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. [1]
The fern has a 20–30 cm high trunk. Its 2- or 3-pinnatifid fronds are 0.5–1 m long and 30–45 cm wide. [1]
The fern is endemic to Australia’s subtropical Lord Howe Island in the Tasman Sea; it only occurs on the summit of Mount Gower at the southern end of the island. [1]
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, Dicksoniaceae, Metaxyaceae, and Cibotiaceae. 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 were the Psaroniaceae and Tietea in the Marattiales, which is the sister group to most living ferns including Cyatheales.
Passiflora herbertiana, or native passionfruit, is a widespread climbing twiner native to moist forests on the coast and ranges of eastern Australia. The subspecies P. h. insulae-howeiP.S.Green is endemic to Lord Howe Island in the Tasman Sea.
Zealandia pustulata is a species of fern native to eastern Australia and New Zealand. It is commonly referred to as kangaroo fern because of its mature leaves tend to resemble the shape of a kangaroo foot. It is also referred to as hound's tongue, and as kōwaowao and pāraharaha in Māori.
Dendrobium moorei, commonly known as the drooping cane orchid, is a species of epiphytic or lithophytic orchid in the family Orchidaceae and is endemic to Lord Howe Island. It has cylindrical pseudobulbs, leathery, dark green leaves and between two and fifteen small, white drooping flowers that do not open widely.
Hymenophyllum moorei is a rare species of filmy fern in the family Hymenophyllaceae. It is endemic to the high cloud forest at Mount Gower and Mount Lidgbird at Lord Howe Island. A small epiphytic fern found usually on tree trunks and fallen logs.
Leptopteris fraseri, commonly known as the crepe fern, is a species of plant occurring in eastern Australia. Its habitat is wet places, mostly on the Great Dividing Range. It is found in caves, near waterfalls, in dark shady places in the cooler rainforests.
The fern genus Leptopteris is a small group of plants found growing in the Pacific Islands, New Guinea and Australia. They are similar to ferns in the related genus Todea, and were originally included in that genus. However, the very thin fronds of Leptopteris differ from the thick leathery fronds of Todea, and the genera are considered distinct. A probable extinct species, Leptopteris estipularis is known from the Early Cretaceous of India.
Lomaridium contiguum, synonym Blechnum contiguum, is a fern in the family Blechnaceae. The specific epithet refers to the contiguous lobes of the fronds.
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.
