Information

Plants perennial, glabrous or very indistinctly papillose normally only on branches of inflorescence, or on veins of leaf blades abax-ially, with fusiform, vertical rootstock. Stems erect, branched distal to middle, 50–120(–160) cm. Leaves: ocrea deciduous or partially per-sistent at maturity; blade broadly lanceolate to ovate-lanceolate or oblong-lanceolate, normally 25–50(–60) × 7–15 cm, ca. 3–4 times as long as wide, base broadly cuneate, rounded-truncate, or slightly cordate, margins entire, undulate or weakly crisped, occasionally flat, apex acute or subacute. Inflorescences terminal, occupying distal 1/2 of stem, normally dense, narrowly paniculate, branches usually straight or arcuate. Pedicels articulated in proximal 1/3, filiform, 4–9 mm, articulation distinctly swollen. Flowers 10–20 in whorls; inner tepals broadly orbiculate or reniform, (4.5–)5–6(–7) × (4.5–)5–7(–7.5) mm, base usually distinctly cordate, margins entire or subentire to very weakly erose, flat, apex obtuse or, rarely, subacute; tubercles normally absent,sometimes with 1 indistinct tubercle or slightly thickened midvein less than 1–1.3 mm wide. achenes dark brown or brown, (2.5–)3–3.5(–4) × 1.5–2 mm. 2n = 60,.
