About
Enceliopsis argophylla, commonly known as the silverleaf sunray, is a North American species of flowering plant in the family Asteraceae. Other common names include nakedstem sunray and naked-stemmed daisy. It is native to the southwestern United States: Arizona (Mohave County), Nevada (Clark County), and Utah (Washington County), and can be seen a short distance east of Las Vegas, Nevada.
Where it grows
Found in Clark and Mohave Counties in the vicinity of the artificial reservoir Lake Mead, it grows on stony barren slopes at 1,000 to 1,500 m (3,300 to 4,900 ft) altitude. It often grows alongside the rare golden bear-claw poppy or Las Vegas bear-poppy Arctomecon californica. Both plants grow in a fragile gypsum crust on the soil, which when damaged facilitates the spread of invasive plants. Its habitat is threatened by the reservoir as well as off-road recreational vehicle use.
