- Antarctic Floristic Kingdom
.
According to Ronald Good, about 50 genera of vascular plants are common in the Antarctic plant kingdom, including "
Nothofagus " and "Dicksonia ". Takhtajan also made note of hundreds of other vascular plant genera scattered about and isolated on islands of the Southern Ocean, including "Calandrinia feltonii" of the Falkland Islands, "Pringlea antiscorbutica" of the Kerguelen Islands, and themegaherb genera of the New Zealand Sub-Antarctic Islands.According to Takhtajan, 11
families are endemic to this kingdom:Lactoridaceae ,Gomortegaceae ,Hectorellaceae ,Halophytaceae ,Francoaceae ,Aextoxicaceae ,Tribelaceae ,Griseliniaceae ,Misodendraceae ,Alseuosmiaceae andDonatiaceae .ubdivisions
The Antarctic floristic kingdom is subdivided into four floristic regions, and subdivided even further into sixteen
floristic province s. Most of the provinces lie within, or very near theAntarctic convergence zone.Fernandezian Region
(often included within the
Neotropical Kingdom ) Endemic family:Lactoridaceae ; endemic genera: 20, includingThyrsopteris ,Nothomyrcia ,Selkirkia ,Cuminia ,Robinsonia ,Rhetinodendron ,Symphyochaeta ,Centaurodendron ,Yunquea ,Hesperogreigia ,Podophorus ,Pantathera andMegalachne .
