Flowers solitary, arising from the apical part of shoot, pedunculate. Peduncle arising horizontally, straight or slightly flexuose, light green, terete, 2–3 cm long, 1.5–2.0 mm in diameter, with 2–4(5) sterile bracts; bracts broadly ovate, concave, thin, scarious, white to light greenish, later dull yellowish – brown, papyraceous, obtuse to acute, 0.8–1.0(1.5) cm long, and 2–3(5) mm wide; uppermost bract narrowly ovate to oblong, concave, thin, scarious, almost white  to light greenish, obtuse, 0.8–1.0 cm long, 2–4 mm wide, with 3 veins, distant from fl ower.
