Question: Are Cyathea and Carpobrotus similar plants?

full_context: Document 1: Lithops: Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words λίθος ("lithos"), meaning "stone," and ὄψ ("ops"), meaning "face," referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. The formation of the name from the Greek "-ops" means that even a single plant is called a Lithops.
Document 2: Hoodia gordonii: Hoodia gordonii, also known as Bushman's hat, is a leafless spiny succulent plant supposed to have therapeutic properties in folk medicine. It grows naturally in Botswana, South Africa and Namibia. The species became internationally known and threatened by collectors, after a marketing campaign falsely claimed that it was an appetite suppressant for weight loss. The flowers smell like rotten meat and are pollinated mainly by flies. The indigenous San people (Bushmen) of the Namib desert call this plant ǁhoba (pronounced – the initial sound is a lateral click) – and the Afrikaans name ghaap is used to refer to all species of "Hoodia".
Document 3: Ceropegia: Ceropegia is a genus of plants within the family Apocynaceae, native to Africa, southern Asia, and Australia. It was named by Carl Linnaeus, who first described this genus in volume 1 of his "Species plantarum", which appeared in 1753. Linnaeus thought that the flowers looked like a fountain of wax. From this the scientific name was derived: ‘"keros"’ meaning wax and ‘"pege"’ meaning fountain (Pooley, 1998). They have many common names including lantern flower, parasol flower, parachute flower, bushman’s pipe, string of hearts, snake creeper, wine-glass vine, rosary vine, and necklace vine.
Document 4: Colobanthus: Colobanthus is a large genus of small, cushion-like herbaceous plants, sometimes known as "pearlworts", a name they share with plants of the related genus "Sagina". "C. quitensis" is the world's southernmost dicot, and one of only two original flowering plants of Antarctica.
Document 5: Cyathea fulgens: Cyathea fulgens is a species of tree fern native to Cuba, Jamaica and Hispaniola. It forms part of the complex centered on "Cyathea woodwardioides" comprising six very similar taxa from the Greater Antilles. The other five species are "Cyathea crassa", "Cyathea grevilleana", "Cyathea portoricensis" and "Cyathea tussacii". Large and Braggins (2004) note that this group is known to cross with members of the "Cyathea minor" complex. In the wild, "C. fulgens" also forms hybrids with "Cyathea brooksii".
Document 6: Cyathea chinensis: Cyathea chinensis is a species of tree fern native to Yunnan in China, Sikkim in India, as well as Nepal, Myanmar, Laos and Vietnam. Plants grow in forest and montane forest at an altitude of 900-1800 m. The trunk is erect and 1-2 m tall. Fronds are bipinnate and 1-2 m long. The stipe is either long and warty or has short spines towards the base as well as scattered glossy dark brown scales with fragile edges. Sori occur near the midvein of fertile pinnules and are covered by thin indusia.
Document 7: Dicksonia: Dicksonia is a genus of tree ferns in the order Cyatheales. It is regarded as related to "Cyathea", but is considered more primitive, dating back at least to the Jurassic and Cretaceous periods. The fossil record includes stems, pinnules, and spores.
Document 8: Cyathea: Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales.
Document 9: Carpobrotus: Carpobrotus, commonly known as pigface, ice plant, sour fig, and Hottentot fig, is a genus of ground-creeping plants with succulent leaves and large daisy-like flowers. The name refers to the edible fruits. It comes from the Ancient Greek "karpos " "fruit" and "brotos " "edible".
Document 10: Croton glandulosus: Croton glandulosus has many common names such as vente conmigo, tooth-leaved croton, tropic croton and sand croton. It is part of the Euphorbiaceae family which is also known as the Spurge Family and it contains about 321 genera and 7,950 species. The family derives its name from Euphorbus who was a Trojan War hero in Greek mythology, and was also the Greek Physician of King Juba of Numidia. The genus, Croton, is derived from Greek, meaning “tick,” and this is because the seeds of the plant resemble a tick. The species, glandulosus gets its name from the gland like structures that appear at the end of the leaf stalk. Vente conmigo and various others species are found to be common weeds in gardens and lawns.
Document 11: Athyrium: 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.
Document 12: Salicornia: Salicornia is a genus of succulent, halophyte (salt tolerant) flowering plants in the family Amaranthaceae that grow in salt marshes, on beaches, and among mangroves. "Salicornia" species are native to North America, Europe, South Africa, and South Asia. Common names for the genus include glasswort, pickleweed, picklegrass, and marsh samphire; these common names are also used for some species not in "Salicornia". The main European species is often eaten, called marsh samphire in Britain, and the main North American species is occasionally sold in grocery stores or appears on restaurant menus, usually as <nowiki>'</nowiki>sea beans<nowiki>'</nowiki> or samphire greens or sea asparagus .
Document 13: Fockea edulis: Fockea edulis is a species of plant in the Apocynaceae family that is native to South Africa and Namibia. A common name is Hottentot bread due to the milky, somewhat sweetish flavour of the edible root which is sometimes gathered from the wild for local use. The plant's latex is said to be poisonous. In Afrikaans the plant is called Bergbaroe, Bergkambroo, Kambaroo, Kambroo, Kambro, or Hotnotswaatlemoen. In Khoi it is called !Koo, !Ku, or !Kuu. A semi-deciduous perennial caudiciform with fat, twisted grey roots, it grows in warmer drier areas, dry savannah and rockery. In the wild, the caudex is partially or totally buried and tends to grow faster this way up to 60 cm in diameter. Fockeas are dioecious, so a male plant and a female plant are needed to produce seeds. The flowers are whitish-green, not very showy but lightly scented, small (0.6-1.5 cm wide) vygie-like flowers surrounded by a large, thick, spider-like calyx. The flowers are pollinated by fruit flies. The plant produces grey-greenish pods. The thin vine branches may reach a length of up to 4 meters, and climb on any type of available support. The leaves are green, entire and oblong. Although it shows decreased activity in the January – April period, it never goes into complete dormancy and always carries some leaves. Plants cannot tolerate more than occasional light frosts with temperatures dropping as low as -2°C. This species is of easy cultivation and hardy when kept reasonably dry and watered only enough to keep the tuber from shriveling.
Document 14: Tree fern: The tree ferns are the ferns that grow with a trunk elevating the fronds above ground level. Most tree ferns are members of the "core tree ferns", belonging to the families Dicksoniaceae, Metaxyaceae, and Cibotiaceae in the order Cyatheales. In addition to those families, many ferns in other groups may be considered tree ferns, such as several ferns in the family Osmundaceae, which can achieve short trunks under a metre tall, and particularly ferns in the genus "Cibotium", which can grow ten metres tall. Fern species with short trunks in the genera "Blechnum, Calochleana, Cnemedaria, Culcita" (Europe's only tree fern), "Cystodium, Leptopteris, Lophosoria, Sadleria, Thyrsopteris" and "Todea" could also be considered tree ferns in a liberal interpretation of the term.
Document 15: Cyathea geluensis: Cyathea geluensis is a species of tree fern native to central and eastern New Guinea as well as the Louisiade Archipelago, where it grows in mossy forest. In New Guinea itself, plants grow at an altitude of 1000–2000 m, however they are present at lower elevations of 700–900 m on associated islands. The trunk of this tree fern is erect and may be 5 m tall or more. Fronds are bi- or tripinnate and 1-2.5 m long. They are usually about ten live fronds present in the crown at once. The stipe may be warty and/or have short spines as well as many scattered scales towards the base. These scales are pale to dark and have dull, fragile edges. Sori occur near the fertile pinnule midvein and are protected by pale, thin indusia. "C. geluensis" is a variable taxon and further study is needed to determine whether it does not in fact represent a species complex.
