Atlantic and Gulf Coastal Plain BioProvince

This BioProvince (as defined by Armen Takhtajan) comprises the Atlantic and Gulf states of the United States from New Jersey to Florida and west to southeastern Texas. The coastal plain is largely composed of sedimentary rocks mainly based on Late Cretaceous to Holocene deposits.  The climate is equable with small to moderate annual temperature fluctuations while rainfall is abundant and well distributed throughout the year. The area includes a number of endemic genera and hundreds of endemic species with over a hundred endemic species just within the Asteraceae. The endemic Leitneria floridana, which occus in scattered locations in Florida, Georgia, Missouri, Arkansas and Texas, was originally treated as the only species in the family Leitneriaceae of the order Leitneriales but recent genetic research has placed it in the family Simaroubaceae.

The following accounts for this BioProvince have been written or will be written with particular reference to endemic and locally important species. Accounts available are displayed in green or yellow. Those displayed in red are either in the pipeline or awaiting expert contributions.
