鳞茎数枚聚生，圆柱状，粗0.3-0.5厘米；鳞茎外皮暗褐色，破裂成纤维状，下部近网状，稀条状破裂。叶狭条形，扁平，比花葶短，宽2-5毫米。花葶圆柱状，高15-40厘米，有时矮到5厘米，下部被叶鞘；总苞单侧开裂，早落；伞形花序半球状，具多而密集的花；小花梗近等长，比花被片短或与其等长，基部无小苞片；花钟状，天蓝色；花被片卵形或卵状矩圆形，先端钝，长6-10毫米，宽3-4.5毫米，内轮的边缘常具1至数枚疏离的不规则小齿，且常比外轮的稍长而宽；花丝等长，为花被片长度的1/2-2/3，基部合生并与花被片贴生，合生部分高约1毫米，内轮的基部扩大，有时每侧各具1齿，外轮的基部也常扩大，有时每侧亦各具1齿；子房近球状，腹缝线基部具明显的有窄帘的凹陷蜜穴；花柱比子房短或近等长。花果期7-9月。
产宁夏（南部）、陕西（西南部）、甘肃（南部）、青海（东部和南部）、四川（西北部至西南部）、西藏（东南部）和云南（西北部）。生于海拔2400-5000米的山坡、草地、林缘或灌丛下。印度、尼泊尔、不丹和锡金也有分布。
本种以条形、扁平的叶，天蓝色的花，花丝比花被片短，花被片卵形至卵状矩圆形，内轮边缘常具小齿而易被识别。本种与齿被韭 A. yuanum Wang et Tang 极为相似，又常混生在一起，其区别在于齿被韭的叶为背面成龙骨状隆起的条形，干后常扭卷，花被片先端渐尖，特别是叶的特征在野外极易掌握，能准确地把它与具扁平而条形叶的本种分别开。
