Rafflesia arnoldii which then pollinate the rare plant. It is not to be confused with the titan arum, "Amorphophallus titanum", which is also commonly referred to as the "corpse flower" because of its repulsive odor. "Rafflesia arnoldii" is rare and fairly hard to locate. It is especially difficult to locate the flower in forests, as the buds take many months to develop and the flower lasts for just a few days. The flowers are unisexual and thus proximity of male and female flowers is vital for successful pollination. These factors make successful pollination a rare event. When "Rafflesia" is ready to reproduce,
Tetrastigma Tetrastigma Tetrastigma is a genus of plants in the grape family, Vitaceae. The plants are lianas that climb with tendrils and have palmately compound leaves. The species are found in subtropical and tropical regions of Asia, Malaysia, and Australia, where they grow in primary rainforest, gallery forest and monsoon forest and moister woodland. Species of this genus are notable as being the sole hosts of parasitic plants in the family Rafflesiaceae, one of which, "Rafflesia arnoldii", produces the largest single flower in the world. Within the Vitaceae, "Tetrastigma" is most closely related to "Cayratia" and "Cyphostemma". A fossil seed fragment
