AVH map***

This species is highly polymorphic and has been much confused with O. stellulata. A suite of specimens from the ST, which may be worthy of recognition at specific rank, have linear leaves (15–60 mm long, 2–4 mm wide) with strongly revolute margins, heads with 14–17 ray florets. They grow on steep rocky hillsides and river gorges.
