The titan arum's inflorescence is not as large as that of the talipot palm, " Corypha umbraculifera ", but the inflorescence of the talipot palm is branched rather than unbranched.

Both " Rafflesia " and " Amorphophallus " are flowering plants, but they are only distantly related . " Rafflesia arnoldii " has the largest " single " flower of any flowering plant, at least in terms of weight . " A . titanum " has the largest " unbranched " inflorescence, while the talipot palm ( " Corypha umbraculifera " ) forms the largest " branched " inflorescence, containing thousands of flowers; the talipot is monocarpic, meaning the individual plants die after flowering.
