Ranunculus ficaria L. (RANUNCULACEAE)— Jefferson County: Edge of low woods at south end of soccer fields, Mountain Brook Elementary School, Mountain Brook; 33u28.8569N, 86u46.1929W; 13 March 2007, L. J. Davenport 3627 (SAMF, UNA, UWAL).
Significance. The presence of this taxon at the Mountain Brook soccer fields was reported to the author in early March 2007, by W. Mike Howell; it was collected shortly thereafter. Visits to the above collecting site over the succeeding three years reveal that the species is completely naturalized, growing prolifically in low woods bordering the school grounds. This is the first report, then, of the establishment of this invasive species in Alabama.
