岩韭形态特征
鳞茎单生或成对，圆筒状到圆锥形圆筒状，直径0.5-1.5厘米，附生于地下，根状茎通常不厚；鳞茎白色或灰色，膜质，先端裂。
叶狭线形，直，短或长于花葶，宽（1.5-）2-4毫米，平或凸平，肉质，边缘微小粗糙，先端锐尖至逐渐渐狭，截形。花葶（20-）30-40厘米，圆柱状，不成角，无翅，只在基部被叶鞘覆盖。
佛焰苞片2瓣裂，通常早落，先端渐尖。伞形花序，疏松半球形，多花。花梗（2-）3-4倍于花被，通常无苞片。花被，白色或粉红色或玫瑰粉或粉红色，有光泽；
裂片有红色，中脉细或没有中脉，狭椭圆形或长圆状椭圆形，4.5-5.5（-6）×1.5-2毫米，先端截形至锐尖；外部舟形。花丝钻形，近等长，稍长于花被片，基部合生并与花被片贴生；
内部的比外部宽。子房卵球形，没有凹的一种分泌糖液的外分泌结构。风格突出。花期7-8月。
Bulb solitary or paired, cylindric to conical-cylindric, 0.5--1.5 cm in diam., attached to a subterranean, normally not thick rhizome; tunic whitish gray, membranous, apex splitting. Leaves narrowly linear, straight, shorter or longer than scape, (1.5--)2--4 mm wide, flat to convex-flat, fleshy, margin minutely scabrous, apex acute to gradually attenuate, truncate.
Scape (20--)30--40 cm, terete, not angled, wingless, covered with leaf sheaths only at base. Spathe 2-valved, usually caducous, apex acuminate. Umbel laxly hemispheric, many flowered. Pedicels (2--)3--4 × as long as perianth, usually ebracteolate.

Allium spurium A. spirale, and A. senescens are closely related taxa, and have been united under the name A. senescens in treatments in other floras, e.g., FRPS and Fl. URSS.
