Q

What is the binomial system?

A

Every organism has two Latin names – the name of
its genus followed by the name of its species.

The genus has a capital letter and the species a
small letter. The Genus can be shortened e.g.
Calluna vulgaris can be shortened to C. vulgaris

In typed text, the Latin name is written in italics
and in hand written notes, it is underlined.
