General Information

Plants perennial, occasionally bi-ennial, glabrous or very indis-tinctly papillose normally only on veins of leaf blades abaxially, with fusiform, vertical rootstock. Stems erect, branched distal to middle, 40-100(-150) cm. Leaves: ocrea deciduous, rarely partially persistent at maturity; blade lanceolate to narrowly lanceolate or lanceolate-linear, normally 15-30(-35) × 2-6 cm, base cuneate, truncate, or weakly cordate, margins entire to subentire, strongly crisped and undulate, apex acute. Inflorescences terminal, occupying distal 2 of stem, dense or interrupted at base, narrowly to broadly paniculate, branches usually straight or arcuate. Pedicels articulated in proximal 3, filiform, (3-)4-8 mm, articulation distinctly swollen. Flowers 10-25 in whorls; inner tepals orbiculate-ovate or ovate-deltoid, 3.5-6 × 3-5 mm, base truncate or subcordate, margins entire or subentire to very weakly erose, flat, apex obtuse or subacute; tubercles normally 3, rarely 1 or 2, unequal, at least 1 distinctly larger, more than (1-)1.5 mm wide. Achenes usually reddish brown, 2-3 × 1.5-2 mm. 2n = 60.
