|discussion=<p>In North America, <i>Ranunculus testiculatus</i> seems to be expanding its range rapidly in arid and semiarid areas. A second species of this subgenus, R. falcatus Linnaeus [Ceratocephala falcata (Linnaeus) Persoon], has been reported from North America, but all reports seem to be based on misidentified material of <i>R. testiculatus</i>.</p>
