For the purposes of this category, "Pacific" is defined in accordance with the
World Geographical Scheme for Recording Plant Distributions (WGSRPD), in which it is considered one of nine botanical
continents (Europe, Africa, Asia-Temperate, Asia-Tropical, Australasia, Pacific, Northern America, Southern America, Antarctic).
It includes flora taxa that are
native to, or
naturalised in, the Pacific region. Taxa that are introduced but not naturalised are excluded. Taxa of the lowest rank are always included. Higher taxa are included only if
endemic.
