Cyathea biliranensis is a species of fern in the family Cyatheaceae, native to the Philippines. [1] It was first described by Edwin Copeland in 1955. [2]
Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales.
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.
Sphaeropteris is a genus of tree fern in the family Cyatheaceae. It has been treated as a subgenus within the genus Cyathea, but is accepted in the Pteridophyte Phylogeny Group classification of 2016.
Gymnosphaera biformis, synonyms Alsophila biformis and Cyathea biformis, is a species of tree fern native to New Guinea and the Maluku Islands, where it grows against trees in mossy forest and rain forest at elevations of 850–2200 m. The climbing trunk is very thin, only 1–2 cm in diameter, but can reach 3 m in height. The apex of the trunk is covered in scales. Two types of fronds are produced, simple pinnate fronds, which are sterile, and bipinnate fronds, which may be fertile. The stipe is smooth, glossy and very dark, almost to the point of being black. It is covered at the base with long, very dark scales that have a pale margin. Fertile pinnules are distinctly stalked and lobed. Sori occur in four pairs per pinnule lobe and lack indusia.
Alsophila brooksii, synonym Cyathea brooksii, is a species of tree fern native to Cuba, Hispaniola and Puerto Rico, where it grows on serpentine soils in shaded ravines, along streams, and on forested slopes at an altitude of 250–950 m. The trunk is prostrate and only about 6 cm in diameter. Fronds are pinnate or bipinnate and up to 2 m long. The base of the rachis is covered with blackish scales that have a paler margin. Sori occur in two rows, one along each side of the pinnule midvein.
Cyathea aristata is a species of fern in the family Cyatheaceae, native to Mexico and Colombia. It was first described by Domin in 1930.
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 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.
Gymnosphaera hornei is a species of tree fern in the Cyatheaceae family.
Sphaeropteris elmeri, synonym Cyathea elmeri, is a species of tree fern native to the Philippines, Talaud Islands, and northern Sulawesi, where it grows in forest at an altitude of 500–1400 m. The trunk of this plant is erect and 5–10 m tall. Fronds may be bi- or tripinnate and up to 2 m or more in length. The lower surface of the rachis is distinctively pale and warty. The stipe is covered with scales and has warts towards the base. The scales are large, tapering, thin, and medium brown in colouration. Sori are borne near the fertile pinnule midvein. Indusia are absent.
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.
Gymnosphaera podophylla, synonyms Alsophila podophylla and Cyathea podophylla, is a widespread species of tree fern native to southern China, Hainan, Taiwan, Vietnam, Laos, Myanmar, Thailand, Cambodia, the Ryukyu Islands, and Japan. It grows in forest by streams and in ravines at elevations of 600–1000 m.
Dennstaedtia is a mostly tropical and subtropical genus of ferns described as a genus in 1801. hayscented fern, or cup ferns, are common names for some species in this genus. Its best-known member is probably the temperate North-American hay-scented fern, Dennstaedtia punctilobula, which forms extensive clonal ground-cover colonies on level surfaces in the Appalachian area.
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.
