Rafflesia Park where the flowers are numbered and monitored by the park rangers. "Rafflesia" are also remarkable for showing a large horizontal transfer of genes from their host plants. This is well known among bacteria, but not higher organisms. The name "corpse flower" applied to "Rafflesia" can be confusing because this common name also refers to the titan arum ("Amorphophallus titanum") of the family Araceae. Moreover, because "Amorphophallus" has the world's largest unbranched inflorescence, it is sometimes mistakenly credited as having the world's largest flower. Both "Rafflesia" and "Amorphophallus" are flowering plants, but they are only distantly related. "Rafflesia arnoldii" has
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
