葉狹線形，直，短或長於花葶，寬（1.5-）2-4毫米，平或凸平，肉質，邊緣微小粗糙，先端銳尖至逐漸漸狹，截形。花葶（20-）30-40厘米，圓柱狀，不成角，無翅，只在基部被葉鞘覆蓋。
佛焰苞片2瓣裂，通常早落，先端漸尖。傘形花序，疏鬆半球形，多花。花梗（2-）3-4倍於花被，通常無苞片。花被，白色或粉紅色或玫瑰粉或粉紅色，有光澤；
裂片有紅色，中脈細或沒有中脈，狹橢圓形或長圓狀橢圓形，4.5-5.5（-6）×1.5-2毫米，先端截形至銳尖；外部舟形。花絲鑽形，近等長，稍長於花被片，基部合生並與花被片貼生；
內部的比外部寬。子房卵球形，沒有凹的一種分泌糖液的外分泌結構。風格突出。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.
