The purpose of these botanical Latin lessons is to help you translate descriptions and diagnoses of taxa (usually species but also genera) found in the literature. If you are already familiar with classical Latin, much of the content of these lessons will be review. However, due to the nature of botanical Latin, these lessons will not be sufficient for learning classical Latin, but they will give you a good introduction to understanding nouns, adjectives, adverbs, prepositions, and participles in classical Latin.

There is a lot of text to read in these lessons, and you are encouraged to take your time reading it. There is no need to rush through any lesson. If you find anything not explained sufficiently and/or confusing, please let me know. My contact information is at the top of each page in this sequence of lessons.

A companion to these lessons is a complete concordance of words used by Linnaeus in his diagnoses of species of higher vascular plants (pages 1–1140 and 1187–1200) in his two-volume 1753 Species Plantarum. (Words and their forms from pages 1141–1186 will be added, probably during the summer of 2024.) This concordance includes not only the form of each word as it appears as a main entry in a dictionary but also the various forms of each word used in Linnaeus’s diagnoses. As much as possible, the examples, vocabulary, and exercises in these lessons use words from Species Plantarum.

I hope they will be helpful to you.
