VERNACULAR TO BOTANICAL NAME TABLE

VERNACULAR to BOTANICAL to VERNACULAR TABLES

APGIII 2009. E&OE, and as far as can be ascertained, these tables conform to the current APGIII taxonomic system (and if they don't, then your Author should edit them so that they do). But the only ones corrected from AGPII to AGPIII might be for plants growing in Suffolk - in fact, indeed they are. Which means that there are an unknown number still within this table which are still under the AGPII naming system... Who knows which they are.

The taxonomy itself may be subject to revision from time to time, depending upon the current whim of any taxonomists (who sometimes, it seems, cannot decide amongst themselves to which family genera belong). And in any case, taxonomists are continually changing their minds upon the constitution of the tables, with major upheavals and re-appraisals every decade or so.

Note that the tables apply only to representatives of plants which happen to grow in the UK (or have in the last 60 years grown; some may be extinct in the UK now).
