Plural of fumitory; a climbing plant with delicate flowers, or archaic rooms used for fumigation.
From Latin 'fumus terrae' (earth's fumes or smoke of the earth), the plant's name referring to its delicate, smoke-like appearance; also used for fumigation chambers.
Fumitory plants are real—they're climbing flowers with translucent petals that actually do look like little wisps of smoke, and medieval herbalists burned them thinking they could cure eye diseases.
