Pectis imberbis |
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]
