The Himalayan Yew is a species of yew, native to the Himalaya from Afghanistan east to western Yunnan in southwestern China, at altitudes from 2,000–3,500 m.〔Farjon, A. (1998). ''World Checklist and Bibliography of Conifers''. Royal Botanic Gardens, Kew ISBN 1-900347-54-7.〕〔Rushforth, K. (1987). ''Conifers''. Helm ISBN 0-7470-2801-X.〕 The species is listed in CITES appendix II. ==Growth== It is a medium-sized evergreen coniferous tree growing to 20 m tall, similar to ''Taxus baccata'' and sometimes treated as a subspecies of it. The shoots are green at first, becoming brown after three or four years. The leaves are thin, flat, slightly falcate (sickle-shaped), 1.5–2.7 cm long and 2 mm broad, with a softly mucronate apex; they are arranged spirally on the shoots but twisted at the base to appear in two horizontal ranks on all except for erect lead shoots. It is dioecious, with the male and female cones on separate plants; the seed cone is highly modified, berry-like, with a single scale developing into a soft, juicy red aril 1 cm diameter, containing a single dark brown seed 7 mm long. The pollen cones are globose, 4 mm diameter, produced on the undersides of the shoots in early spring.〔
