Cyathea aristata is a species of fern in the family Cyatheaceae, native to Mexico and Colombia. [1] It was first described by Domin in 1930. [2]
Pinus aristata, the Rocky Mountain bristlecone pine, is a long-living species of bristlecone pine tree native to the United States. It appears in the Rocky Mountains in Colorado and northern New Mexico, with isolated populations in the San Francisco Peaks in Arizona and the Kaibab National Forest north of the Grand Canyon. It is usually found at very high altitudes, from 7,000–13,000 feet (2,100–4,000 m), in cold, dry subalpine climate conditions, often at the tree line, although it also forms extensive closed-canopy stands at somewhat lower elevations.
Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales.
Karel Domin was a Czech botanist and politician.
Cyathea affinis is a variable species of tree fern native to Fiji, Samoa, the Cook Islands, Austral Islands, Tahiti, and the Marquesas Islands. The trunk of this plant is erect and 2–6 m tall. Fronds are bipinnate and 2–3 m in length. The rachis and stipe are pale to brown in colour, or flushed with red towards the pinnule rachis. The stipe is sparsely covered in narrow basal scales, which are pale to dark and have broad fragile edges. Characteristically of this species, the lowest one or two pairs of pinnae may be slightly reduced and occur towards the base of the stipe. Sori are located near the pinnule midvein and are partially or fully covered by indusia, which open towards the pinnule margin.
Gymnosphaera baileyana, synonyms Alsophila baileyana and Cyathea baileyana, also known as the wig tree fern, is a species of tree fern native to northeastern Queensland in Australia, where it grows in wet gullies and forest at an elevation of 850–1200 m. It is a rare species that is seldom found in the wild. The erect trunk is 4–5 m tall, approximately 10 cm in diameter and may be covered in stipe bases in the upper regions. C. baileyana is notable for being able to develop offshoots from the base of the trunk. Fronds are bi- or tripinnate and may be exceptionally long, up to 7 m, though they are usually around 2–3 m. The rachis and stipe are dark to darkish red, scaly and may be warty, but lack spines. Scales on the rachis and stipe are purplish brown to black and have a long hair-like apex. Characteristically of this species, the last pair of pinnae are separated from the others along the rachis and may form a clump around the trunk apex. Sori are circular and occur in one to three rows along the pinnule midvein. They lack indusia.
Alsophila hermannii, synonym Cyathea christiiCopel., is a species of tree fern endemic to Mindanao in the Philippines, where it grows in forest at an altitude of 900–1800 m. The trunk is erect and may be 5 m tall or more. Fronds are bi- or tripinnate and 2–3 m long. The stipe is covered with some warts and narrow, brown scales. Sori occur near the midvein of fertile pinnules and are covered by thin, fragile indusia.
Cyathea decora is a species of tree fern native to Ecuador and possibly other parts of western South America. Little is known about this species. The name is the source of some taxonomic confusion: as of July 2021, Plants of the World Online regarded "Cyathea decora" as an unplaced name, and it was not listed at all in World Ferns.
Cyathea feeana is a species of fern in the family Cyatheaceae, native to Southeast Brazil. It was first described by Carl Christensen in 1905 as Alsophila feeana.
Alsophila costalisora, synonym Cyathea costalisora, is a species of tree fern native to western New Guinea, where it grows on the edges of forest and in moist hollows at an altitude of 1900–3225 m. The trunk is erect, up to 4 m tall and may branch near the base. Fronds are bi- or tripinnate and 1–1.5 m long. The stipe is warty, especially where scales have fallen. The scales are pale and have a distinctive dark glossy central region, with a paler dull margin. Sori are round and occur near the fertile pinnule midvein. They are covered by firm, dark indusia that are cup-like in appearance.
Alsophila dryopteroides, synonym Cyathea dryopteroides, is a tree fern native to Puerto Rico, where it grows where it grows in shaded areas and cloud forest at an altitude of 1000–1200 m. The erect trunk may be 1.3 m tall and approximately 5 cm in diameter. Fronds are pinnate and up to 1.6 m long. The rachis is often purplish brown and covered with scales, usually on the underside. The scales range in colour from golden brown to bicoloured. Sori occur along each side of the pinnule midvein and indusia are cup-like.
Cyathea biliranensis is a species of fern in the family Cyatheaceae, native to the Philippines. It was first described by Edwin Copeland in 1955.
Alsophila is a genus of tree ferns in the family Cyatheaceae. It has also been considered to be a section in the subgenus Cyathea of the genus Cyathea.
Alsophila glaucifolia, synonym Cyathea glauca, is a species of tree fern endemic to Réunion. Little is known about this species.
Cyathea obtusa is a species of fern in the family Cyatheaceae, native to Trinidad and Tobago, Venezuela, and the Windward Islands. It was first described by Domin in 1929.
Protea aristata is a compact shrub with beautiful flowers which is endemic to the southwestern part of the Cape Region of South Africa. P. aristata has become one of South Africa's most famous proteas in spite of its relatively late discovery, and re-discovery in 1953. The leaves are soft, dense and needle-like and the flower heads are a stunning crimson red, it may thus be a good potential ornamental plant for South African gardens. It is usually called the Ladismith sugarbush in South African English, although it has been called pine sugar bush in Australia. In the Afrikaans language it has the vernacular name of klein-den-suikerbos.
Gaillardia aristata is a North American species of flowering plant in the sunflower family, known by the common names common blanketflower and common gaillardia. This perennial wildflower is widespread across much of North America, from Yukon east to Québec and south as far as California, Arizona, Illinois, and Connecticut, although it may be naturalized rather than native in parts of that range. It is also naturalized in scattered locations in Europe, Australia, and South America.
Hygroryza (watergrass) is a monotyipic genus of Asian flowering plants in the grass family. The only known species is Hygroryza aristata, native to China, Bangladesh, Cambodia, India, Laos, Malaysia, Myanmar, Nepal, Pakistan, Sri Lanka, Thailand, Vietnam.
Alsophila leichhardtiana, synonym Cyathea leichhardtiana, the prickly tree fern, is a plant in the tree fern family, Cyatheaceae, found in eastern Australia. It is a common species found in moist situations, in and near rainforests. It was named in honour of the explorer and botanical collector Ludwig Leichhardt.
Cyathea dichromatolepis is a species of fern in the family Cyatheaceae, native to Southeast Brazil. It was first described by Fée in 1869 as Alsophila dichromatolepis.
