Approximate Numerical Summaries 



Numerical summaries should be taken as no more than approximations of local diversity levels. 

 The reasons in favor of this view are numerous: Familial and generic concepts are always 

 somewhat in flux; some taxa treated at the infraspecific level are treated elsewhere as species; all 

 specimens of locally infrequent species may be misidentified; new taxa are being discovered 

 periodically; new state records are made constantly; whether some species are truly naturalized 

 from ornamental plantings may be hard to discern; taxa that were once established have been 

 extirpated later (e.g., Briza spp.); and compilers can easily miscount longer lists. Clayton09 

 notes that inclusion of a taxon for which only one or a few specimens were collected many 

 decades ago, and which has not collected or seen thereafter, inflates the real situation. However.
