Botanical Latin Lexicon
A Beginners guide to common Botanical Latin.
An understanding or even a passing familiarity with Botanical Latin can give many useful clues about a plant’s discoverer, breeder, geographic source, originating nursery, appearance, or growing style. But many gardeners find it understandably very scary, especially when it comes to pronunciation.
There are two bits of information that demystified and opened up my personal exploration of the subject. Firstly, it is not an actual living, spoken language; it’s a kind of hybrid descriptive language made mainly of Latin, partly of Greek, and includes some made-up words that have been tweaked to fit the format. Secondly, and because of ‘firstly’ there is no actual authority on pronunciation, everyone just does their best and sounds a bit uncertain doing it. Usually if you are anywhere close people know which exact plant you are referring to…which is the whole point.
Biology and biological description are a bit more exacting than this though and often there is only the correct, Latin based name for particular part of a plant, or animal. As a gardener you may not need to trouble with this but if you get interested in citizen science and recording the plants around you, you will need to tackle this to work with identification keys. This section is my non-exhaustive beginners reference guide to the Latin, Botanical terminology is covered under the “Botany underlying Plant Descriptions” portion of our “Description, Classification & Botany” Page, and links to further reading are at the foot of this page.
General Rules and Tips
Latin Declensions
Like many of its derivative languages Latin nouns have variations depending on their Grammatical Case, number, or more usually, gender, they are either masculine, feminine or neuter. These are known as declensions. Adjectives used to describe nouns must have a matching gender. A lot of this is a bit complex to go into here.
The general rule here is that…
- Feminine nouns / adjectives have the ending “-a”,
- Masculine nouns / adjectives have the ending “-us”,
- Neuter nouns / adjectives have the ending “-um”,
- These suffixes are sometimes preceded by “i” so “-ia”, “-ius”, “-ium”,
- Sometimes the Greek bases of “-os” or “-on” replaces the Latin “-us” or “-um”.
These gender rules give rise to little families of suffixes or word endings. Here are some of the most commonly occurring and some pronunciations which include some exceptions. There are more exceptions, but you will pick these up as you go.
1st Declension, mostly Feminine, with some Masculine exceptions
2nd Declension, mostly Masculine with some Feminine exceptions.
2nd Declension, Neuter
3rd Declension, Feminine & Masculine.
3rd Declension, Neuter

Vowels & Syllables
Each vowel must be in a separate syllable (apart from the diphthongs ai, eu, oi and ou. This is really handy as pronunciation depends on breaking words down to their syllables.
If there are two syllables the emphasis is on the first. If there are more than two syllables and the second-to -last one is long it has the emphasis, if the second-to -last one is short the syllable before it has the emphasis.
Vowel pronunciation
A, as in part.
E, as in pet, or as in hey.
I, as in pit, or as in machine, at the beginning of a syllable as y as in , as in yard, between vowels becomes “i-y”.
O, as in port, or as in post.
U, as in put, or as in true. When after g, s or at the beginning of a syllable as w as in wine.
Consonants & Pronunciation
B, d, f, h, l, m, n, p, q, r, t, x and z are all pronounced as in English. . Of the remaining…
C or K , is always K, as in sky.
G, is always as in good, but before n as ng then as in sing.
L, is as in bowl, unless doubled before an “i” then as in link.
N, as in man, before c, g or x as in sing.
QU, as in squint.
S, as in say.
T, as in stay.
X, as c+s as in Axe.
J, W & Z do not occur.
Derivations from Proper Names
Most of the times you see this the name will be derived from the name of the person who discovered the plant (as modern western botany sees it anyhow!)
- The ending -ii is used for a male discoverer or developer.,
- The ending -iae is used for a female discoverer or developer.
- The ending -iana commemorates the attached personal name.
