IRC’s Chief Conservation Strategist, George Gann, is a coauthor on a paper recently published in the Journal of the Botanical Research Institute of Texas by Alan S. Weakly et al. titled “New Combinations, Rank Changes, and Nomenclatural and Taxonomic Comments in the Vascular Flora of the Southeastern United States. II” In this paper, Gann and Weakley rename the Florida bristle fern Didymoglossum punctatum subsp. floridanum. This species, formerly known as Trichomanes punctatum subsp. floridanum, was listed as federally Endangered in 2015 and is a species of high conservation concern. To read the paper, click here.
