Description

Vegetative features

The pygmy hawksbeard grows as a perennial herbaceous plant and reaches a height of 5 to 15 centimetres (2.0 to 5.9 in). The stems are arching and ascending, mostly branched, one or more heads, white tomentose or glabrous, often tinged with purple. [2] The plant has few leaves. The above-ground parts of the plant are hairy. [2]

The lower leaves are heart-shaped and usually long-stemmed. The upper leaves are irregularly pinnate with a very large end section and small side sections. [2] The underside of the leaf is often tinged with purple.

Generative traits

The flowering period extends from July to August. The cup-shaped inflorescence has a diameter of about 2 to 3 centimetres (34 to 1+14 in) and contains only ray florets. The bracts are bell-shaped, white, and 10 to 15 millimetres (38 to 58 in) long. [2] The fruits are 4 to 6 millimetres (316 to 14 in) long. The calyx is 7 to 10 millimetres (14 to 38 in) long and white. [2]

The chromosome number is 2n = 8 or 12. [3]
