FDA Specifications. See CDER Specifications.
CDER Specifications. Plant Part shall consist of an alphabetic term which has a maximum length restricted to 100 characters, with the comma and hyphen being the only punctuation permissible. Codes representing these plant and fungi parts shall consist of up to three numbers. A column for the Latin equivalent plant and fungi part has been added to the list of terms. This column will help non-botanists differentiate plant and fungi parts that are written in Latin from the Latin binomial for the genus and species. It will also help users select the correct English translation of that term when only the Latin term is present. However, the plant and fungi part names that are expressed herein in Latin will not become part of either the SPOTS or SRS databases.
