Table of standard geographical codes for plant distributions to be used in botanical databases. (NOTE: region code "00" and botanical country code "00-CUL" have been added to facilitate the inclusion of "cultivated plants in general" and "plants known only from cultivation", respectively. They do NOT form part of the TDWG standard.)
