|discussion=<p><i>Oplismenus hirtellus</i> grows at scattered locations in the southeastern United States, extending south in subtropical and tropical habitats to Argentina. Scholz (1981) recognized 11 subspecies and two forms within the species, but they overlap, both morphologically and geographically. The key below is included for convenience. It includes the three subspecies attributed to the Flora region. In addition, a variegated form culti</p>
