Lomaridium contiguum, synonym Blechnum contiguum, is a fern in the family Blechnaceae. The specific epithet refers to the contiguous lobes of the fronds. [2]
The plant is a climbing epiphytic fern. Its rhizome is long and covered with dense, narrowly lanceolate scales. Its fronds are 30–50 cm or more long and 5–12 cm wide. [2]
The fern is found on Australia's subtropical Lord Howe Island in the Tasman Sea, as well as on New Caledonia. On Lord Howe it is common in the cloud forest on the summits of Mounts Gower and Lidgbird. [2]
The tree ferns are arborescent (tree-like) ferns that grow with a trunk elevating the fronds above ground level, making them trees. Most tree ferns are members of the "core tree ferns", belonging to the families Cyatheaceae, Dicksoniaceae, Metaxyaceae, and Cibotiaceae in the order Cyatheales. It is estimated that Cyatheales originated in the early Jurassic, and is the third group of ferns known to have given rise to tree-like forms. The others are the extinct Tempskya of uncertain position, and Osmundales where the extinct Guaireaceae and some members of Osmundaceae also grew into trees. In addition there was the Psaroniaceae and Tietea in the Marattiales, which is the sister group to true ferns.
Cranfillia fluviatilis, synonym Blechnum fluviatile, is a fern known in the Māori language as kiwikiwi. A herbaceous plant, C. fluviatilis is a "hard fern" of the genus Cranfillia in the family Blechnaceae. It was identified by Patrick Brownsey in 1979. Other common names are star fern, creek fern, kawakawa and kiwakiwa.
Doodia media, also known as rasp fern, is a fern species in the family Blechnaceae. The species was formally described by botanist Robert Brown in 1810. Distribution of the species includes New Zealand's North Island and the upper part of the South Island. It is also found in Australia and Lord Howe Island.
Platycerium bifurcatum, the elkhorn fern or common staghorn fern, is a species of fern native to Java, New Guinea and eastern Australia, in New South Wales, Queensland and on Lord Howe Island. It is a bracket epiphyte occurring in and near rainforests. Growing to 90 cm (35 in) tall by 80 cm (31 in) broad, it has heart-shaped sterile fronds 12–45 cm (5–18 in) long, and arching grey-green fertile fronds which are forked and strap-shaped, and grow up to 90 cm (35 in) long.
Parablechnum wattsii, synonym Blechnum wattsii, is a common terrestrial fern growing in rainforest and open forest. It is often seen near creeks in much of south eastern Australia, including Victoria, Tasmania, South Australia, New South Wales and Queensland. The specific epithet wattsii honours William Walter Watts (1856-1920). Watts was considered an authority on mosses and ferns and has more than 30 species named for him. Common names by which the species may be called are hard water fern - from its stiff leathery fronds, leech fern - as forest workers often encounter leaches while working in clusters of these ferns, hard hill fern - from the fern's habit and habitat, and red cabbage fern - from the bronze-pink colour of the young fronds resembling cooked red cabbage.
Lomaria nuda, commonly known as the fishbone waterfern, is a fern that grows up to a metre tall, and is abundant in rainforest and eucalyptus forests in eastern Australia. The species is placed in the genus Lomaria in the Pteridophyte Phylogeny Group classification of 2016, but is often retained in genus Blechnum as Blechnum nudum.
Cranfillia fullagari, synonym Blechnum fullagarii, is a fern in the family Blechnaceae. The specific epithet honours James Fullagar, who collected plants on Lord Howe Island for the Royal Botanic Gardens, Melbourne.
Cranfillia geniculata, synonym Blechnum geniculatum, is a fern in the family Blechnaceae. The specific epithet refers to the geniculate base of the sterile fronds.
Parablechnum howeanum, synonym Blechnum howeanum, is a fern in the family Blechnaceae. The specific epithet refers to the locality to which it is endemic.
Alsophila ferdinandii, synonym Cyathea macarthurii, is a fern in the family Cyatheaceae.
Lastreopsis nephrodioides is a fern in the family Dryopteridaceae. The specific epithet refers to its resemblance to Nephrodium decompositum R.Br..
Polystichum moorei is a fern in the family Dryopteridaceae. The specific epithet honours Charles Moore, Director of the Royal Botanic Gardens, Sydney, from 1848 to 1896, who collected plants on Lord Howe Island in 1869.
Polystichum whiteleggei is a fern in the family Dryopteridaceae. A former common name was heavy fern, alluding to the weight of one of the large, thick textured, fronds when fully developed. The specific epithet honours Thomas Whitelegge (1850–1927) of the Australian Museum, who collected zoological specimens on Lord Howe Island in 1887, who first noticed the fern's distinctiveness.
Grammitis diminuta is a fern in the family Polypodiaceae. The Latin specific epithet diminuta means "decreased" or "diminished", with reference to the tapered frond base.
Grammitis nudicarpa is a fern in the family Polypodiaceae.
Grammitis wattsii is a fern in the family Polypodiaceae. The specific epithet honours the Reverend W. W. Watts (1856–1920), a prominent Australian cryptogamist active in the late 19th and early 20th centuries.
Callistopteris bauerianum, known as the large filmy fern and Bauer's bristle fern, is a fern in the family Hymenophyllaceae. The specific epithet honours the Austrian botanical artist, Frederick Lucas Bauer (1760–1826), who collected plants on Norfolk Island in 1804–1805.
Hymenophyllum howense is a fern in the family Hymenophyllaceae. The specific epithet refers to the locality of occurrence.
Leptopteris moorei is a fern in the family Osmundaceae. The specific epithet honours Charles Moore, Director of the Royal Botanic Gardens in Sydney from 1849 to 1896, who collected plants on Lord Howe Island in 1869.
Lomaridium is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, according to the Pteridophyte Phylogeny Group classification of 2016. The genus is accepted in a 2016 classification of the family Blechnaceae, but other sources sink it into a very broadly defined Blechnum, equivalent to the whole of the PPG I subfamily.
