White Prairie Aster (Aster falcatus).
This is a secondary selenium accumulator. It is a branched perennial plant of the dry plains with extensive spreading roots and stalks. The leaves are 0.4 to 1.2 inches (1 to 3 cm) long, linear, and densely hairy, giving the plant a rough feeling. The flowers are small and daisy-like with white ray flowers about 1/ 8 inch (3 to 4 mm) long that produce many tawny pappus bristles in a head during late summer and fall.
