Each inflorescence has three to five nodes with three to five spikes at each node. The mal spikes are located at the end of the culm and have a linear shape with a length of 17 to 45 mm (0.67 to 1.77 in) and a width of 1 to 1.5 mm (0.039 to 0.059 in). the female spikes are located laterally and have a narrow cylindrical shape that are 4 to 4.5 cm (1.6 to 1.8 in) in length and about 3 m (9.8 ft) wide.[2]
