Species of thistle
Cirsium turneri is a North American species of plants in the tribe Cardueae within the family Asteraceae. Common names include cliff thistle.[1] The species grows in crevices in limestone cliffs in northern Mexico (Chihuahua, Coahuila)[1] and western Texas (Brewster, Terrell, Val Verde Counties).[2][3]
Cirsium turneri is a perennial herb up to 45 cm (18 inches) tall. Leaves have small, narrow spines along the edges. Flower heads are sometimes produced one at a time, sometimes in small groups, each head with red or reddish-purple disc florets but no ray florets.[1]
