Chamaephytes,native with distribution in the Southern Cone Region of South America. Least Concern ( Delucchi 2006).

Characteristics. Suffrutescent with many branches and leaves, 20–60 cm tall. Leaves pubescent, linear, to 2.5 cm long and 2 mm in diameter and with obtuse apex. Capitulums: isomorph, with a brief peduncle and pinkish tubular florets, disposed in dense corymbs. Achenes: cylindrical, with glabrous surface and reddish pappus.

Comments. This is an infrequent species in the study area. It grows in full sunlight conditions, in shallow soils and deep cracks of rocks on the grassland slopes and on the summit. This species is similar to S. multiaristata Spreng and S. aristata Don but S. multiaristata presents long peduncles and S. aristata has rhombic leaves.
