Belonging to or resembling plants in the garlic and onion family, especially having their characteristic pungent smell or taste.
From Latin 'allium' (garlic) + '-aceous' (pertaining to or resembling). The suffix '-aceous' comes from Latin and creates adjectives from botanical family names.
Alliaceous plants contain sulfur compounds that are nearly identical across the entire family—this is why garlic, onion, and leek all make you cry in different ways, as they're all burning the same chemicals into the air.
