Pectis imberbis is a species of flowering plant in the family Asteraceae. It is native to Chihuahua and Sonora in Mexico and Arizona in the United States.[2][3] It is known by the common names beardless chinchweed, beardless fetid-marigold, hierba de venado,[2] and tall chinchweed.[3]
This species is a perennial herb growing erect up to 1.2 meters tall from a woody caudex. The linear leaves are up to 5 centimeters long and only 1 or 2 millimeters wide. Flower heads are borne singly or in loose arrays. Each flower head has a cylindrical body lined with glandular phyllaries. It contains 5 yellow ray florets with a few disc florets at the center.[3] The florets may turn reddish or purple with age.[2] Flowering occurs after summer rainfall in August through October.[2]
This plant grows in many kinds of habitat, including woodland, grassland, and dry shrubland.[3] It can generally thrive in disturbed habitat,[2] but overgrazing may eliminate populations.[3]
