Of or belonging to the plant family Balsaminaceae; having characteristics of plants in the touch-me-not family.
From 'balsamin-' (relating to Balsaminaceae) plus the suffix '-aceous' (denoting relation). This botanical adjective emerged in 19th-century plant classification systems.
When botanists say a plant is 'balsaminaceous,' they're using Latin taxonomy to convey membership in a family—it's a shorthand that connects the plant to hundreds of related species without saying their full names.
