Rafflesia (/ r ə ˈ f l iː z (i) ə,-ˈ f l iː ʒ (i) ə, r æ-/), [2] or stinking corpse lily, [3] is a genus of parasitic flowering plants in the family Rafflesiaceae. [4] The species have enormous flowers, the buds rising from the ground or directly from the lower stems of their host plants; one species has the largest flower in the world.
The buds take many months to develop and the flower lasts for just a few days. The flowers are dioecious – either male or female, thus both flowers are needed for successful pollination. [22] When Rafflesia is ready to reproduce, a tiny bud forms outside the root or stem of its host and develops over a period of a year. The cabbage-like head ...
