herbaceous, c. 6 cm × 1 mm, erecto-patent, exceeding inflorescence, with obtuse tip; upper
bracts gradually membranous; middle and upper cluster bracts membranous with long acute
tip. Inflorescence erect, usually congested and forming an elongated dense head 2–3 (–5) ×
0.7–1.0 cm, very often ±interrupted in lower part and lobulate, composed of 6 to many dense
clusters of 8–20 flowers, lower cluster sometimes remote or on a long peduncle at the axil of
the upper cauline leaf; peduncle smooth. Bracteoles 2.5–3.0 mm long, white-membranous,
long fimbriate-ciliate (whole inflorescence has a hairy appearance). Tepals subequal,
lanceolate, (2.4–) 2.8–3.2 mm long, entire or with a few teeth near the apex, acute; outer
tepal long acuminate, castaneous brown, whitish bordered or unbordered. Stamens 6; anthers
c. 0.6–0.9 mm long, slightly shorter or longer than 0.6–0.7 mm long filaments. Style 0.4–0.6 mm
long; stigmas 1.5–2.5 mm long. Capsule ±obovoid, obtuse or very slightly subacuminate,
castaneous brown, shorter than tepals; capsule segments 1.9–2.1 × 1.2–1.4 mm. Seeds
±ellipsoidal, castaneous brown, 0.9–1.1 mm long, 0.6–0.7 mm wide, with a broad whitish
