'angular-fruited' originates from English, combining the adjective 'angular' (from Latin 'angularis' / 'angulus' meaning 'angle') and the past-participial adjective-forming use of 'fruit' (from Latin 'fructus' meaning 'fruit').

'angular' derives from Latin 'angulus' ('angle') via Old French/Medieval Latin forms and entered Middle English as 'angular'; 'fruit' comes from Latin 'fructus' through Old French 'fruit'. The compound 'angular-fruited' is a modern English botanical compound formed by joining the descriptive adjective and 'fruited' to specify fruit shape.

Initially the component words meant 'angle' and 'fruit' respectively; over time the compound came to be used specifically in botanical description to mean 'having fruits with pronounced angles or ridges'.
