Leaves spreading and crowded at the tips of branches, sheathing at base; sheath glaucous to light green, 4–9 × 4–8 mm, coriaceous, striate, shoulder rounded to truncate, margin ciliate; lamina coriaceous, glaucous to light green, linear-triangular, 21–50 × (1.0–)1.3–2.5 mm, slightly concave, surfaces minutely verrucose and covered in short, white scabrid caducous hairs; margin serrulate, with 10–13 teeth per cm; apex triquetrous. Inflorescence an oblong raceme terminating lateral branchlets, dense, (13–)19–23(–28) mm long with (3–)6–9 flowers; inflorescence bracts persistent, longer than flower, coriaceous, subulate, 13.9–22.2 × 0.7–0.9 mm at base, rugose with serrulate margin; flower bract persistent, shorter than flower, coriaceous, keeled, broadly ovate, (4.5–)6.5– 8.0 × (2.5–)3–4 mm, adaxial surface scabrid in distal third, abaxial surface with scabrid hairs; margin white, ciliate; apex acute. Pedicel 1.5–2.0 mm long. Sepals green, ovate-lanceolate, (4–)5–6 × (1.5–) 2.0– 3.0 mm, shorter than corolla tube, adaxial surface glabrous with scabrid hairs at apex; abaxial surface with scattered scabrid hairs; margin white, ciliate; apex acute. Corolla white; tube cylindrical with mouth narrowed, 5.5–6.5 × 2.0–2.5 mm, glabrous; lobes reflexed, triangular, shorter than corolla tube, 1.8–2.0 × 1.5–2.0 mm, apex inflexed, subacute, adaxial surface papillate, abaxial surface glabrous. Stamens epipetalous, in upper third of corolla tube, filaments 0.5 mm long; anthers light yellow, oblong, 1 mm long, included.
