Cephalotaxus
''Cephalotaxus'', commonly called plum yew or cowtail pine, is a genus of conifers comprising 11 species, treated in either the Cephalotaxaceae, or in the Taxaceae when that family is considered in a broad sense. The genus is endemic to eastern Asia, though fossil evidence shows it had a wider Northern Hemisphere distribution in the past. The species are evergreen shrubs and small trees reaching (rarely to ) tall. Taxonomy Molecular studies place ''Cephalotaxus'' as the most basal member of the Taxaceae, having a very ancient divergence from them during the late Triassic. Description The leaves are spirally arranged on the shoots, but twisted at the base to lie in two flat ranks (except on erect leading shoots); they are linear, long and broad, soft in texture, with a blunt tip; this helps distinguish them from the related genus ''Torreya'', which has spine-tipped leaves. The species can be either monoecious or dioecious; when monoecious, the male and female cones are often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxaceae
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. Description They are many-branched, small trees and shrubs. The leaves are evergreen, spirally arranged, often twisted at the base to appear 2-ranked. They are linear to lanceolate, and have pale green or white stomatal bands on the undersides. The plants are dioecious, or rarely monoecious. The catkin like male cones are long, and shed pollen in the early spring. They are sometimes externally only slightly differentiated from the branches. The fertile bracts have 2-8 pollen sacs. The female 'cones' are highly reduced. Only the upper or uppermost bracts are fertile and bear one or rarely two seeds. The ovule usually exceeds the scale, although ovules are sometimes rarely enclosed by it. They may be found on the ends of branches or on the branches. They may grow sin ...

Cephalotaxus Harringtonii
''Cephalotaxus harringtonia'', commonly known as Japanese plum-yew, Harrington's cephalotaxus, or cowtail pine, is a coniferous bush or small tree in the family Taxaceae. It is native to Japan, but is occasionally utilised in western gardens and several cultivars exist for these purposes. Japanese plum yew has been in cultivation in Europe since 1829, and many modern horticulturists are familiar with this Japanese species, named in honor of Charles Stanhope, 4th Earl of Harrington, one of the first to grow the plant in a European garden, at Elvaston. Description New shoots of ''C. harringtonii'' remain green for three years after forming and have ribs at the leaf bases. The buds are green in colour, globular in shape and very small at only 1 mm in length. There is one rank of leaves present on either side of the shoot, and these rise up above it and curve slightly inwards, forming a narrow V-shape somewhat akin to a dove's wings. The ranks are often vertical, but can be more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cephalotaxus Wilsoniana
''Cephalotaxus wilsoniana'' is a species of pinophyta, coniferous tree in the yew family, Taxaceae. Its common names include Taiwan plum yew, Taiwan cow's-tail pine,''Cephalotaxus wilsoniana''. The Gymnosperm Database. and Wilson plum yew. It is endemism, 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. This taxon is sometimes considered to be a variety of ''Cephalotaxus harringtonii''.

Cephalotaxus Fortunei
''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.

Description ''Cephalotaxus fortunei'' is a shrub or small tree growing to as high as 20 m with a diameter at breast height of about 20 cm. They are usually multi-stemmed with an open and loosely rounded crown. In cultivation they tend to grow on a single stem that is often leaning and bare towards the bottom, but with dense foliage on the upper half. They have reddish brown bark that appears purplish in places with rough square scales and long shreds peeling off. The new shoots remain green for three years after emerging and are ribbed. The branches are slightly pendulous, while the branchlets are obovate, obtriangular or almost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cephalotaxus Hainanensis
''Cephalotaxus hainanensis'' is a species of pinophyta, conifer known by the common name Hainan plum-yew. It is endemism, endemic to the island of Hainan in southern China. It is possibly a synonym of ''Cephalotaxus mannii''. This species grows in warmer temperate and subtropical rainforest habitat. When mature it is a tree 10 to 20 meters tall. It is sometimes a Dominance (ecology), dominant species in the local ecosystem. ''C. hainanensis'' is suggested to have antileukemia activity, and is widely used as an herbal remedy in China. Exploitation of the bark and leaves is a potential threat to this species. Logging has historically been a cause of its decline, but as logging is no longer allowed on Hainan, much of the pressure is currently from illegal harvesting for Chinese remedies.
