'multiflorous' originates from Latin, specifically the word 'multiflorus', where 'multi-' meant 'many' and 'florus' (from 'flos, floris') meant 'flowered' or 'flower'.

'multiflorous' changed from the Latin word 'multiflorus' and entered modern English via New/Scientific Latin usage, eventually becoming the English adjective 'multiflorous'.

Initially, it meant 'many-flowered', and over time it has retained essentially the same meaning in modern usage.
