Yews are small coniferous trees or shrubs in the genus Taxus in the yew family Taxaceae. They are relatively slow growing and can be very long-lived, and reach heights of 1-40 m, with trunk diameters of up to 4 m. They have reddish bark, lanceolate, flat, dark-green leaves 1-4 cm long and 2-3 mm broad, arranged spirally on the stem, but with the leaf bases twisted to align the leaves in two flat rows either side of the stem.

European Yew cone (detail)
European Yew cone (detail)

The seed cones are highly modified, each cone containing a single seed 4-7 mm long partly surrounded by a modified scale which develops into a soft, bright red berry-like structure called an aril, 8-15 mm long and wide and open at the end. The arils are mature 6-9 months after pollination, and with the seed contained are eaten by thrushes, waxwings and other birds, which disperse the hard seeds undamaged in their droppings; maturation of the arils is spread over 2-3 months, increasing the chances of successful seed dispersal. The male cones are globose, 3-6 mm diameter, and shed their pollen in early spring. Yews are mostly dioecious, but occasional individuals can be variably monoecious, or change sex with time.

The most distinct is the Sumatran Yew (T. sumatrana, native from Sumatra and Celebes north to southernmost China), distinguished by its sparse, sickle-shaped yellow-green leaves. The Mexican Yew (T. globosa, native to eastern Mexico south to Honduras) is also relatively distinct with foliage intermediate between Sumatran Yew and the other species.

All species of yew contain the highly poisonous alkaloid taxine, with some variation in the exact formula of the alkaloid between the species. All parts of the tree except the arils contain the alkaloid. The arils are edible and sweet, but the seed is dangerously poisonous; unlike birds, the human stomach can break down the seed coat and release the taxine into the body. This can have fatal results if yew 'berries' are eaten without removing the seeds first. Grazing animals, particularly cattle and horses, are also sometimes found dead near yew trees after eating the leaves, though deer are able to break down the poisons and will eat yew foliage freely. In the wild, deer browsing of yews is often so extensive that wild yew trees are commonly restricted to cliffs and other steep slopes inaccessible to deer. The foliage is also eaten by the larvae of some Lepidopteran insects including Willow Beauty. The skull and crossbones symbol traditionally used to label a poisonous substance. ...

Uses and traditions

Yew wood is reddish brown (with whiter sapwood), and is very hard. It was traditionally used to make bows, especially the longbow. Ötzi, the Copper age mummy found in 1991 in the Austrian alps, carried an unfinished longbow made of yew wood. Consequently, it is not surprising that, in Norse mythology, the god of the bow, Ullr's abode had the name Ydalir (Yew dales). Most longbow wood used in northern Europe was imported from Iberia, where climatic conditions are better for growing the knot-free yew wood required.

The Pacific Yew Taxus brevifolia, native to the Pacific Northwest of North America, is the source of paclitaxel, a drug with apparent anti-cancer activity. Over-harvesting of the Pacific Yew for this drug has resulted in it becoming an endangered species, though the drug is now produced semi-synthetically from cultivated yews, without the need to further endanger the wild populations.
