Vegetative characteristics
The horse stool is a perennial herbaceous plant that usually reaches heights of 15 to 50 centimeters. The bare stalk has a tuft of dead leaves at the base. The approximately 10 to 20 centimeters long blue-green leaves are three to four times pinnate to pinnate. The tips of the leaves are narrow, linear and around one millimeter wide. The stalks of the basal leaves are deepened in a groove-like manner.
Generative characteristics
The flowering time of the horse stool extends from July to October in Central Europe . The double umbels usually have no bracts and five to twelve umbel rays, which are downy hairy at least on the inside. The husk leaves of the small cones are grown together like a cup almost to the tip. The flower stalks are 1 to 2 millimeters long. Sepals are mostly indistinct. The petals are white and glabrous. The front edge of the petals is outlined to notched. The petal wing is a maximum of a quarter as long as the petal. The hammered lobule ( lobulum inflexum ) is belt-shaped and one fifth as long to as long as the petal without wings. The fruit is ribbed.
The chromosome number of the species is 2n = 20.
