Providing names is of fundamental importance for biology because names enable us to communicate and exchange information about organisms. In fact, in the absence of names, biology has nothing to work with, the taxa for this purpose in fact do not exist. Names therefore are not merely tags or labels, rather they are the principal ‘hooks’ by which information about an organism is stored and retrieved. If taxa are poorly defined, or if the names applied to them are incorrect, then the information that is assembled and disseminated is likely to be wrong, or at least its value will be diminished.
It is for these reasons that it is imperative that organisms be accurately named.
Taxonomic keys are the principal means of identifying, or naming, organisms, and there are two basic types of keys:
Conventional dichotomous keys that are normally produced as printed copy.
Interactive multi-access keys that are produced via an electronic medium.
The quickest and most reliable way of naming an Australian Acacia is to use the electronic WATTLE key (see Australia below). It is important to remember, however, that successful use of any key usually requires experience with it and the length of time required to gain such experience is related to factors such as the number of taxa included in the key (most relevant for conventional dichotomous keys), the terminology used and the way the key itself is constructed and functions.
Identification keys for Australian species of Acacia (selected references).
Note: It is expected that future developments of WorldWideWattle will include an on-line identification tool for Australian Acacias.
Australian Biological Resources Study — Visit this site, click on ‘Search database’ and enter Acacia to obtain the key to species and then the descriptions (prepared by a range of authors) and illustrations of Acacia that appeared in the Flora of Australia vols. 11A and 11B. (These volumes are available for purchase from CSIRO Publishing.). Note: these same descriptions are available (in a different format) from under Species Gallery on Worldwidewattle.
