Each flower produces just one seed which can only germinate if it succeeds in lodging itself in the tissue of the Tetratigma vine, which creeps around the rainforest floors. Hence, the Rafflesia is usually floor-bound, feeding from the vine by extending thread like filaments into its tissue. Ecologists theories that animals like wild boars which roam the forests pick up the Rafflesia seed on their hooves and implant it into the tissue of Tetrastigma vine.
The best place to view this floral wonder is the Gunung Gading Forest Reserve in the Lundu district. Along the designated trails are a few Rafflesia sites where one can see the flower in the various budding, full bloom and post-bloom stages. The Forest Reserve provides local guides to bring visitors to these sites for a small fee. According to these guides, the best time to see it in full bloomis during the rainy season.
