Numerical taxonomic studies of the genus Notholca

  title={Numerical taxonomic studies of the genus Notholca},
  author={Thomas Nogrady and Robert Lee Wallace},
The genus Notholca has been subjected to taxonomic analysis, using cluster analysis and ordination by principal coordinates analysis, based on 67 phenetic characters. All analyses converge on essentially identical groupings, but fail to inject new hypotheses to remedy the confusing and overlapping taxonomy of the genus. This shortcoming is ascribed to the incompleteness of the character set which currently lacks biochemical and genetic parameters. We suggest to invalidate the subspecies' of N… CONTINUE READING
