia youngiae, common name bristly tree fern, is a fern that comes from cool, sheltered rainforests in New South Wales and Queensland, Australia. It is found north of the Bellinger River, in New South Wales, and can be seen in the wild at Nightcap National Park. Similar to D. squarrosa, it sends up multiple trunks and can grow 4 m high.
Hymenophyllum australe, commonly known as austral filmy fern, [1] is a relatively large rupestral and epiphytic fern, indigenous to eastern Australia [2] and New Zealand. [3] It belongs to the unique Hymenophyllum genus (filmy ferns), which are characterised by their thin membranous fronds that are seldom more than one cell thick, with the exception of regions over and around veins.
