Шаблон:Short description Шаблон:Speciesbox
Hazardia cana is a rare North American species of shrubs in the family Asteraceae known by the common names Guadalupe hazardia, San Clemente Island hazardia, or simply island hazardia.[1] It is native to San Clemente Island, one of the Channel Islands of California, and to Guadalupe Island (part of the State of Baja California).[2][3][4]
Hazardia cana is a bushy shrub reaching Шаблон:Convert high. It has woolly, glandular herbage of oblong, sometimes finely toothed leaves Шаблон:Convert long. At the ends of its grayish stems it produces cylindrical flower heads. Each flower head has several rows of dark-colored phyllaries and an open end revealing disc florets and longer protruding ray florets. The florets are yellow when young but may age to red or purple.[5] The main threat to this species on San Clemente Island was the presence of feral goats. The goats have been removed from the island and the plant is recovering.
