'aloaceous' originates from New Latin, formed from the botanical name 'Aloe' (from Greek 'aloē') plus the Latin-derived suffix '-aceous', where 'Aloe' referred to the plant (from Greek ἀλόη) and '-aceous' meant 'of the nature of, pertaining to'.

'aloaceous' developed from the botanical/New Latin formation using 'Aloe' (from Greek 'aloē'), combined with Latin '-āceus'/'-aceous' to create an English adjective meaning 'having the nature of Aloe'; this formation entered scientific and descriptive English usage.

Initially it denoted a direct relation to the genus Aloe (botanical use), and it has retained that basic meaning while also being used more generally to describe aloe-like characteristics (e.g., succulent leaves).
