Summary A second mathematical model describing the species‐area relation was proposed for continuous expanding of sample area. This model is expressed as S =λ ln(1+ x/E ) where S is the number of species occurring in an area x , and λ and E are the constants termed specific diversity and elemental area respectively. As a result of testing the validity of the model for several sets of data, it was shown that the above equation would provide an adequate fit to a group of species belonging to a single synusia which exists in an open habitat. The ecological implications of parameters involved were discussed and the characteristic area presented previously ( Kobayashi , 1974) was defined in terms of E. The relation between results obtained by discrete sampling and continuous sampling was examined and the possibility of converting one to another was suggested.
