This sixth volume of the Flora of Florida collection continues the definitive and comprehensive identification manual to the Sunshine State's 4,000 kinds of native and non-native ferns and fern allies, nonflowering seed plants, and flowering seed plants. Volume VI contains the taxonomic treatments of 19 families of Florida's dicotyledons. Florida has the third most diverse vascular plant flora of any state in the United States, and the Flora of Florida volumes include all indigenous and naturalized taxa currently known to occur within its borders. With keys to family, genus, and species, and with genera and species within each family arranged alphabetically for easy reference, these volumes are the standard reference for botanists, researchers, consultants, and students alike.
