SOUTH FLORIDA Native Status: Native

South Florida History and Distribution: This was reported as possibly extirpated in South Florida in Gann et al. (2002; pp 141-142), based on herbarium specimens collected from the early to mid-1800s to 1948 in the Florida Keys, and a single collection in 1982 from Big Cypress National Preserve on the Monroe County mainland (Black and Black s.n. FTG). A new collection in South Florida was made in 2016 by Keith Bradley in Collier County in a roadside ditch near Immokalee (4002 USF); this discovery has also been reported on iNaturalist. George Wilder and Jean McCollom (2018) reported Echinodorus berteroi at Corkscrew Swamp Sanctuary based on their specimen collected between October 2015 and October 2017 (39496 SWF). In December 2017, Randy Mears made a collection nearby in Lee County at the junction of Corkscrew Road and Alico Road east of I-75 (s.n. USF). This is an extremely rare plant in Florida and the southeastern United States, and should be assessed for listing by the State of Florida and FNAI.
