Perennials 40–100 cm tall, hairy to sparsely hairy; rhizome ascending to ±erect, rarely
±creeping. Basal leaves usually up to 25 cm long, (5–) 8–13 (–20) mm wide; cauline leaves
usually 3–6, with upper ones to 17–20 cm long and 13 mm wide; all leaves acute, with
densely papillose-serrulate margin. Primary bracts long, leaf-like, herbaceous, often ±equalling
their partial inflorescences (lower inflorescence branches often in axils of upper cauline
leaves). Inflorescence a loosely branched drooping interrupted panicle constituting 1/3– 1/2 of
plant height, composed of long pedunculate interrupted partial panicles of numerous small,
cylindrical clusters usually 5–8 (–15) × 3–4 (–5) mm. Bracteoles membranous, ovate,
acuminate, c. 1 mm long, fimbriate-ciliate above. Tepals straw-brown to pale castaneous brown,
