Typification and nomenclatural notes on four species of Rhynchosia (Leguminosae, Phaseoleae, Cajaninae)

Abstract During revisionary work on the genus Rhynchosia Lour. in India, it was observed that four names need to be typified to stabilize their nomenclatural use. As a result, lectotypes are designated for the four names, namely, Rhynchosia cana (Willd.) DC., R. falconeri Baker, R. filipes Benth., and R. veutina Wight & Arn. The original protologs of these names along with the original herbarium material were evaluated. Nomenclatural remarks discussing the selection of type specimens are given for each name and known isolectotypes are also cited.
