根粗壮，近块根状；鳞茎单生，圆柱状至近圆柱状；鳞茎外皮淡棕色，破裂成平行的纤维状。叶3-5枚，条形，扁平，常比花葶长，长7-23厘米，宽2-5毫米。花葶高5-15厘米，有时可高达37厘米，粗约1毫米，下部约1/4-2/5被叶鞘；总苞膜质，单侧开裂或2裂，具短喙，近与花序等长，宿存或早落；伞形花序球状，具多而密集的花；小花梗近等长，有时外层的稍短，等长于花被片或为其1.5-2倍长，基部无小苞片；花白色；花被片等长，披针形，长4.5-6毫米，宽1.4-2.2毫米，基部常呈圆形扩大，先端渐尖或不规则的2裂；花丝等长，约比花被片短1毫米，锥形，在基部合生并与花被片贴生；子房为具3圆棱的扁球状，基部收狭成短柄，不具凹陷的蜜穴，外壁具细的疣状突起，每室2胚珠；花柱与子房近等长或略长；柱头小，不显著。花果期7-9月。
产西藏（东南部）和青海南部（治多、玉树）。生于海拔2200-5400米的山坡、草地或河滩沙地。尼泊尔、锡金和不丹也有分布。
本种在外形上易与宽叶韭 A. hookeri Thwaites 混淆。但宽叶韭的根不呈近块根状，子房外壁无疣状突起，每室1胚珠，而易与本种区别。
