|discussion=<p>North American plants referred to <i>Rhynchospora</i> axillaris (Lamarck) Britton [Phaeocephala axillare (Lamarck) House by N. L. Britton and A. Brown (1913) and J. K. Small (1933)] are actually <i>R. cephalantha</i>. A photograph of the type specimen of <i>Schoenus</i> axillaris Lamarck (from P) reveals what appears to be an immature top of S. glomeratus [<i>R. glomerata</i> (Linnaeus) Vahl].</p>
