Pallenis spinosa, commonly known as spiny starwort or spiny golden star, is an annualherbaceous plant belonging to the genus Pallenis of the family Asteraceae. The Latin name of the genus is derived from palea (chaff), referring to the chaffy receptacle, while the species name spinosa, meaning spiny, refers to the spiny bracts surrounding the flowers.
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.
