Taxonomical breakdown for plants based on the Linnaean system of classification:

Kingdom == PLANTAE

Division (equivalent to Phylum) == suffix -phyta

Class == either Dicotyledones or Monocotyledones

Subclass == suffix -idae

Order == suffix -ales

Family == suffix -aceae

Genus == suffix varies

Species == suffix varies

a mnemonic that worked well for me was 'KiPCOFGS' it sounds funny so it may be memorable for you too.
