Pleurospermum cristatum de Boiss. in Bull. Soc. Bot. France 53: 434. 1906; Dunn in Journ. Linn. Soc. Bot. 39: 477. 1911.
二年生草本，高70-120厘米，全株无毛。根圆锥状，灰褐色，多少分枝。茎直立，中空，不分枝或上部分枝。基生叶或茎下部叶有长柄，叶片轮廓三角状卵形，通常三出2回羽状分裂，长15-28厘米，宽10-14厘米，末回裂片菱状卵形，长1.5-6厘米，顶端渐尖，基部下延，边缘有不整齐缺刻，叶柄基部扩展呈鞘状；茎上部的叶简化，有短柄或近于无柄。复伞形花序顶生的较大，直径达5厘米，侧生的较小；总苞片3-7，匙形，长1-2.5厘米，顶端尖，全缘，有狭的白色边缘；小伞形花序有花15-25；花白色；花柄长3-5毫米；花瓣卵圆形，长约1毫米，顶端内凹而有明显内折的小舌片；花柱基圆锥状。果实卵状长圆形，淡褐色，长4-5毫米，表面密生水泡状微突起，果棱突起，呈明显鸡冠状，每棱槽中有油管1，合生面2。
产宁夏，山西，陕西，甘肃，青海，河南，湖北，四川等省区。生于海拔1300-2600米的山坡林缘或山沟草地上。模式标本采自湖北宜昌。
本种外形同翼叶棱子芹 P. decurrens 很相似，但其果棱明显呈鸡冠状，很容易同有波褶皱翅的翼叶棱子芹相区别。
