Diagnostic description

O. nana is sometimes confused with pinnatifida but it is easily recognized on the achenes, which lack pappus, but have developed stylopodium. From: Bremer, K. 1972. The genus Osmitopsis (Compositae). Bot. Not. 125: 9-48. [All rights reserved]

Habitat

Grows in rock crevices. From: Bremer, K. 1972. The genus Osmitopsis (Compositae). Bot. Not. 125: 9-48. [All rights reserved]
