Cephalotaxus oliveri, the Oliver's plum yew, is a coniferous shrub or small tree in the family Taxaceae. It is native to China and possibly to Thailand, Laos, Vietnam and eastern India.
Shrubs or small trees up to 4 m tall. The bark is yellow to grayish brown and scaly. The leafy branchlets are oblong-elliptic in outline. Leaves are borne at 55-70° to branchlet axis. The pollen-cone is borne on the lower side and toward the distal end of terminal branchlets. The buds develop before the subtending leaves expand. Seeds cones are solitary. Seeds are obovoid, ovoid, or almost globose. Pollination occurs Mar-Apr while seeds mature from Aug-Oct. [2]
Cephalotaxus oliveri occurs in subtropical evergreen and deciduous broad-leaved forests, coniferous and mixed forests, at altitudes between 300 and 1,800 meters above sea level. It is an understorey shrub, occurring in the shrub layer mixed with several genera of angiosperms such as Rhododendron , Camellia , Cotoneaster , Deutzia , Lonicera , Berberis , Buddleia , Euonymus , Hydrangea , Prunus and other species. [1]
This species is exploited for its bark, twigs, roots and seeds, which contain anti-carcinogenic alkaloids, for medicinal purpose. It is also cultivated as an ornamental shrub both in and outside China. [1]
This species has a wide range and a large population, but it has experienced population reduction of more than 30% over the last 90–100 years due to exploitation of the plant for medicinal purposes and the loss of habitat due to deforestation by logging and agricultural expansion. The reduction is likely to continue, so this species is listed as Vulnerable based on the past declines. [1]
Dacrydium cupressinum, commonly known as rimu, is a large evergreen coniferous tree endemic to the forests of New Zealand. It is a member of the southern conifer group, the podocarps.
Taxaceae, commonly called the yew family, is a coniferous family which includes six extant and two extinct genera, and about 30 species of plants, or in older interpretations three genera and 7 to 12 species.
Prumnopitys taxifolia, the mataī or black pine, is an endemic New Zealand coniferous tree that grows on the North Island and South Island. It also occurs on Stewart Island/Rakiura but is uncommon there.
Pinus koraiensis is a species of pine known commonly as the Korean pine. It is a relic species of the Tertiary, identified as a rare tree species by United Nations. It is native to eastern Asia: Korea, northeastern China, Mongolia, the temperate rainforests of the Russian Far East, and central Japan. In the north of its range, it grows at moderate elevations, typically 600 to 900 metres, whereas further south, it is a mountain tree, growing at 2,000 to 2,600 m elevation in Japan. Other common names include Chinese pinenut. The ancient woodland of P. koraiensis on the earth is about 50 million hectares, and China has about 30 million hectares, accounting for 60%. It is a second-class national key protected plant in China. P. koraiensis is a tree species with high economic and ecological value. The official name in Chinese is "红松 hóng sōng/red pine", because almost every part of it is related to red.
Nageia is a genus of conifers belonging to the podocarp family Podocarpaceae. Nageia includes evergreen shrubs and trees, from one to 54 meters in height. A 2009 treatment of the genus recognized five species. Some authors consider Nageia formosensis to be a separate species from Nageia nagi, thus recognizing six species. The podocarp genera have been reshuffled by various botanists. Most recently, several species formerly classed as Nageia were moved to the new genus Retrophyllum, while Nageia falcata and Nageia mannii were moved to the new genus Afrocarpus.
Podocarpus macrophyllus is a conifer in the genus Podocarpus, family Podocarpaceae. It is the northernmost species of the genus, native to southern Japan and southern and eastern China. Common names in English include yew plum pine, Buddhist pine, fern pine and Japanese yew. Kusamaki (クサマキ) and inumaki (犬槇) are Japanese names for this tree. In China, it is known as luóhàn sōng (羅漢松), which literally means "arhat pine".
Pseudotaxus chienii, the whiteberry yew, is a species of plant in the yew family, Taxaceae. It is the sole species in the genus Pseudotaxus, but closely related to the other yews in the genus Taxus. It is endemic to southern China, occurring in northern Guangdong, northern Guangxi, Hunan, Southwest Jiangxi and southern Zhejiang.
Taxus brevifolia, the Pacific yew or western yew, is a species of tree in the yew family Taxaceae native to the Pacific Northwest of North America. It is a small evergreen conifer, thriving in moisture and otherwise tending to take the form of a shrub.
Diselma archeri is a species of plant of the family Cupressaceae and the sole species in the genus Diselma. It is endemic to the alpine regions of Tasmania's southwest and Central Highlands, on the western coast ranges and Lake St. Clair. It is a monotypic genus restricted to high altitude rainforest and moist alpine heathland. Its distribution mirrors very closely that of other endemic Tasmanian conifers Microcachrys tetragona and Pherosphaera hookeriana.
Keteleeria davidiana is a coniferous evergreen tree native to Taiwan and southeast China, in the provinces of Gansu, Guangxi, Guizhou, Hubei, Hunan, Shaanxi, Sichuan, and Yunnan. It also occurs in the very northern part of Vietnam. The tree is restricted to hills, mountains, and valleys at elevations of 200–1500 m. Generally, it grows in regions with a more continental climate than the other two Keteleeria species.
Juniperus squamata, the flaky juniper, or Himalayan juniper is a species of coniferous shrub in the cypress family Cupressaceae, native to the Himalayas and China.
Abies guatemalensis, the Guatemalan fir or pinabete, is an evergreen tree native to Central America and is the southernmost member of the genus Abies being spread to the south lower than 14° N. Its range is from southern Mexico in the north to Honduras and El Salvador in the south. It is a warm-loving and moisture-loving tree of the tropical mountain coniferous and mixed cloud forests of these countries. The Guatemalan fir is an almost completely non-frost-resistant tree. Due to logging and loss of habitat, the tree is considered threatened and is protected in CITES Appendix I.
Taxus wallichiana, the Himalayan yew, is a species of yew, native to the Himalaya and parts of south-east Asia. The species has a variety of uses in traditional medicine. It is currently classified as endangered by the IUCN.
Cephalotaxus hainanensis is a species of conifer known by the common name Hainan plum-yew. It is native to southern China, southeastern Tibet, and Myanmar, Thailand, and Vietnam in northern Indochina.
Taxus floridana, the Florida yew, is a species of yew, endemic to a small area of under 10 km² on the eastern side of the Apalachicola River in mesophytic forests of northern Florida at altitudes of 15–40 m. It is listed as critically endangered. It is protected in reserves at the Torreya State Park and at the Nature Conservancy's Apalachicola Bluffs and Ravines Preserve, and has legal protection under the United States and Florida Endangered Species laws.
Tsuga chinensis, commonly referred to as the Taiwan or Chinese hemlock, or in Chinese as tieshan, is a coniferous tree species native to China, Taiwan, Tibet and Vietnam. The tree is quite variable and has many recognised varieties, though some are also maintained to be separate species by certain authorities. The tree was recently discovered in the mountains of northern Vietnam, making that the southernmost extension of its range.
Cephalotaxus wilsoniana is a species of coniferous tree in the yew family, Taxaceae. Its common names include Taiwan plum yew, Taiwan cow's-tail pine, and Wilson plum yew. It is endemic to Taiwan, scattered in montane forests at altitudes of 1400-2700 meters. Cephalotaxus wilsoniana is mostly dioecious, because it's scattered with broad-leaved trees, the fecundity is not strong. In addition, the seed maturity period is very long. Germination and growth are also slow. Therefore, Cephalotaxus wilsoniana is not a common tree species in Taiwan.
Cephalotaxus fortunei, commonly called the Chinese plum-yew, Fortune's yew plum, simply plum yew, Chinese cowtail pine or in Chinese as san jian shan, is a coniferous shrub or small tree in the family Taxaceae. It is native to northern Burma and China, but is sometimes grown in western gardens where it has been in cultivation since 1848.

Nageia wallichiana is a species of conifer in the family Podocarpaceae. It is a tree 10–54 m high, found in Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam. Nageia wallichiana is the most widely distributed species among the seven species in the genus Nageia. If the land areas of China and Japan are excluded, its distribution nearly coincides with that of the genus and includes both the western outliers in India and the easternmost part on Normanby Island. It is one of the most extensive conifer ranges recognized and is similar to Dacrycarpus imbricatus and Podocarpus neriifolius.
