When the flowers are ready for pollination, the spadix heats up and emits a nauseating smell. This stench is so bad that the Indonesians call the plant ‘the corpse flower’. Analyses of chemicals released by the spadix show the “stench” includes dimethyl trisulfide (like limburger cheese), dimethyl disulfide, trimethylamine (rotting fish), isovaleric acid (sweaty socks), benzyl alcohol (sweet floral scent), phenol (like Chloraseptic), and indole (like human faeces). The inflorescence rises from a tuber, a swollen underground stem modified to store food for the plant. This tuber, more or less spherical in shape and weighing 70 kg or more, is the largest such structure known in the plant kingdom.
