Arnica mollis is one of the hairiest members of this genus; leaf edges, leaf faces, stems and phyllaries all have a covering of long silky white hairs, often glandular (sticky). The thick stems bear 2 to 4 pairs of leaves (usually 3), and may be single or lightly branched towards the top. Leaves are sessile, lacking any stalks. Leaf edges are entire or irregularly toothed, while the tips are pointed.

Flower heads (single or up to 7) consist of between 10 and 22 pointed green phyllaries, the same number of yellow ray florets and several dozen disc florets. Rays have a few lengthwise grooves, and two notches at the tip. Phyllaries are relatively broad, lanceolate in shape, and bent back to a small extent, near their tips, which may be reddish along the edges. Plants inhabit mountainous areas, up to 13,000 feet.
