Chamaephytes, native with distribution in the Southern Cone Region of South America.

Characteristics. Subshrub with many creeping branches, to 60 cm long, and densely pubescent ascending stems. Leaves with stipulates; ovate to triangular, margins crenate, glaucous, covered with short hairs. Flowers solitary; epicalyx with oval bracts; corolla with pink-lilaceous petals; nerves and basal stained red to violet. Fruit: a schizocarp, with reticulated mericarps.

Comments. This is a frequent species in the study area. It grows in shallow to moderately deep soils on slopes, including grassy slopes, and on summits. In the mountain ranges also grows Pavonia glechomoides A.St. Hil. , which differs from P. cymbalaria by the presence of long hair pubescence, suborbiculate leaves, thin epicalyx bracts, and white or pinkish petals with the basal stain purple.
