'equal-fruited' originates from English, formed as a compound of 'equal' and 'fruited'. 'equal' ultimately comes from Latin 'aequalis' (via Old French/Middle English) where 'aequus' meant 'level, even'; 'fruit' comes from Latin 'fructus' (via Old French) meaning 'produce, enjoyment'.

'equal' moved from Latin 'aequalis' into Old French and Middle English as 'equal', and 'fruit' came from Latin 'fructus' through Old French 'fruit'; the adjective form 'fruited' and the compound 'equal-fruited' developed in Modern English, especially in botanical usage.

Initially, the components meant 'level/even' (equal) and 'produce' (fruit); over time they combined to form the descriptive botanical adjective 'equal-fruited', meaning 'having fruits of equal size or development'.
