Scientific Classification - The Bogg Mindles

Some are interchangeable; and some have changed over the years so it depends on who wrote the classifications and when...

Yes, there are several 'versions' of the plant classification system. Division/Class are not universally used. Order/Family/Genus/Species are the ones which (I believe) are universal.....but someone else may be along who knows more :-)
