Perdicium piloselloides Vahl (1791) View in CoL : 38.

Cryptophytes; native with wide distribution in the Southern Cone Region of South America.

Characteristics. Perennial herb with fascicled thick roots. Leaves in a basal rosette, green in the adaxial surface and white in the abaxial one, 0.7–1.5 cm wide, with oblanceolate shape, retrorsely-dentate margin, acute apex and long attenuate base ending in a sheathed petiole. Inflorescence: solitary discoid capitulums at the end of a lanate peduncle, with glabrous phyllaries and three kinds of white florets; ray outer florets (female flowers), filiform intermediate florets (female flowers) and bilabiate disc

florets in the center of the head (hermaphrodite flowers). Achenes with a beak and crowned by a reddish pappus.

Comments. This is an infrequent species in the study area. It grows in shallow to moderately deep, damp soils of the summit and grassland slopes. Chaptalia exscapa (Pers.) Baker is a species frequently found in the Tandilia mountain range, but it differs from C. piloselloides by the 2 to 4 cm wide leaves, achenes without beak, and lack of scape when flowering.
