Answers. Best Answer: Rafflesia is a genus of parasitic flowering plants. Rafflesia plants have no stems, leaves or true roots. They are endoparasites of vines in the genus Tetrastigma (Vitaceae), spreading their absorptive organ, the haustorium, inside the tissue of the vine.The only part of the plant that can be seen outside the host vine is the five-petaled flower.This is NOT a symbiotic relationship. It IS a parasitic relationship.

Most varieties have red flowers and multicolored seeds (though some have white flowers and white seeds), and they are often grown as ornamental plants. The vine can grow to 3 m (9 ft) or more in length. It differs from the common bean (P. vulgaris) in several respects: the cotyledons stay in the ground during germination, and the plant is a perennial vine with tuberous roots (though it is usually treated as an annual).
