Platycladus is a monotypic genus of evergreen coniferous trees in the cypress family Cupressaceae, containing only one species, Platycladus orientalis, also known as Chinese thuja, Oriental arborvitae, Chinese arborvitae, biota or Oriental thuja. It is native to northeastern parts of East Asia and North Asia, but is also now naturalised as an introduced species in other regions of the Asian continent.

The Dryopteridaceae are a family of leptosporangiate ferns in the order Polypodiales. They are known colloquially as the wood ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae. Alternatively, it may be treated as the subfamily Dryopteridoideae of a very broadly defined family Polypodiaceae sensu lato. The family contains about 1700 species and has a cosmopolitan distribution. Species may be terrestrial, epipetric, hemiepiphytic, or epiphytic. Many are cultivated as ornamental plants. The largest genera are

Colophospermum mopane, commonly called mopane, mopani, butterfly tree, turpentine tree, or balsam tree, is a tree in the legume family (Fabaceae), that grows in hot, dry, low-lying areas, 200 to 1,200 metres (660 to 3,940 ft) in elevation, in parts of Southern Africa. The tree only occurs in Africa and is the only species in genus Colophospermum. Its distinctive butterfly-shaped (bifoliate) leaf and thin kidney-shaped/nearly semi-circular seed pod make it easy to identify. Though hard and dense and difficult to work with, it is valued timber in all sorts of construction due to its termite

Woodsiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is placed in the suborder Aspleniineae. The family can also be treated as the subfamily Woodsioideae of a very broadly defined family Aspleniaceae sensu lato. In PPG I, the family contained only one genus, Woodsia. In 2020, Physematium was split off from Woodsia on the basis of molecular phylogenetic evidence. As of June 2023, Plants of the World Online continued to treat Physematium as a synonym of Woodsia.

Paulowniaceae are a family of flowering plants within the Lamiales. They are a monophyletic family of trees with currently 12 species in 3 genera. They were formerly placed within Scrophulariaceae sensu lato, or as a segregate of the Bignoniaceae. The Paulowniaceae are now resolved as a distinct separate family consisting of the genera Paulownia, Shiuyinghua and Wightia. They are deciduous trees with large heart shaped leaves and long panicles of white-purple to lavender flowers native to eastern Asia. The most widely distributed and recognized species is Paulownia tomentosa with common names

Araucaria biramulata, the biramule araucaria, or piggyback araucaria, is a species of conifer in the family Araucariaceae. It is found only in New Caledonia on the main island of Grande Terre. Araucaria biramulata is a medium-large tree reaching 30 meters in height. As with several other endemic New Caledonian araucaria species, it is threatened by habitat loss with a fragmented wild population of less than 10,000 mature trees, and ongoing decline in remaining populations, with the main threats being forest fires and mining activities. Piggyback araucaria gets its common name from the unusual

Araucaria humboldtensis, or Humboldt's araucaria, is a species of conifer in the family Araucariaceae. It is found only in New Caledonia. It is threatened by habitat loss, as even though the remaining wild populations are located within protected park areas, an increased frequency of forest fires in recent years has led to continued degradation of habitat and increased dieback of mature trees. Araucaria humboldtensis is one of the smaller trees in its family, ranging from 6–15 m in height, with a distinct flattened crown in mature specimens. It is found in the wild only in three remnant

Araucaria bernieri, commonly known as Bernier's columnar araucaria, is a species of conifer in the family Araucariaceae. It is found only in New Caledonia at elevations below 700 meters, mainly in the southern part of the main island. It is a large tree reaching 40–50 meters in height, though specimens growing on poorer soil tend to be dwarfed. It is threatened by habitat loss with a wild population of less than 10,000 mature trees, and ongoing decline in remaining populations.

Polaskia (named after American amateur Charles Polaski) is a genus of tree-like cacti reaching 4–5 m high, comprising 2 species. Both present primitive characteristics, but Polaskia chichipe is nearer to Myrtillocactus while Polaskia chende is nearer to Stenocereus. The genus is found in the Mexican states of Puebla and Oaxaca.

Encephalartos lebomboensis is a species of cycad in the family Zamiaceae. Native to the Lebombo Mountains of South Africa, the species was first described in 1949 by the South African botanist Inez Verdoorn.

Geoffroea decorticans, the chañar, kumbaru, or Chilean palo verde (green wood), is a small deciduous tree, up to 8 meters (25 ft) tall that inhabits most arid forests (montes or espinales) of southern South America. The chañar is cold and drought deciduous; it loses its leaves in winter, and possibly in summer if conditions get too dry. It is natural to Bolivia, Chile, Argentina, also present in Paraguay and southern Peru. It is a very characteristic tree in local culture and folk because of its vivid visual presence, propagation, and ancient ethnomedical uses.
