    Inflorescences
    Inflorescence of (2–)4–9 flowers; peduncles 6–36 cm. long, mostly leaf-opposed, pubescent with short and long hairs; free part of the pedicel 2–6 mm. long; bracts usually more than the number of the flowers, linear-lanceolate, 5–10 mm. long, 1–1.5 mm. wide, covered with few but long hairs.
