'anomaliflorous' originates from a New Latin/Neo-Latin formation combining Greek 'anomalos' (meaning 'uneven, irregular') and Latin 'flōrus'/'flōrus' derived from 'flōs' (meaning 'flower'), where the elements together indicate 'flowered in an irregular way'.

'anomalos' (Greek) + Latin root 'flōs' produced New Latin/Neo-Latin coinages such as 'anomaliflorus' used in botanical Latin; this then entered modern English as 'anomaliflorous'.

Initially formed to describe 'having irregular or unusual flowers' in botanical descriptions, the meaning has remained consistent and is used chiefly in specialized botanical contexts to denote irregular floral morphology.
