Its name comes from the flowers that smell like a rotting carcass, actually intended to invite the beetle and fly pollinators for flowers. Many people often mistake and could not distinguish the dead flowers with "Rafflesia arnoldii" probably because people already know that as the largest flower Rafflesia and then become biased by the size of dead flowers are also great.

After some time (years), it wilted vegetative organs and dormant tubers. If the reserve is adequate food in tubers and supportive environment, majemuknya flowers will appear. If less food reserves to grow back their leaves.
The flowers are very large and high, shaped like a phallus (actually a cob or spadix) surrounded by a sheath of interest which is also large. The flowers married one and protogini: female flowers receptive first, then followed by cooking the male flowers, as a mechanism to prevent self pollination.
