| Description: |
Perennial up to 60 cm tall, loosely caespitose, sparsely hairy; rhizome short, ascending, without stolons. Basal leaves up to 20–24 cm long, usually 4.5–11 mm wide. Cauline leaves (2–) 3, with upper one usually 6–9 cm long, 3.5–6.5 mm wide. All leaves with obtuse swollen tip and densely papillose-serrulate margin. Lower bract herbaceous, of variable length, usually 2–4 cm long, substantially shorter than inflorescence. Inflorescence sometimes not only terminal but also in axil of upper cauline leaf, of one subsessile and numerous (usually 5–30) clusters; clusters small, hemispherical, usually 2–7-flowered. Peduncles thin, c. 0.3 mm in diam., often arcuate or flexuose, smooth to densely papillose above, with secondary branches; secondary branches often 3–5 per branch (inflorescence branched in a way similar to that of sect. Anthelaea), with longest branches up to 10 cm. Bracteoles ovate, scarious to pale straw-brownish, c. 1.5 mm long, ciliate. Tepals (1.8–) 2.2–2.4 mm long, ±equal, entire, pale brownish, acute to subobtuse with an acute mucro and broad membranous to straw-brown margins. Stamens 6; anthers 0.6–1.0 mm long; filaments 0.5–0.6 mm long; style 0.4–0.6 mm long; stigma 1.0–1.2 mm long. Capsule obovoid, submucronate, pale brownish, equalling or longer than perianth; capsule segments 2.0–2.2 × 1.3–1.4 mm. Seeds 0.8–0.9 mm long, 0.7–0.8 mm wide; appendage 0.1–0.2 mm long, fibrillate.
