Compare -aceous suffix and the foreign-language suffixes cited at that entry.Attested in scientific taxonomical terms from at least the first half of the 19th cent. Combining with first elements ultimately of Latin and Greek origin. The ending -acean is earlier found in a number of adjectives formed with -an suffix on Latin adjectives in -aceus (see -aceous suffix), e.g. relollacean adj., lappacean adj., sebacean adj., violacean adj.
