Grindelia ciliata
species of plant
Grindelia ciliata (syn. Grindelia papposa, Haplopappus ciliatus, and Prionopsis ciliata) is a species of flowering plant in the family Asteraceae known by the common names Spanish gold, goldenweed, and waxed goldenweed.
Grindelia ciliata is native to sections of the central United States, primarily the Great Plains from Iowa and Nebraska south to Texas and New Mexico. There are also isolated populations in Arizona and apparently naturalized populations in California, Maryland, Michigan, and the Mississippi Valley.
Grindelia ciliata grows in prairies and grasslands, and in disturbed areas such as roadsides and along railroad tracks.
Grindelia ciliata is an annual or biennial shrub sometimes as much as 150 cm (5 feet) tall, its upper stem branching. It is hairless. The leaves are alternately arranged, up to 8 cm (3.2 inches) long, their spiny-toothed blades longer than wide. The top of the stem is occupied by an inflorescence of several flower heads, their hemispheric bases up to 2.5 centimeters (one inch) wide and lined with many small, green phyllaries with curving tips. Each flower head may have up to 30 narrow, pointed yellow ray florets between 1 and 2 centimeters (0.4-0.8 inches) long, surrounding a center of yellow disc florets.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Grindelia ciliata”, 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 Jun 28, 2025. The linked authority identifier is Q5609418. 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 source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
