Perennials, 20–80 (–100+) cm. Stems erect, stramineous to redbrown, villous and/or stipitate-glandular (at least distally). Cauline leaf-blades lanceolate or lance-attenuate (broadest proximal to midpoints), 35–70 (–90) mm, lengths 2–4 (–10) times widths, bases usually clasping (± cordate), margins usually entire, rarely serrate to denticulate (teeth apiculate), apices acute to attenuate, faces stipitate-glandular. Heads in corymbiform arrays or borne singly. Involucres broadly urceolate to globose, 8–12 × 12–20+ mm (usually subtended by leaflike bracts). Phyllaries in 5–6 series, spreading to appressed, linear or to lance-linear or lanceolate, apices slightly recurved, straight, or incurved, filiform to subulate, ± stipitate-glandular, sometimes moderately resinous as well. Ray-florets 10–35; laminae 8–15 (–20) mm. Cypselae stramineous, 3–5 mm, apices coronate to knobby, faces smooth or striate; pappi of 2–3 contorted to curled, usually smooth, sometimes barbellulate, subulate scales 2.5–4 mm, shorter than disc corollas. 2n = 12.


Phenology: Flowering Jun–Sep.
Habitat: Meadows, ditches, marshlands
Elevation: 0–200 m

Discussion

But for the stipitate-glandular apices of the phyllaries, plants of Grindelia integrifolia are very much like some plants treated here in G. hirsutula. Taxonomic status for plants that have been called G. integrifolia should be reconsidered.
