They can be found on the Malay Peninsula, Borneo, Sumatra, Thailand, and the Philippines in Southeast Asia. They are the world's largest single flower. The flowers of one species can grow to be over a meter (three feet) long. Flies are drawn to the flowers because they smell like a dead animal. When the flies get inside, they pollinate the Rafflesia, which they usually lay their eggs on rotten flesh. ¹⁾

The Encephalartos Woodii, one of the world's rarest plants, is now conserved and confined to the botanical garden where it was transported from Zululand. This plant is native to South Africa and is thought to be extinct in the wild, with all specimens being clones. Its cycad variety had both male and female plants, but no female plants are to be found. As a result, there will be no more propagation, and the male plant will be preserved. ²⁾
