Floral bracts tubular, 1.3-1.8 mm, tip obtuse. Pedicel and ovary 4-7.5 mm, with the node 0.8-2 mm from the floral bract. Flowers moderately opening. Median sepal ovate, 3.6-6 by 2-2.8 mm, index 1.6-3, tip acute to shortly acuminate; margins glabrous or slightly papillose towards the tip; thin; surface glabrous (see note).
