'bacciform' originates from Latin, specifically the word 'bacca', where 'bacca' meant 'berry', combined with the Latin-derived suffix '-form' meaning 'shape'.

'bacciform' was formed in New Latin/botanical Latin as a compound of 'bacca' + '-form-' and entered English in technical/descriptive botanical usage as 'bacciform'.

Initially it meant 'having the form or shape of a berry', and this specific descriptive meaning has remained essentially the same in modern usage.
