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 were found growing from roots that were 7 cm. under soil. In the area it was found, the spatial density of "R. verrucosa" was around 7-8 flower clusters per hectare. The peak flowering season is likely through October to December, but flowering might persist intermittently year round. The reproductive style of "R. verrucosa" is probably similar to other "Rafflesia" species. The impact of various mammals on the herbivory and dispersal is unknown. Trapping around "verrucosa" flower clusters revealed several small mammal species including gymnures, shrews, tree shrews, shrew-mice, moss mice, tree mice, forest mice, the large Mindanao forest rat and
