description
The long-stemmed man's shield grows as an annual herbaceous plant , has no sterile shoots and reaches a height of 2 to 5 cm. All parts of the plant are covered with star hair, the leaves and calyx parts are often bald or bare. The leaves arranged in a basal rosette are lanceolate and pointed, serrated or with entire margins.
The inflorescence shafts arise in several from the axils of the upper leaves. The umbellate inflorescence is spread out and multi-flowered. The flower stalks are very thin and considerably longer than the bracts at flowering time. The calyx is bell-shaped, 4 to 5 mm long and divided almost to the middle. The crown is white, has a yellow throat, is about 3 mm long and shorter than the calyx. It blooms in April and May, in fallow fields also in August.
The capsule is spherical, 3 mm long and shorter than the calyx. The seeds are abundant, roundish-angular in shape and about 0.5 × 0.75 mm in size.
The number of chromosomes is 2n = 40.
