Scales 45-85 µm in diam., 8-celled with a number of tangential walls. Inflorescence a spike, up to 25 mm long, singly or in pairs at the apices of previous year's growth and in axils on current extensions; peduncle and rhachis light green, sparsely puberulous, densely lepidote. Flowers sessile, 4-merous; bracteoles ± 0.5 mm long, lepidote; lower receptacle 2-2.3 mm long including restriction at junction with upper receptacle, brownish green, sparsely puberulous with dense yellowish stalked scales; upper receptacle cupuliform, surrounding the disc, distal portion infundibuliform, overall length ± 3 mm, width at sepal apices ± 3 mm, green, sparsely puberulous with whitish scales.
