Notes: FNA23: "Scirpus pallidus has been confused with S. atrovirens. The awned rather than mucronate scales distinguish S. pallidus from all similar species. The perianth bristles are similar to those of S. atrovirens; the scales of S. pallidus are almost always black, rather than brownish as in S. atrovirens. Inflorescences of S. pallidus consist of relatively few, large glomerules (the largest glomerule in the inflorescence usually has 50 or more spikelets). Some individuals of S. atrovirens may have glomerules with as many as 65 spikelets.

Scirpus pallidus occasionally hybridizes with S. atrovirens."
