Pteronia glauca or boegoekaroo doesn’t sprout after fires. The grey leaves are elliptic and hairy, folding in slightly along the midribs.

The yellow flowerhead is narrowly cylindrical, about 5 mm in diameter. Flowerheads are clasped by rows of narrow, yellowish bracts that are not sticky. There are no ray florets. The tiny, yellow disc florets are star-shaped with five narrow, pointed lobes (Vlok and Schutte-Vlok, 2010).
