Plants annual, 3-15(-20) dm; roots also rarely arising from proximal nodes; rhizomes and stolons absent. Stems erect, branched distally, ribbed distally, hirsute proximally, stipitate-glandular distally, usually smooth proximally. Leaves: ocrea brownish to reddish brown, cylindric, 8-20 mm, chartaceous, base inflated or not, margins truncate, ciliate with bristles 2-7 mm, surface strigose to hirsute, not glandular-punctate, rarely stipitate-glandular; petiole (0.1-)0.5-1.5 cm, hirsute, leaves sometimes sessile; blade without dark triangular or lunate blotch adaxially, narrowly lanceolate, 6-18 × 1-3.5 cm, base tapering, margins antrorsely strigose, apex acuminate to attenuate, faces sparingly hirsute abaxially and adaxially, veins often hirsute, sometimes stipitate-glandular. Inflorescences terminal and axillary, nodding or drooping, usually interrupted, 10-100 × 5-10 mm; peduncle 20-50 mm, stipitate-glandular; ocreolae overlapping or not overlapping proximally, margins eciliate or ciliate with bristles to 1.3 mm. Pedicels ascending to spreading, 1-4 mm. Flowers (1-)2-8 per ocreate fascicle, homostylous; perianth roseate or purple, glabrous, not glandular-punctate, scarcely accrescent; tepals 5, connate in proximal 1/3, obovate, 2.4-3.2 mm, veins prominent or not, not anchor-shaped, margins entire, apex obtuse to rounded; stamens 5 (or 8), included; anthers pink, elliptic; styles 2, connate to middle. Achenes included, dark brown to black, biconvex, 1.8-2.5 × 1.5-2 mm, shiny, smooth. Flowering Jul-Oct.
