The Douglas fir is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir, Rocky Mountain Douglas-fir and Mexican Douglas-fir.
Wollemia is a genus of coniferous trees in the family Araucariaceae, endemic to Australia. It represents only one of three living genera in the family, alongside Araucaria and Agathis. The genus only has a single known species, Wollemia nobilis, which was discovered in 1994 in a temperate rainforest wilderness area of the Wollemi National Park in New South Wales. It was growing in a remote series of narrow, steep-sided, sandstone gorges 150 km (93 mi) north-west of Sydney. The genus is named after the National Park.
Metasequoia glyptostroboides, the dawn redwood, is a fast-growing, endangered deciduous conifer. It is the sole living species of the genus Metasequoia, one of three genera in the subfamily Sequoioideae of the family Cupressaceae. It now survives in the wild only in wet lower slopes and montane river and stream valleys in the border region of Hubei and Hunan provinces and Chongqing municipality in south-central China, notably in Lichuan county in Hubei. Although the shortest of the redwoods, it can grow to 167 ft (51 m) in height.
Tsuga is a genus of conifers in the subfamily Abietoideae of Pinaceae, the pine family. The English-language common name "hemlock" arose from a perceived similarity in the smell of its crushed foliage to that of the unrelated plant poison hemlock. Unlike the latter, Tsuga species are not poisonous.
Persicaria maculosa is an annual plant in the buckwheat family, Polygonaceae. Common names include lady's thumb, spotted lady's thumb, Jesusplant, and redshank. It is widespread across Eurasia from Iceland south to Portugal and east to Japan. It is also present as an introduced and invasive species in North America, where it was first noted in the Great Lakes region in 1843 and has now spread through most of the continent.
Taiwania, with the single living species Taiwania cryptomerioides, is a large coniferous tree in the cypress family Cupressaceae.
Hesperocyparis arizonica, the Arizona cypress, is a North American species of tree in the cypress family Cupressaceae, native to the southwestern United States and Mexico. Populations may be scattered rather than in large, dense stands.
Papuacedrus papuana is a species in the conifer family Cupressaceae, the sole species in the genus Papuacedrus. Some botanists do not consider this species as forming a distinct genus, but include it in the related genus Libocedrus. It is native to New Guinea and to the Indonesian Province of Maluku.
Actinostrobus pyramidalis, commonly known as swamp cypress, Swan River cypress and King George's cypress pine, is a species of coniferous tree in the Cupressaceae. Like the other species in the genus Actinostrobus, it is endemic to southwestern Western Australia.
Larix kaempferi, the Japanese larch or karamatsu in Japanese, is a species of larch native to Japan, in the mountains of Chūbu and Kantō regions in central Honshū.
Jubaea is a genus of palms with one species, Jubaea chilensis, commonly known in English as the Chilean wine palm or Chile cocopalm, and palma chilena in Spanish. It is native to southwestern South America and is endemic to a small area of central Chile between 32°S and 35°S in southern Coquimbo, Valparaíso, Santiago, O'Higgins, and northern Maule regions.
Hesperocyparis lusitanica, the Mexican cypress, cedar-of-Goa or Goa cedar, is a species of cypress native to Mexico and Central America. It has also been introduced to Belize, Costa Rica and Nicaragua, growing at 1,200–3,000 metres (3,900–9,800 ft) altitude.
Corypha umbraculifera, the talipot palm, is a species of palm native to eastern and southern India and Sri Lanka. It is also grown in Cambodia, Myanmar, Thailand and the Andaman Islands. It is one of the five accepted species in the genus Corypha. It is a flowering plant with the largest inflorescence in the world. It lives up to 60 years before bearing flowers and fruits. It dies shortly after.
Ulmus castaneifoliaHemsley, the chestnut-leafed elm or multinerved elm, is a small deciduous tree found across much of China in broadleaved forests at elevations of 500–1,600 metres (1,600–5,200 ft).
Quercus canariensis, the Algerian oak, Mirbeck's oak or zean oak, is an oak native to southern Portugal, Spain, Tunisia, Algeria and Morocco. Despite the scientific name, it does not occur naturally today in the Canary Islands, though it may have in the past. It is placed in section Quercus.
Abies chensiensis, the Shensi fir, is a fir native to Gansu, Hubei, Sichuan, Tibet, Yunnan in China, and Arunachal Pradesh in India. It was first described by Philippe Édouard Léon Van Tieghem in 1892.
Saribus jeanneneyi is a very rare species of palm tree in the genus Saribus. It is endemic to southern New Caledonia, where only one mature specimen, surrounded by a few seedlings, survived in its native habitat as of 1997. The cause of its rarity in the wild is because its meristem is edible.
Opisthiolepis is a monotypic genus of trees in the macadamia family Proteaceae. The sole species is Opisthiolepis heterophylla, commonly known as blush silky oak, pink silky oak, brown silky oak or drunk rabbit. It was first described in 1952 and is endemic to a small part of northeastern Queensland, Australia.
The Laricoideae are a subfamily of the Pinaceae, a Pinophyta division family. They take their name from the genus Larix (larches), which contains inside most of the species of the group and is one of only two deciduous genera of the pines complex. Ecologically important trees, the Laricoideae form pure or mixed forest associations often dominant in the ecosystems in which they are present, thanks also to their biological adaptations to natural disturbances, to reproductive strategies put in place and high average longevity of the individuals. Currently are assigned to this subfamily three genera and its members can be found only in Northern Hemisphere. The various species live for the most part in temperate or cold climates and are the more northerly conifers; some constitute an important source of timber and non-timber forest products.
