Floristic Regions - Floristic Kingdoms

Floristic Kingdoms

Botanist Ronald Good identified six floristic kingdoms (Boreal or Holarctic, Neotropical, Paleotropical, South African, Australian, and Antarctic), the largest natural units he determined for flowering plants. Good's six kingdoms are subdivided into smaller units, called provinces. The Paleotropical kingdom is divided into three subkingdoms, which are each subdivided into floristic provinces. Each of the other five kingdoms are subdivided directly into provinces. There is a total of 37 floristic provinces. Almost all provinces are further subdivided into floristic regions.
