  • The term taxa here refers to entities at species level and below
  • The term species refers only to those entities at species rank
  • * The term dicot is here used in its traditional sense to retain compatibility with previous tables and for ease of use. ‘Dicotyledons’ is now strictly a paraphyletic assemblage of the Nymphaeales, ‘magnoliids’ and ‘eudicot’ clades (cf. New Systematic Sequence)

Compiler’s Note

While the current contents are manual concatenations of census data, or static tables drawn from recent published works, it is intended that future versions of this page will contain live flora statistics drawn directly from the constantly maintained datasets held at the Western Australian Herbarium. At that time we would also seek to disseminate the standard logic behind the accurate calculation of these statistics. In this way, not only will the latest figures be available at all times, but the correct methodology for calculating and applying those figures will become better understood.

Did you notice?

There is a diminishing relationship between figures in subsequent rows of the table, as figures in each category are subtracted from the ones above. For example: in each column: A − B = C.

Highlighted rows

Highlighted rows are the recommended figures if you need:

  • to cite the actual number of known entities in WA (D), or
  • a conservative estimate of the number of well-documented species (H).
