Data sourced on 1st June 2013. Compare with the 2012 figures.
The terms taxa here refers to entities at species level and below; and species refers only to those entities at species rank.
A - total number of vascular plant names in the database
B - number of synonymous, excluded or misapplied names (ie. plant names no longer in current use, at least in WA)
C - number of currently accepted plant names (ie. includes the species-level name when infra-species exist)
D - number of currently accepted taxa (ie. excludes the species-level name when infra-species of that taxon exist)
E - number of currently accepted species (ie. only the species-level names, excludes any infra-species names)
F - number of proposed but unpublished taxa (ie. informal names proposed on specimens or in manuscripts)
G - number of assigned but unpublished taxa (ie. informal names assigned to specimens for further analysis)
H - number of formally published species names (ie. formally published names described in botanical literature)
I - number of published naturalised alien species (ie. formally published names of weed species occurring in WA)
J - number of published species native to Western Australia (ie. formally published names of native WA species)
K - number of species with subordinate current taxa (subspecies, varieties and formas).
L - number of current names recorded in the Census denoting taxa which are named hybrids or un-named hybrid formulae.
For the vascular plants, a brief comparison of the 2013 data with 2012 data shows:
Data sourced on Friday, 7 June 2013. Other core statistics often required for citation in various works include the number of:
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.

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

For those familiar with Green, J.W. (1985) Census of the vascular plants of Western Australia 2nd ed., WA Herbarium, Perth and subsequent supplements, the following four PDF tables are presented in the style of Green's statistical summaries. They provide further details corresponding to row H in the above table. Data also sourced on 1st June 2012.
