Data from: Efficient pollination stinks: Corpse flowers use floral trapping and persistent emissions

Flowering corpse plants attract pollinating carrion insects through
pungent, nocturnal odors. Female flowers primarily emit organosulfur,
including ~12gS/hour as methanethiol with mixing ratios comparable to
landfills; male emissions are smaller and more diverse. Floral emissions
during blooming represent ~0.4% of plant biomass and change throughout the
blooming sequence, consistent with floral trapping: insects remain with
florets after initial attraction for subsequent release with pollen
shedding the following night, preventing inbreeding and enhancing
fertilization efficiency. Female flower plumes are resilient under
pristine conditions, with relative floral composition changing minimally
with nighttime oxidation and attracting insects for later release during
the male bloom stage, which is less resilient. In polluted atmospheres,
rapid oxidation may impact compound ratios and plume size, inhibiting
pollination of these endangered plants.
