distal sessile, blades oblanceolate, 30–80 × 6–15 mm, gradually reduced distally, bases auriculate-clasping, apices acute to obtuse, mucronate to minutely white-spinulose, faces moderately to densely short-soft-hairy, sparsely to moderately stipitate-glandular.

firm, margins serrate to serrulate, scabridulous, apices acute to shortly acuminate, apiculate to mucronate, abaxial faces glabrous, adaxial scabridulous;

basal withering by flowering, long-petiolate (petioles narrowly winged, sheathing), blades elliptic, 50–250 × 10–50 mm, bases attenuate;

proximal cauline withering by flowering, long-petiolate to subpetiolate (petioles winged, bases expanded, sheathing), blades elliptic to lanceolate or oblanceolate, gradually reduced distally, 70–110 × 15–35 mm, bases attenuate;

distal subpetiolate or sessile, (petioles broadly winged, bases sheathing to clasping), blades elliptic, 10–70 × 1–30 mm, progressively reduced distally, more strongly so on branches, bases attenuate to cuneate, clasping, margins serrulate or entire.

dilated distally, 0.3–4 cm, densely short-hairy, stipitate-glandular, bracts 1–4, foliaceous, linear to narrowly lanceolate, densely short-hairy, stipitate-glandular, grading into phyllaries.

in 5–6 series, linear-lanceolate or -oblanceolate to linear, slightly unequal, bases indurate 1/3–1/2, margins narrowly scarious, hyaline, sparsely and remotely ciliolate, green zones lanceolate to linear, outer distally foliaceous, sometimes constricted in middle, apices spreading to squarrose, long-acuminate, apiculate, faces glabrous.

in leafy, often crowded, paniculo-corymbiform arrays.
