Acuña-Castillo, R., J. E. Jiménez, L. E. Bezerra-Silva., J. San Gil-León & M. A. Blanco. 2021. Notes on the distribution of Brasenia schreberi (Cabombaceae) in the Neotropics, with a new country record for Costa Rica. Darwiniana, nueva serie 9(2): 364-374.

We studied herbarium specimens of Brasenia schreberi from the Neotropics in order to describe the distribution pattern of the species across the region. Also, we report the first records of B. schreberi for Costa Rica. We confirm that B. schreberi has a sporadic pattern of distribution in the region and also in most neotropical countries where it has been collected. For this reason and because of its apparent disappearance from some localities, we recommend B. schreberi to be considered Vulnerable in the Neotropics.
