Chamaephytes; endemic to mountain ranges of Buenos Aires province. Least Concern ( Delucchi 2006).

Characteristics. Shrub with many branches, to 40 cm tall, with pinnatisect, spiniform and rigid leaves, 1–2.5 cm long. Capitulum radiate, bell-shaped, 7 mm long, with white ray outer florets and yellow tubular disc florets. Achenes with glandular and pubescent surface, 3.5–4 mm long, crowned by a white pappus.
