Strictly speaking, Amorphophallus titanum is not the world's largest
flower. This plant produces a spadix, upon which grow many tiny flowers
(in the true sense of the word). By "flowers" I mean the growths which
contain the reproductive parts of a plant (stamen and pistils).
The largest flower in the world is Rafflesia.
