Agoseris aurantiaca is a liguliferous species in the Asteraceae or sunflower family, and is commonly called orange agoseris or mountain dandelion. It is widespread and common in western North America from Alaska and western Canada southward to California, Arizona, and New Mexico. It also occurs disjunctly in the Chic-Choc (Gaspe Peninsula) and Otish Mountains (Laurentian Plateau) of Quebec. This is primarily a species of mountainous regions and may be found in wet to dry habitats. It is a perennial herb producing a basal rosette of leaves. There is no stem, but it does produce several stem-like peduncles, each peduncle bearing a single flower head surrounded by glabrous to hairy phyllaries. The head is ligulate, containing several ray florets but no disc florets. The florets are most commonly orange but are occasionally yellow, pink, red, or purple. "Aurantiaca" means "orange-red".[1]:111 The flower head matures into a ball-like head of beaked achenes, each with a terminal pappus of numerous, white bristles.
