The leaves have pressed-down hairs, especially on the paler lower side, and dry to a green, membranous texture. The petiole is short at 5 to 10 millimeters long. The spikes are terminal, measuring 1 by 30 to 50 millimeters, with loosely spaced flowers. The peduncle is scarcely 5 millimeters long and covered with woolly, straight hairs. The floral bracts are round and shield-shaped (peltate), thin and large. The ovary is immersed, ovoid, and has a small shield-like structure called a scutulum.
