Comments:
Pacific Yew is a small, somewhat rare understory tree found in forests of the Pacific Northwest. It is the only native in the yew family (Taxaceae). The needles lie flat on opposite sides of the twig and are lighter green below. The seeds are partly enclosed in a modified cone scale that develops into a small, red berry-like fruit, called an "aril." Birds eat the arils and disperse the seeds, but these seeds, are quite poisonous to humans. The distinctive bark is a patchwork of peeling papery brown or gray scales over a smooth, red –brown inner layer. Pacific Yew recently became important when scientists found that the taxol rendered from the bark can be used to treat cancer. Today taxol is synthesized from the needles and bark of other cultivated yews.
