Some legitimate versions of the scientific name for the ‘Northern Bulrush’ or ‘Singlespike Sedge’. The genus (Carex), species (scirpoidea), and subspecies (convoluta) may be annotated (var., subsp., and ssp.) or include or omit the name of the original authority for the infraspecies (Kükenthal), or for the species (Michaux), or for the current infraspecific combination (Dunlop). The name of the authority is sometimes abbreviated, sometimes differently spelled, and may be with or without initials and dates. This list is not complete. Image courtesy of [42]
