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,
Rafflesia verrucosa the plant. "Rafflesia verrucosa" has very distinctive raised warts on its perigone lobes and diaphragm. The warts are non-uniform in shape or size. The warts extend to the diaphragm rim of the plant; this characteristic is unique to "R. verrucosa", while all other "Rafflesia" species lack warts on their diaphragms. Another unique characteristic of "R. verrucosa" is the anastomosing plate-like processes on the plants disk. The hair like ramenta are longer (7 mm) when compared to other small "Rafflesia". Compared to other smaller-sized "Rafflesia", the anther number of "R. verrucosa" is much greater (20-21). The anthers size and disk size
