Species Information

General:
Perennial herb from a short, stout rhizome or woody stem-base; stems erect, usually solitary, sparsely hairy, the hairs bristly or starlike, exuding milky juice when broken, 0.2-1.0 m tall.
Leaves:
Basal leaves well-developed, persistent, narrowly to broadly elliptic, nearly entire to shallowly to coarsely toothed, bristly-hairy on both surfaces, long soft-hairy on the stalks, 2-13 cm long, 1.5-5.5 cm wide; stem leaves lacking or 1-many and usually reduced upwards, not densely bristly-hairy beneath, egg-shaped to elliptic, often wider than 3 cm, at least some of them toothed near the base.
Flowers:
Heads with strap-shaped flowers, few to numerous in a flat- or round-topped inflorescence; involucres 8-12 mm tall; involucral bracts linear to linear-lanceolate, coarsely hairy with blackish, gland-tipped and often starlike hairs; ray flowers yellow.
Fruits:
Achenes ribbed, narrowed at the base, 2.5-3.5 mm long; pappus tawny or white.
Notes:
The taxonomy of the "H. murorum" group, as with many European Hieracia, is extremely difficult due to its polyploid-apomictic nature.
