50-100 cm, colonial; rhizomatous, woody.
1-5+, erect, straight (± stout, light to dark brown), proximally sparsely to moderately short-strigose, distally densely so, stipitate-glandular.
(dark green) thick, firm, margins revolute (sometimes ± undulate), scabrous; basal early deciduous, sessile or subpetiolate, blades spatulate to obovate [size unknown], bases cuneate, margins entire to ± serrate, apices acute, faces finely scabrous; proximal cauline withering by flowering, sessile, blades (adaxially obscurely veined) oblong to lanceolate or narrowly obovate to oblanceolate, proximalmost ± pandurate, 20-70 × 10-20 mm, gradually reduced distally, bases auriculate-clasping, margins entire, finely scabrous, faces finely scabrous, stipitate-glandular; distal sessile, blades lanceolate to oblanceolate, 14-50 × 6-11 mm, reduced distally (much smaller on branches and grading ± abruptly into bracts), bases ± auriculate-clasping to subclasping, margins entire, apices mucronate to white-spinulose, faces scabrous, sometimes sparsely to moderately stipitate-glandular.
in narrow, racemiform to ± broad, paniculiform arrays, sometimes borne singly on branches, branches initially patent then ascending, leafy.
densely short-strigose, ± densely short-stipitate-glandular, bracts 1-8+, spreading to reflexed, linear to narrowly oblong-lanceolate, strigillose, stipitate-glandular, grading into phyllaries.
campanulate to hemispheric, 8-10 mm.
in 4-7 series, spatulate-oblong to lanceolate, unequal, innermost linear-lanceolate, bases tan, ± indurate in proximal
