    Inflorescences
    Inflorescences up to 19 cm long with a peduncle up to 15 cm long, although commonly much less, leaf-opposed, sometimes terminal on lateral shoots, comprised mostly of male flowers usually with 2 female flowers below; male bracts 1.5–2 mm long, lanceolate to ovate-lanceolate, eglandular; male bracteoles 1 mm long, lanceolate to linear; female bracts 4–5 × 2 mm, ovate to ovate-lanceolate; female bracteoles 2 mm long, elliptic.
