The bristle Pippau is an annual herbaceous plant and reaches heights of growth of 8 to 80 centimeters. The stem is erect. The leaves are egg-shaped to elongated, light green, at least bristly hairy on the underside, ciliate on the edge or glabrous. The lower leaves are up to 30 cm long and up to 8 cm wide, narrowed into the petiole and toothed to pinnate with a larger end lobe. The stem leaves are also pinnately split and sitting with a spike-shaped base.
There are cup-shaped partial inflorescences in a cerebellar total inflorescence. The flower heads sit on yellow or fox-red, bristly haired stems and have a diameter of 10 to 14 mm. The envelope is 8 to 10 mm long and 4 to 10 mm wide. The bracts are conspicuously covered with bright bristles. The flowers are light lemon yellow, the style is dark green. The achenes are 3 to 5 mm long, yellow-brown, have ten ribs and are narrowed into a beak. The pappus is white.
The flowering period extends from June to September.
The number of chromosomes is 2n = 6 or 8.
