Classification and identification

Before going further it is worth pointing out the difference between classification and identification.

Classification answers questions of the sort: How is this bryophyte related to other bryophytes?

Identification answers the question: What's the name of the specimen in front of me?

Classification deals with evolutionary history and a good classification scheme would group evolutionarily close organisms near one another. This demands a good understanding of many different aspects of bryophyte biology since the different aspects provide different types of evidence regarding relationships. In order to develop a sound classification all the evidence must be assessed.

Identification is a fairly mechanical process and you can identify bryophytes without knowing anything about bryophyte classification. You just need to be able to follow the instructions in a bryophyte identification guide. It's a bit like cooking - if you follow the instructions in the recipe you'll bake yourself a delicious cake. You must be able to recognize things such as eggs, flour and milk but you don't need to know the function of any of these ingredients. Of course, a good cook knows what the ingredients do and can then intelligently substitute ingredients or vary the recipe for particular purposes. Similarly, knowledge of bryophyte classification will give you a better grasp of the bryophyte world, allow you to take intelligent shortcuts in identification and help guard against misunderstandings.

The classification hierarchy

All living organisms have been classified in a hierarchical fashion and the intention of a classification scheme is to have the hierarchy reflect the strengths of the evolutionary relationships between different individuals. Individuals that are closely related from an evolutionary perspective are grouped into the one species. Related species are grouped into a genus (plural: genera). Related genera are grouped into a family and, going to still broader groupings (or higher levels of classification), there are orders, classes, divisions (also called phyla, with phylum the singular) and finally kingdoms. This hierarchical scheme immediately tells you that two individuals in the same species are more closely related to each other than two individuals that, while belonging to the same genus, are members of different species. Each of the words given in bold is an example of a taxonomic rank.

In this hierarchical ordering, the number of species is greater than the number of genera, which in turn is greater than the number of families and so on. When a biologist proposes the creation of a new category at one taxonomic rank, he or she must ensure that the new category contains at least one member at each lower rank. For example, a botanist who wishes to define a new order must ensure that within the new order there is at least one family, which in turn must contain at least one genus, which in turn must contain at least one species.

Sometimes categories finer than species are used, and there can be various categories that are intermediate between the levels that have just been given in bold, for example, subclass (which lies between order and class). However, while they are relevant to a specialist, generally they will be ignored here since they merely introduce technical complexities but illustrate no additional classificatory principles.

What about bryophytes? Bryophytes are plants. Hence, at the highest level bryophytes belong to the Plant Kingdom. Bryophytes are distinguished from other plants by being classified in their own divisions or phyla. For example, the liverworts constitute the division or phylum given the name Marchantiophyta. Some other examples of divisions or phyla in the Plant Kingdom are Magnoliophyta (the flowering plants), Pinophyta (the conifers) and Pteridophyta (ferns and horsetails).

Classification

Liverwort vs flowerning plants

For the purpose of illustration here is a classification of the New Zealand leafy liverwort Leiomitra lanata with those of Acacia pycnantha (Australia's national flower, the Golden Wattle) and the grass Themeda triandra (Kangaroo Grass) given for comparison.

There is classification of different types of organisms based on the common characteristics and the differences.

Explanation:

the biggest classification is the classification of the different five kingdoms.this is followed by the phylum. In case of animal kingdom there is usually 10 different phylum. This is followed by the the order.
Then comes the class. following class there is the genera. Each of the genera is further divided into the different organisms on the species. This helps in the easiest study of the different organisms.
