Pallenis spinosa reaches on average 60 centimetres (24 in) of height. Leaves are alternate, lanceolate or elliptical. The basal ones have short petioles, while the cauline ones are sessile or semiamplexicaul. A solitary inflorescence grows at the top of the branches. The large, slightly convex receptacle shows numerous, yellowish orange, hermaphrodite disc florets and two whorls of yellow ray florets. The long, villous, involucral bracts end in an apical sharp-pointed spine. The flowering period extends from May through July. Fruits are achenes of about 2–2,5 millimeters of length.
