Recent field collecting yielded specimens of Wolffielia lingulata from four different locations in Jalisco, thus the genus may now be considered as part of the flora of Nueva Galicia. In the following list of exsiccata, geographical coordinates and elevations were taken with a global positioning system. All CES numbered specimens were collected under the supervision of W. C. Holmes by the aquatic botany class of the Chapala Ecology Station (CES). The Chapala Ecology Station is operated by the Universidad Autonoma de Guadalajara and Baylor University.
