'anthogenous' originates from Greek, specifically the word 'anthogenēs', where 'anthos' meant 'flower' and '-genēs' meant 'born' or 'produced'.

'anthogenous' changed from the Greek word 'anthogenēs' through Late Latin/Medieval Latin forms (e.g. 'anthogenus') and eventually became the modern English word 'anthogenous'.

Initially, it meant 'born of or produced by flowers', and over time it has retained this core sense as 'originating from flowers' in modern usage.
