Botanical Latin Glossary

a project of
V. F. Thomas Co. - P. O. Box 111 - Shawmut, Maine  04975

(updated 9 January 2021)

This glossary contains words from descriptions and diagnoses of new (at the time) taxa. Its purpose is to provide (1) a list of words used in botanical Latin and (2) forms of those words found in the literature.

Words in bold face and flush with the left margin are the main entries that are found in Latin dictionaries. Indented words in “normal” face are forms found in the literature. Descriptions of species named in parentheses contain the preceding word form. In some cases, the scientific name is a link to the original description and a translation of it.

Thank you to Tom Hayward, lecturer emeritus in Classical and Medieval Studies at Bates College (Lewiston, Maine), for his help when I find myself struggling with a translation. In the end, however, I accept responsibility for any errors in this glossary or in the associated translations unless I can find some way to blame them on Tom (or on anyone else). Comments and corrections are welcome and should be e-mailed to or sent to the address at the top of this page. Thanks.
