Characteristics

Herbs 10-20 cm tall, perennial, rosulate, with a woody caudex or rootstock. Stems several from rosette leaf axils, to 40 cm, decumbent, leafy, each usually producing a secondary leaf rosette at a node in its middle third and with a single or few ± ascending-erect remotely leafy secondary flowering stems. Rosette leaves spatulate to rarely elliptic, 5-15 × 0.5-4.5 cm, usually somewhat fleshy, undivided or more rarely pinnatifid to pinnatisect with ovate to lanceolate lateral lobes, glabrous, base cuneately attenuate, margin entire or shallowly dentate, apex usually rounded. Lower and middle stem leaves similar to rosette leaves but smaller, base semiamplexicaul, apex obtuse to acute. Upper stem leaves obovate to ovate, base auriculately clasping, apex subacute to obtuse. Synflorescence corymbiform, with few to several capitula. Capitula with 8-12 florets; peduncle slender. Involucre narrowly cylindric, 7-9 mm. Phyllaries glabrous; outer phyllaries few, ovate, longest ca. 2 mm, apex ± acute; inner phyllaries 8, apex subacute. Achene brownish, subfusiform, 3-4 mm, scabrid, apically attenuate or with a less than 0.5 mm beak. Pappus white, 3-4 mm. 2n = 10*.
