Helenium apterum is a North American perennial plant in the sunflower family. It has been found only in the state of Durango in northwestern Mexico.[3][4] Turner, B. L. 2013. The comps of Mexico.

Helenium apterum is an perennial herb up to 100 cm (40 inches) tall with thick rootstocks producing only one stem with a single flower head. Leaves at the base can be up to 30 cm (1 foot) long, the leaves higher on the stem much smaller. The head is about 4 cm (1.6 inches) across, with a hemispherical yellow disc surrounded by about 14 yellow ray flowers.[3]
