Key characteristics

This species is a very distinct and can be differentiated from O. triangularis by its larger, lanceolate and rather papery leaves with strongly lobed margins, as opposed to the small, triangular, slightly fleshy leaves with revolute margins in O. triangularis. The secondary inflorescences are thyrsoid, emerge terminally and produce florets with white corollas and a pappus of white bristle-like hairs (setae) up to c. 3 mm long (Merklinger & Leubert, 2020).

Notes

Seed of this species is banked by the national seed bank of Chile, INIA.
