    種子在晚夏-早秋成熟。生善于茂密的森林，小溪邊，平整濕地，斜坡，深谷和峽谷。0-2200m。喜馬拉雅紅豆杉的葉子經常彎鐮狀，它的木頭輕而鞏固，但是輕易被加工，這使它大受木工的歡送，他們常用它來做新鮮奇特的工藝。由于這個，大棵的樹常被亂砍伐，在少許地域，這一種紅豆杉已然消逝。對這一種紅豆杉在醫藥方面的開發，也已然要挾到了它的生活。 苗木網,www.jin1234.com

    Shrubs or small trees to 15(－25)m, dioecious; trunk to 6(－12)dm diam., straight to contorted,fluted; crown open-conical. Bark scaly, outer scales purplish to purplish brown, inner ones reddish to reddish purple. Branches horizontal to drooping. Leaves 1-2.9cm × 1－3mm, pale green abaxially, cuticular papillae present along stomatal bands,shiny yellow-green adaxially, epidermal cells as viewed in cross section of leaf mostly taller than wide. Seed oviod, 2-4-angled, 5-6.5mm.

    Seeds maturing late summer-fall. Open to dense forests, along streams, moist flats, slopes, deep ravines, and coves; 0-2200 m. The leaves are usually somewhat falcate. The wood is hard and durable, yet easily worked, making it popular for construction of novelty items by local woodworkers. Because of this, large trees are unscrupulously poached; in some areas the species has been nearly extirpated. Exploitation of the species for medicinal purposes is further threatening it. 999苗木網,www.jin1234.com
