Gmelin based his own description on those for the "grass finch" that had been described by John Latham in 1783 and by Thomas Pennant in 1785. The vesper sparrow is now the only species placed in the genus Pooecetes that was introduced in 1858 by the American naturalist Spencer Baird. The genus name combines the Ancient Greek ποα (poa) meaning "grass" with οικητης (oikētēs) meaning "dweller". The specific epithet gramineus is Latin meaning "grassy" or "grass-like". Three subspecies are recognised. P. g. gramineus (Gmelin, JF, 1789) – breeds in southeast Canada to east USA P. g. confinis Baird, SF, 1858 –…
