Crepis pygmaea (commonly pygmy hawksbeard)[1] is a species of flowering plant in the genus Crepis in the family Asteraceae.
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 (3⁄4 to 1+1⁄4 in) and contains only ray florets. The bracts are bell-shaped, white, and 10 to 15 millimetres (3⁄8 to 5⁄8 in) long.[2] The fruits are 4 to 6 millimetres (3⁄16 to 1⁄4 in) long. The calyx is 7 to 10 millimetres (1⁄4 to 3⁄8 in) long and white.[2]
The chromosome number is 2n = 8 or 12.[3]
