中国苗木网,999miaomu.com

    小灌丛或矮树，15(－25)m，雌雄异体，主干高6(－12)dm，竖立或弯曲，具有凹槽，树冠呈倒圆锥形。树皮附有鳞片。鳞片内部呈淡紫色至紫褐色，外部呈淡白色至紫白色。枝条程度陈列或下垂。叶片长1-2.9cm，宽1－3mm，淡绿色，螺旋状陈列，表皮气孔带有乳突，亮黄绿色，叶子表皮细胞从横截面看大多比宽高。种子具2－4棱角，5－6.5mm。

    种子在晚夏-早秋成熟。生善于茂密的森林，小溪边，平整湿地，斜坡，深谷和峡谷。0-2200m。喜马拉雅红豆杉的叶子经常弯镰状，它的木头轻而巩固，但是轻易被加工，这使它大受木工的欢送，他们常用它来做新鲜奇特的工艺。由于这个，大棵的树常被乱砍伐，在少许地域，这一种红豆杉已然消逝。对这一种红豆杉在医药方面的开发，也已然要挟到了它的生活。 苗木网,999miaomu.com

    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.
