The earliest binomial for this species, Cladium distichum, is sometimes rejected, as it was based on a so-called ‘monstrosity’ with badly deformed spikelets (besides the normal lower glumes each spikelet bears a great number of exactly distichous empty upper glumes). The same ‘mon- strosity’ sometimes occurs in Rhynchospora rubra (see p. 717, notes).
