  根状茎短,不明显;根稍粗厚,粗约1-2毫米。叶形变化较大,长条形、条状披针形至近披针形,长8-60厘米,宽0.6-2(-5)厘米,基部有时收狭成柄状。花葶单个,通常比叶长;花白色,单生或2-3朵簇生,通常排成疏离的总状花序,较少具侧枝而成圆锥花序;花梗长约1厘米,关节通常位于近中部或上部;花被片长10-13毫米;雄蕊稍短于花被片;花药通常长约为花丝的一倍,较少近等长。蒴果三棱状,一般倒卵形,较少近球形,长约6-9毫米,每室具6-9颗种子。花果期7-9月。
  产西藏南部(吉隆、聂拉木、错那)、云南西部至西北部(保山、洱源、鹤庆、丽江、中甸)、贵州西部和四川西南部(布拖、木里)。生于林缘、草坡或山谷岩石上,海拔1300-2750米。也分布于尼泊尔、锡金和印度。
  本种有两种类型。一类叶较宽,基部渐狭成较明显的柄;蒴果近三棱状球形,长宽相等或较宽。另一类叶较狭,基部无明显的柄;蒴果三棱状倒卵形,长于宽。但这种相关特征有交叉和过渡,而且同一果序上的蒴果形状也有变化,所以我们暂予归并成一种。
