Cephalotaxus wilsoniana
Template:Short description Template:Speciesbox
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,[1] and Wilson's plum yew. The taxon name, Cephalotaxus wilsoniana, is disputed by many authorities: A Chinese online database gives its revised name as Cephalotaxus sinensis var. wilsoniana,[2] while Plants of the World Online and other authorities consider it to be the species Cephalotaxus harringtonii.[3][4] (In synonymising this name with C. harringtonia, Plants of the World online cites several authorities.)[3][5][6][7][8]
Description
It is endemic to Taiwan,[4] scattered in montane forests at altitudes of Template:Cvt.[9] As Cephalotaxus wilsoniana is dioecious, and grows scattered amongst broad-leaved trees, the fecundity is not strong. In addition, the seed maturity period is very long. As germination and growth are also slow, Cephalotaxus wilsoniana is not commonly found.
This conifer grows up to Template:Cvt tall with drooping branches and reddish-brown flaky bark. It grows in scattered populations in the woodlands of Taiwan. It is sometimes cultivated in local gardens.[1]
The wood of Cephalotaxus wilsoniana is light yellowish brown with dense structure and excellent quality, which can be used for construction, furniture, agricultural appliances. A variety of plant alkaloids can be extracted from leaves, branches, roots and seeds.[9]
