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⁾

The Nepenthes Tenax, which is considered one of the world's uncommon plants, is one of the oddest-looking plants. This plant, which has many similarities with the pitcher plant, can reach a height of 100 cm and has a pitcher-shaped flower on top that grows to a height of 15 cm. This is a very rare Australian lowland plant that can only be found in northern Queensland. ³⁾

One of the world's longest-living plants, also known as the living fossil plant, is also one of Africa's rarest plant species. The trunk of this strange-looking plant is woody, dense, short, and stout. This plant has a slow growth rate and is thought to live on Earth for 1000 to 2000 years. ⁴⁾
