Hymenoxys lemmonii ( Anglèis )

fornì da wikipedia EN

Hymenoxys lemmonii is a species of flowering plant in the daisy family known by the common names Lemmon's rubberweed, Lemmon's bitterweed, and alkali hymenoxys.[2] It is native to the western United States in and around the Great Basin in Utah, Nevada, northern California, and southeastern Oregon.[3]

Hymenoxys lemmonii is a biennial or perennial herb with one or more branching stems growing erect to a maximum height near 50 centimeters (20 inches). It produces straight, dark green leaves up to 9 centimeters (3.6 inches) long and divided into a number of narrow, pointed lobes. The foliage and stem may be hairless to quite woolly. The daisy-like flower head is generally at least 1.5 centimeters (0.6 inches) wide, with a center of 50–125 thick golden disc florets and a shaggy fringe of 9–12 golden ray florets.[4]

The species is named for John Gill Lemmon, husband of prominent American botanist Sarah Plummer Lemmon.[5]
