Question: Are both Oxypetalum and Metasequoia types of trees?

full_context: Document 1: Oplopanax: Oplopanax is a small genus of flowering plants in the family Araliaceae, consisting of three species of deciduous shrubs, native to western North America and northeastern Asia. "Oplopanax" is closely related to the Asian genus "Fatsia".
Document 2: Graptopetalum: Graptopetalum (leatherpetal) is a plant genus of the family "Crassulaceae". They are perennial succulent plants and native to Mexico and Arizona. They grow usually in a rosette. There are around 19 species in this genus.
Document 3: Metasequoia: Metasequoia (dawn redwood) is a fast-growing, deciduous tree, and the sole living species, "Metasequoia glyptostroboides", is one of three species of conifers known as redwoods. It is native to Lichuan county in Hubei province, China. Although the least tall of the redwoods, it grows to at least 200 feet (60 meters) in height. Local villagers refer to the original tree from which most others derive as "Shui-sa", or "water fir", which is part of a local shrine. Since its rediscovery in 1944, the dawn redwood has become a popular ornamental.
Document 4: Cunninghamia: Cunninghamia is a genus of one or two living species of evergreen coniferous trees in the cypress family Cupressaceae. They are native to China, northern Vietnam and Laos, and perhaps also Cambodia. They may reach 50 m in height. In vernacular use, it is most often known as "Cunninghamia", but is also sometimes called "China-fir" (though it is not a fir). The genus name "Cunninghamia" honours Dr. James Cunningham, a British doctor who introduced this species into cultivation in 1702 and botanist Allan Cunningham.
Document 5: Sequoia (genus): Sequoia is a genus of redwood coniferous trees in the subfamily Sequoioideae of the family Cupressaceae. The only extant species of the genus is "Sequoia sempervirens" in the Northern California coastal forests ecoregion of Northern California and Southwestern Oregon in the United States. The two other genera, "Sequoiadendron" and "Metasequoia", in the subfamily Sequoioideae are closely related to "Sequoia". It includes the largest trees in the world.
Document 6: Red Creek fir: The Red Creek Fir is a Douglas fir tree, at least 1000 years old, standing near Port Renfrew on Vancouver Island in British Columbia, Canada. With its diameter of 4.2 meters (13.8 feet) and height of 73.8 meters (242 feet), it is the largest Douglas fir in the world. Note it is not the tallest in Canada (MacMillan Provincial Park houses a specimen 10 meters (33 feet) taller) but it does contain more wood than any other known Douglas fir.
Document 7: 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 8: Thevetia: Thevetia is a genus of flowering plants in the dogbane family, Apocynaceae, first described for modern science as a genus in 1758. It is native to Mexico, Central America, South America, and Cuba. The taxonomy of the genus is controversial, with some authors including "Cascabela" within "Thevetia", while others accept the two genera as separate.
Document 9: Oxystylis: Oxystylis is a monotypic genus of flowering plants currently considered a part of the cleome family containing the single species Oxystylis lutea, which is known by the common name spiny caper. It is native to the Mojave Desert straddling the border between California and Nevada. It grows in rocky and sandy desert habitat, often on alkaline soils. This is an annual herb producing an erect, branching stem which may reach 1.5 meters in height. The leaf is made up of three thick, firm leaflets 2 to 6 centimeters long, borne on a stout, straight petiole. The inflorescence is a dense head of flowers clustered about the stem at the leaf axils, each flower with four small yellow petals. The fruit is a small white or purple nutlet bearing the spine-like remnant of the flower receptacle.
Document 10: Oxypetalum: Oxypetalum is a genus of flowering plants in the Apocynaceae family, first described with this name in 1810. The genus is native to South America.
Document 11: Hypoxis: Hypoxis is a genus of flowering plants belonging to the family Hypoxidaceae. The genus has an "almost cosmopolitan" distribution, occurring in Africa, the Americas, Asia, and Australia. Europe lacks native species. Most species are in the Southern Hemisphere, especially in southern Africa. Common names for the genus include star-grass, star lily, yellow stars, African potato, and stars. The genus is the largest of the Hypoxidaceae family and has its centre of variation in South Africa, where it occurs in open undisturbed grasslands. The name "Hypoxis" was taken over by Linnaeus in 1759 from a name coined by Paul Reneaulme in 1611 for a superficially similar species of "Gagea" and meaning "a little sour", referring to the taste of that plant's leaves.
Document 12: Thuja plicata: Thuja plicata, commonly called western or Pacific redcedar, giant or western arborvitae, giant cedar, or shinglewood, is a species of "Thuja", an evergreen coniferous tree in the cypress family Cupressaceae native to western North America. It is not a true cedar of the genus "Cedrus".
Document 13: Sequoiadendron giganteum: Sequoiadendron giganteum (giant sequoia; also known as giant redwood, Sierra redwood, Sierran redwood, Wellingtonia or simply Big Treea nickname used by John Muir) is the sole living species in the genus "Sequoiadendron", and one of three species of coniferous trees known as redwoods, classified in the family Cupressaceae in the subfamily Sequoioideae, together with "Sequoia sempervirens" (coast redwood) and "Metasequoia glyptostroboides" (dawn redwood). The common use of the name "sequoia" generally refers to "Sequoiadendron giganteum", which occurs naturally only in groves on the western slopes of the Sierra Nevada Mountains of California.
Document 14: Aphelandra: Aphelandra is a genus of about 170 species of flowering plants in the family Acanthaceae, native to tropical regions of the Americas.
Document 15: Douglas fir: Pseudotsuga menziesii, commonly known as Douglas fir or Douglas-fir, is an evergreen conifer species native to western North America. One variety, the coast Douglas fir, grows along the Pacific Ocean from central British Columbia south to central California. A second variety, the Rocky Mountain Douglas fir, grows in the Rocky Mountains from British Columbia south to Mexico. The tree is dominant in western Washington. It is extensively used for timber, worldwide.
