Summary
Included here is the Pacific zone of Micronesia comprising the Caroline Islands (including Palau and Pohnpei), Mariana Islands (including Guam), Marshall Islands, Gilbert Islands, Ellice Islands, Phoenix Islands, Tokelau Islands, Baker Island, Banaba Island, Howland Island, Nauru Island and Wake Island.
Of the endemic vascular plants so far recorded there are about 390 species in 175 genera and 66 families. There is one endemic genus (marked red) but no endemic families. This list has recently been revised by Costion & Lorence (2012) and their study shows that Micronesia contains a higher percentage of endemic plant species per square kilometre than the Hawaiian archipelago.
