Peduncles up to 8, terete, glabrous or ciliolate on angles, suberect or slightly spreading in fruit; outer bracts green or submembranous toward base with narrow colourless membranous margins, 12-20 mm long, lightly striate (5 to 7 veins/mm), inner bracts with wide brown-edged membranous margins. Flowers white or pale yellow to pale apricot-coloured, often with darker veins, cup yellow with brown marks, outer tepals greenish or darkly feathered on reverse; perianth tube funnel-shaped, 3-5 mm long; tepals oblanceolate, 15-30 x 6-8 mm.
