A perennial herb spreading by means of underground runners, flowering stems simple or rarely forking at the base, up to 60 cm tall, hispid, leafy. Basal leaves rosetted, usually withered at flowering, up to 15 x 4 cm, elliptic, apex obtuse, base tapered to a petiole-like region, margins nearly entire or callose-denticulate to crenate, both surfaces hispid with long coarse jointed pointed hairs or sometimes hairs nearly confined to the margins and veins, minutely glandular as well, lower cauline leaves similar, becoming smaller and oblong to lanceolate upwards and passing into lanceolate, acute to acuminate, inflorescence bracts, all cordate-clasping. Heads c. 4 mm across when pressed, many in compact corymbose clusters corymbosely arranged. Involucral bracts in 2 series, shorter than the pappus, linear-lanceolate, glandular, median veins resinous. Achenes c. 1 mm long, turbinate, slightly compressed, thinly hairy. Pappus bristles scabrid. Flowering between February and May, mainly in March and April.
