typifications for galactia purshii and g. volubilis (fabaceae)

Abstract

The pervasive difficulties encountered with studying Galactia in the eastern USA necessitate additional typifications to stabilize the taxonomy. Galactia purshii is lectotypified here as the earliest available but overlooked name for a fairly common species of the Atlantic Coast and peninsular Florida. Galactia volubilis is epitypified here since the characterization of the species has been limited by its lectotype being an illustration. A lectotype is designated for Galactia pilosa var. angustifolia, a form with narrow leaves here considered synonymous with G. volubilis.
