Tsuga dumosa, commonly called the Himalayan hemlock or in Chinese, Yunnan tieshan (), is a species of conifer native to the eastern Himalayas.
 It occurs in parts of Nepal, India,(Bhutan), Burma, Vietnam, Tibet, and China.
 Within its native range the tree is used for construction as well as for furniture.
 In Europe and North America, it is occasionally encountered as an ornamental species and was first brought to the United Kingdom in 1838.
Taxus brevifolia, the Pacific yew or western yew, is a conifer native to the Pacific Northwest of North America.
 It ranges from southernmost Alaska south to central California, mostly in the Pacific Coast Ranges, but with isolated disjunct populations in southeast British Columbia (most notably occurring on Zuckerberg Island near Castlegar) and in north to central Idaho.
Pseudotsuga menziesii" var.
 "menziesii, also known as coast Douglas-fir, Oregon pine, or Douglas spruce, is an evergreen conifer native to western North America from west-central British Columbia, Canada southward to central California, United States.
 In Oregon and Washington its range is continuous from the Cascades crest west to the Pacific Coast Ranges and Pacific Ocean.
 In California, it is found in the Klamath and California Coast Ranges as far south as the Santa Lucia Mountains with a small stand as far south as the Purisima Hills, Santa Barbara County.
 In the Sierra Nevada it ranges as far south as the Yosemite region.
 It occurs from near sea level along the coast to 1800 m in the California Mountains.
 Further inland, coast Douglas-fir is replaced by Rocky Mountain or interior Douglas-fir ("P. menziesii" var.
 "glauca").
 Interior Douglas-fir intergrades with coast Douglas-fir in the Cascades of northern Washington and southern British Columbia.
Fitzroya is a monotypic genus in the cypress family.
 The single living species, Fitzroya cupressoides, is a tall, long-lived conifer native to the Andes mountains of southern Chile and Argentina, where it is an important member of the Valdivian temperate rain forests. Common names include alerce ("larch" in Spanish), lahuán (Spanish, from the Mapuche Native American name "lawal"), and Patagonian cypress.
 The genus was named in honour of Robert FitzRoy.
Tsuga sieboldii, also called the southern Japanese hemlock, or in Japanese, simply tsuga (栂), is a conifer native to the Japanese islands of Honshū, Kyūshū, Shikoku and Yakushima.
 In Europe and North America the tree is sometimes used as an ornamental and has been in cultivation since 1861.
Tsuga diversifolia, commonly known as the northern Japanese hemlock, or in Japanese, kometsuga (米栂), is a species of conifer native to the Japanese islands of Honshū, Kyūshū, and Shikoku.
 In Europe and North America, the species is sometimes employed as tree for the garden and has been in cultivation since 1861.
Pseudotsuga macrocarpa, commonly called the bigcone spruce or bigcone Douglas-fir, is an evergreen conifer native to the mountains of southern California, It is notable for having the largest (by far) cones in its "Pseudotsuga" genus, hence the name.
Decinnamoyltaxinine J is a taxane isolate derived from "Taxus brevifolia".
Keteleeria evelyniana (Evelyn keteleeria, , Vietnamese: Du sam) is a species of conifer native to southern China, Laos and Vietnam.
 It can become 40 m tall.
Pseudotsuga menziesii" var.
 "glauca, or Rocky Mountain Douglas-fir, is an evergreen conifer native to the interior mountainous regions of western North America, from central British Columbia and southwest Alberta in Canada southward through the United States to the far north of Mexico.
 The range is continuous in the northern Rocky Mountains south to eastern Washington, eastern Oregon, Idaho, western and south-central Montana and western Wyoming, but becomes discontinuous further south, confined to "sky islands" on the higher mountains in Utah, Colorado, Arizona and New Mexico, with only very isolated small populations in eastern Nevada, westernmost Texas, and northern Mexico.
 It occurs from 600 m altitude in the north of the range, up to 3,000 m, rarely 3,200 m, in the south.
 Further west towards the Pacific coast, it is replaced by the related coast Douglas-fir ("Pseudotsuga menziesii" var.
 "menziesii"), and to the south, it is replaced by Mexican Douglas-fir in high mountains as far south as Oaxaca.
 Some botanists have grouped Mexican Douglas-fir with "P. menziesii" var.
 "glauca", but genetic and morphological evidence suggest that Mexican populations should be considered a different variety.
