Rafflesia verrucosa are also both small. One unique morphological feature of "R. verrucosa" is its monoecious or bisexual nature. The only other reported bisexual species in this genus is "Rafflesia baletei". "R. baletei" has male and female flowers that contain vestigial structures of the opposite sex. Further studies will be needed to conclude if the species is a functional bisexual. "Rafflesia verrucosa" has been found only growing on the southeastern slope of Mt.
