In German it is known as Eibe. Baccata is Latin for bearing berries. The word yew as it was originally used seems to refer to the colour brown.

The bark is thin, scaly brown, and comes off in small flakes aligned with the stem. The leaves are flat, dark green, 1–4 centimetres (1⁄2–1+1⁄2 in) long, 2–3 mm (3⁄32–1⁄8 in) broad, and arran…
Distribution and habitat
T. baccata is native to all countries of Europe, the Caucasus, and beyond from Turkey eastwards to northern Iran. Its range extends south to Morocco and Algeria in North Africa. A few populations are also present in the archipelagos of the Azores and Madeira. The limit of its northern Scandinavian distribution is its sensitivity to frost, with global warming predicted to allow its spread inland. It has been introduced elsewhere, including the United States.
Longevity
Taxus baccata can reach 400 to 600 years of age. Some specimens live longer but the age of yews is often overestimated. Ten yews in Britain are believed to predate the 10th century.
