A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns.
Elkhorn or Elk Horn may refer to:
Platycerium is a genus of about 18 fern species in the polypod family, Polypodiaceae. Ferns in this genus are widely known as staghorn or elkhorn ferns due to their uniquely shaped fronds. This genus is epiphytic and is native to tropical and temperate areas of South America, Africa, Southeast Asia, Australia, and New Guinea.
Fossil Butte National Monument is a United States National Monument managed by the National Park Service, located 15 miles (24 km) west of Kemmerer, Wyoming, United States. It centers on an assemblage of Eocene Epoch animal and plant fossils associated with Fossil Lake—the smallest lake of the three great lakes which were then present in what are now Wyoming, Utah, and Colorado. The other two lakes were Lake Gosiute and Lake Uinta. Fossil Butte National Monument was established as a national monument on October 23, 1972.
The Bukit Timah Nature Reserve is a 1.7-square-kilometre (0.66 sq mi) nature reserve near the geographic centre of Singapore, located on the slopes of Bukit Timah Hill, the country's highest natural peak standing at a height of approximately 165-metre (541 ft), and parts of the surrounding area. The nature reserve is about 15 kilometres from the Downtown Core, Singapore's central business district (CBD).
Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016, the family includes around 65 genera and an estimated 1,650 species and is placed in the order Polypodiales, suborder Polypodiineae. A broader circumscription has also been used, in which the family includes other families kept separate in PPG I. Nearly all species are epiphytes, but some are terrestrial.
Ganna Walska Lotusland, also known as Lotusland, is a non-profit botanical garden located in Montecito, near Santa Barbara, California, United States. The garden is the historic estate of Madame Ganna Walska. The County of Santa Barbara restricts visitation via a conditional use permit: Lotusland botanic garden is open to the public by advance reservation only, with walking tours 1½ to 2 hours long.
Athyrium (lady-fern) is a genus of about 180 species of terrestrial ferns, with a cosmopolitan distribution. It is placed in the family Athyriaceae, in the order Polypodiales. Its genus name is from Greek a- ('without') and Latinized Greek thyreos ('shield'), describing its inconspicuous indusium . The common name "lady fern" refers in particular to the common lady fern, Athyrium filix-femina.
The greater Brisbane area of Queensland Australia, has many species of indigenous flora. This article links the flora to its geography with:
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.
Platycerium superbum, commonly known as the staghorn fern, is a Platycerium species of fern. It is native to Australia.
Davallia solida var. pyxidata known as the hare's foot fern, is a variety of fern that occurs in eastern Australia and is usually identified as a lithophyte or epiphyte in or near rainforest areas. However, it may also be seen in a few locations west of the Great Dividing Range. Listed as vulnerable in Victoria, occurring in the Grampians.
Aglaomorpha is a genus of ferns in the subfamily Drynarioideae of the family Polypodiaceae. The Pteridophyte Phylogeny Group classification of 2016 uses this genus name, while other sources use Drynaria to include Aglaomorpha. Species are commonly known as basket ferns. As circumscribed in PPG I, the genus contains around 50 species.
Polypodioideae is a subfamily belonging to the fern family Polypodiaceae, which is a member of the suborder Polypodiineae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the subfamily may be treated as the tribe Polypodieae within a very broadly defined family Polypodiaceae sensu lato.
Platycerioideae is a small subfamily of the fern family Polypodiaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The subfamily is also treated as the tribe Platycerieae within a very broadly defined family Polypodiaceae sensu lato.
Platycerium hillii is a species of staghorn fern in the genus Platycerium. It is found in Australia.
Platycerium grande, the giant staghorn fern, capa de leon, and dapong repolyo, is a species of epiphytic fern in the family Polypodiaceae. It is one of the two staghorn ferns native to the Philippines, along with P. coronarium, and is endemic to the island of Mindanao, in the provinces of Zamboanga, Lanao and Davao. P. grande is often collected from the forests and sold as a highly prized ornamental plant. Due to overcollection and the difficulty of the spores to germinate under natural conditions, in vitro technique is necessary to ensure mass production of this plant species. The local government categorized it as critically endangered species.
Platycerium veitchii, called the silver elkhorn fern or the silver staghorn fern, is a species of fern in the family Polypodiaceae, native to Queensland. It has gained the Royal Horticultural Society's Award of Garden Merit as an ornamental.
Chimarra alcicorne is a species of fingernet caddisfly in the family Philopotamidae. It is found in South Asia.
