North American Atlantic Region
Encyclopedia
North American Atlantic Region is a floristic region within the Holarctic Kingdom identified by Armen Takhtajan
and Robert F. Thorne, spanning from the Atlantic
and Gulf
coasts to the Great Plains
and comprising a major part of the United States
and southeastern portions of Canada
. It is bordered by the Circumboreal floristic region in the north, by the Rocky Mountain and Madrean floristic regions in the west and by the Caribbean floristic region of the Neotropical Kingdom in the south of Florida
. The flora
of the region comprises two endemic monotypic
families
, Hydrastidaceae and Leitneriaceae, and is characterized by about a hundred of endemic genera
(such as Sanguinaria, Leavenworthia, Gillenia
, Neviusia
, Dionaea, Yeatesia, Pleea). The degree of species
endemism is very high, many species are Tertiary

s, which survived the Wisconsin glaciation
and are now concentrated in the Appalachians (esp. Blue Ridge Mountains
) and the Ozarks. A number of genera (Sarracenia
, Uvularia
etc.) are shared only with the Canadian floristic province of the Circumboreal region. Moreover, as has long been noted (e.g. by Joseph Gerhard Zuccarini
and especially by Asa Gray
), a large number of relict genera (Liriodendron
, Hamamelis, Stewartia etc.) are shared with the relatively distant Eastern Asiatic Region
(comprising Japan
and the east of China
) and sometimes Southeast Asia
. R. F. Thorne counted at least 74 genera restricted to eastern North America
and Asia
(mostly eastern and southeastern Asia). The fossil record indicates that during the Tertiary
period a warm temperate zone extended across much of the Northern Hemisphere
, linking America to Asia.

). Endemism is rather limited in this province, and its boundaries are vague. During the Pleistocene
much of the province was glaciated.
