Linnaean classification

Plants can be divided into eleven divisions, according to basic factors such as methods of reproduction, energy sources, and physical structure (see Table 4.1). The division is a modification of the Linnaean classification system, being between kingdom and phylum.

Carolus Linnaeus (1707-78) published his book Species Plantarum in 1753 and started the science of taxonomy of plants as well as animals. Linnaean taxonomy, which remains the basis of modern classification, relies upon structure (morphology) and function. The close relationship between horses and zebras is quite clear to any observer. On the other hand, a new observer (a scientist from another planet ) would almost... 

Armed with a new research infrastructure, it is not too ambitious to aim to discover and describe most, say 80 per cent, of Earth s species within an intense period of planetary exploration, say 50 years. Such a 50-year inventory would not be an end, but a beginning - an effort to triage evidence of as many species, clades and components of ecosystems as possible for the benefit of scientists, including taxonomists, of tomorrow. Even if aU species could be documented, an unrealistic but laudable goal, the need to sample and collect reanalyze apply new theories, methods and tools and test and refine taxonomic concepts and Linnaean names and classifications would continue indefinitely.
