Agoseris aurantiaca
species of plant
Agoseris aurantiaca is a species of plant in the family Asteraceae, commonly called orange agoseris, pink false dandelion or mountain dandelion. It is widespread in western North America.
Description
Agoseris aurantiaca is a perennial herb or subshrub growing to 60 centimeters (24 inches) in height. It produces a basal rosette of leaves, which are 5–35 cm (2–14 in) long and entire or with irregular tooth-like lobes. There is no stem, but it does produce several stem-like peduncles. Between June and August, each peduncle bears a single flower head 2.5 cm (1 in) in width, 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.
The binominal name "Aurantiaca" means "orange-red". The flower head matures into a ball-like head of beaked achenes, each with a terminal pappus of numerous, white bristles.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Agoseris aurantiaca”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Dec 30, 2025. The linked authority identifier is Q4693599. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
