Heads 1-30(-70). Peduncles 1.5-7 cm, short-pilose, sometimes stipitate-glandular distally; bracts foliaceous, grading to linear scales. Phyllaries in 3-4 series, linear, unequal, margins scarious, faces sparsely to densely short- to long-pilose, sparsely glandular. Ray florets (11-)16(-24); laminae 7-12 × 1-2 mm.

Bradburia pilosa grows in the western coastal plain province, southwestern central lowlands province, lower elevations of the Ozark Plateau province, and has possibly been introduced at a few locations in the interior low plateau province. It has possibly been introduced at a few sites in Kentucky, North Carolina, Virginia, and in Leon County, Florida.
