Yew | | Name : | Yew | | Botanical : | Taxus baccata | | Family : | Taxaceae and Coniferae | | Habitat : | Europe, North Africa, Western Asia. | | Description : | A tree 40 to 50 feet high, forming with age a very stout trunk covered with red-brown, peeling bark and topped with a rounded or wide-spreading head of branches; leaves spirally attached to twigs, but by twisting of the stalks brought more or less into two opposed ranks, dark, glossy, almost black-green above, grey, pale-green or yellowish beneath, 1/2 to 1 1/2 inches long, 1/16 to 1/12 inch wide. Flowers unisexual, with the sexes invariably on different trees, produced in spring from the leaf axils of the preceding summer's twigs. Male, a globose cluster of stamens; female, an ovule surrounded by small bracts, the so-called fruit bright red, sometimes yellow, juicy and encloses the seed.
No tree is more associated with the history and legends of Great Britain than the Yew. Before Christianity was introduced it was a sacred tree favoured by the Druids, who built their temples near these trees - a custom followed by the early Christians. The association of the tree with places of worship still prevails.
Many cases of poisoning amongst cattle have resulted from eating parts of the Yew. | | Constituents : | The fruit and seeds seem to be the most poisonous parts of the tree. An alkaloid taxine has been obtained from the seeds; this is a poisonous, white, crystalline powder, only slightly soluble in water; another principle, Milossin, has also been found. |
