Getting to grips with botanical Latin

Botanical Latin is used to organise plants using a system of taxonomy, this is just putting plants into groups based on their similarities.
Often, these similarities are due to the process of evolution, with similar plants evolving together and thus having similar characteristics like flower appearance, leaf shape or growth habit.

Species

The most specific category, species talks about a particular plant.

Then, genus

Genus is a grouping of similar species and these two names together are the most frequently used terms to describe plants. For example the species, Sedum moganianum is in the genus Sedum.
You can recognise these Latin names as they are typically italicised or underlined to denote Latin, the genus is always capitalised and the species is not.

Family groupings come next

Then order, class, phylum and finally kingdom.
Kingdom is the widest category, dividing all living organisms into the broad labels: animals, plants, fungi, single-celled organisms called protists and two different types of bacteria.

The biggest worry

Most people worry about the correct pronunciation of complex looking botanical names, in reality, there is no correct way to say them!
Botanical Latin is a non-spoken language with no single consistent pronunciation system.
It's not even a true language, rather it's a written system of naming developed by the infamous Carl von Linne, known simply as Linnaeus. It is his name that is commonly given after a species, denoted by L. because he’s just that famous. He has named most of the plants we recognise today.

Some advice

If I could give some advice, its to just have a go!
Having a go and completely botching the Latin name is much more useful and informative for communicating about plants than using imprecise common names. This is because common names are frequently shared across different, sometimes completely unrelated groups of plants.

Unrelated groups of plants

For example, species in the genus Pelargonium are mostly frost-tender, evergreen species which are commonly called geraniums.
But Geranium is also a separate genus containing hardy, herbaceous plants.
When the common name geranium is applied to both genera, you can see how confusion arises!
These two were once all categorised in the genus Geranium based on their appearance and both fall into the same higher groupings of family, order and kingdom. Now with scientific advances, particularly in the field of genetics, we can order species much more precisely, based on many many more criteria than simply what they look like.
These categories are always under examination and prone to changing as technology gets more advanced.

An encyclopedia in a name

I think one of the best things about botanical Latin names is the information they can give you.
They aren’t just arbitrary labels put to plants, Latin names contain a whole wealth of detailed information such as flower colour, growth habit, habitat preferences and flowering time. If you know how to read it!

Latin can tell you what a plant looks like:

  • Roseus translates to rosy-pink
  • Albus to white
  • Nigrum to black
  • Rubrum to red
  • Flavus to yellow
  • Argenteus to silver
  • Aureus to gold
  • Variegatus indicates variegation

Latin can tell you what a plant grows like:

  • Gracilis is a term for graceful, seeing this in a plant name informs you that the plant in question is a slender, graceful specimen.
  • Pyramidalis denotes a pyramid shape
  • Columnaris means columnular
  • Repens translates to creeping, indicating a creeping growth habit
  • Scandens indicates a climbing species
Pelargonium

Latin can tell you where a plant has come from:

  • Species denoted with alpinus are usually found above the treeline
  • Aquaticus species tend to live in water
  • Saxatilis indicates a rocky environment
  • Palustris indicates a wet, swampy or marshy environment

Latin can also tell you when a plant may flower:

  • Vernalis; spring
  • Aestivalis; summer
  • Autumnalis; autumn
  • Hyemalis; winter
