Why might the use of common names to describe organisms sometimes cause confusion?
You might argue that we should just use the so-called "common names" of plants, since it would be much simpler, especially since few people speak Latin. Thus we could all agree that the name for red maple is Red Maple, this would be an English binomial system. However, there are problems with using common names, such as:





"Common names" are often common only to a localized region. The Red Maple is commonly called the Scarlet or Swamp Maple in some areas. The tree Nyssa sylvatica, which is native to the eastern US, has at least four common names (i.e., Sour Gum, Black Gum, Black Tupelo, Pepperidge). In England the white waterlily has 15 common names, and if you include the common German, French, and Dutch names it has over 240 names!


Sometimes the same common name is used in different regions to identify completely different plants. A plant in Georgia called ironweed is of the genus Sidai, whereas in the Midwest ironweed refers to a plant in the genus Vernonia.


Common names usually do not provide information on generic or family relationships, they tend to be independent of other names. In fact common names may suggest erroneous relationships between plants. For example, only one of the following plants is a "true cedar", i.e., of the genus Cedrus: Japanese Cedar (Cryptomeria japonica), Port Orford Cedar (Chamaecyparis lawsoniana), Western Red Cedar (Thuja plicata), Eastern Red Cedar (Juniperus virginiana), and Deodar Cedar (Cedrus deodara).
Reply:Shorter answer (not to undermine): Think about the creature we call "salamander". But in actuality there are scads of different species. What I call a salamander here might very well be a different species of salamander from what you call salamander where you live. Therefore you think I see what you see and I think you see what I see when we don't.
