Grindelia integrifolia
de Candolle in A. P. de Candolle and A. L. P. P. de Candolle, Prodr. 5: 315. 1836.
Perennials,
20—80(—100+) cm.
Stems
erect, stramineous to red-brown, 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.

Flowering Jun—Sep. Meadows, ditches, marshlands; 0—200 m; B.C.; Oreg., Wash.
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.
