Eastern Asia (WGSRPD)

[2] The WGSRPD is a biogeographical system developed by the international Biodiversity Information Standards (TDWG) organization.

[3] The system provides clear definitions and codes for recording plant distributions at four scales or levels, from "botanical continents" down to parts of large countries.

[5] Organizations and works using the scheme include the International Union for Conservation of Nature (IUCN),[6] the Germplasm Resources Information Network (GRIN), and the World Checklist of Selected Plant Families (WCSP).

[7] For example, the entry for Lilium concolor in the WCSP includes the numerical codes "30 31 36 37 38",[8] the initial "3" showing these are all regions of Asia-Temperate, with "38" being Eastern Asia.

The Volcano Islands (Kazan-retto) and the Bonin Islands (Ogasawara-shoto) were moved from the Pacific botanical continent to Eastern Asia within Asia-Temperate as they have many endemic plants in common with Eastern Asia.
