Barnadesia is a genus of flowering plants in the aster family, Asteraceae.[2][3] It is native to South America, where it is distributed from Colombia to northern Argentina, with most species occurring in the Andes.[4] Common names include clavelillo, chivo caspi, espino de gato, and espino santo.[4]
These plants are mainly shrubs and small trees,[5] the largest exceeding four meters in height.[6] The stems are spiny. The flower heads contain pink, red, or purple florets, including 8 to 13 hairy ray florets and usually either one or three disc florets. The ray floret yields a fruit with a plumelike pappus, and the fruit from a disc floret has a more “bristle-like contorted pappus”.[5]
