Before establishment of binomial nomenclature,
the names of organisms consisted of many
words. These words were based on the
characters of these plants or animals. In different
countries, even in different parts of same country;
local names were used for plants and animals.
The same organism may be given different names
e.g. turnip, shaljam, gongloo, thipar, and gogroon
are all names of same plant. In England, there are
at least fifty names for pansy. Similarly a single
common name may be used for different kind of
organisms e.g. the word “raspberry” is used for
about 100 kinds of plants. This confusion can be
avoided by giving each organism a scientific
name according to binomial nomenclature
proposed by Carolous Linnaeus in 1753. It is
adopted by all taxonomists.
Before Linnaeus came along and simplified things, plants usually had many long descriptive Latin names, making learning and memorizing them very difficult. The names were also changed based on the will of the botanist describing the plant. There weren’t universal names for each plant, so people around the world couldn’t be certain that they were talking about the same plants.

Once the plants had been given specific names, many benefits were seen.

1. Clarification – each plant had a unique name that was specific to that plant.
2. Universal – everyone used the same name to identify the specific plant.
3. Education – plant names were easier to remember and to learn.
4. Classification – plants were more easily categorized and the categories easier to understand.
