Crepis occidentalis
species of plant

Crepis occidentalis is a North American species of flowering plant in the family Asteraceae known by the common names western hawksbeard, or largeflower hawksbeard. It is native to western Canada (British Columbia, Alberta, Saskatchewan) and the western United States (from the Pacific to the western Great Plains).
Crepis occidentalis grows in many types of habitat. It is a perennial herb growing a grayish woolly branching stem to about 40 centimeters (16 inches) in height from a deep taproot. The woolly, toothed leaves are up to 30 centimeters (12 inches) long at the base of the plant. The inflorescence produces several clusters of flower heads with hairy, often glandular phyllaries and many yellow ray florets but no disc florets. The fruit is a ribbed achene with a frilly pappus at the tip.

Why this record matters
“Crepis occidentalis” is worth following because a concise public description often conceals a longer documentary argument. Here, Crepis, occidentalis and species provides the most credible route into that argument.
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 Jun 28, 2025. The linked authority identifier is Q5184283. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
