Rafflesia

Rafflesia is a genus of parasitic flowering plants. He was found in the rainforest of Indonesia by a guide from Indonesia who works for Dr. Joseph Arnold in 1818, and named after Thomas Stamford Raffles, the leader of the expedition. it consists of approximately 27 species (including four that are not yet fully known to its characteristics as recognized by Meijer 1997), all of its species found in Southeast Asia, on the Malay Peninsula, Borneo, Sumatra and the Philippines. this plant has no stems, leaves or roots that really. Rafflesia is an endoparasite in the vines of the Tetrastigma genus (Vitaceae family), spreading its root-like haustorium within the vascular tissue. the only part of the Rafflesia plant that can be seen outside its host plant is a five-crowned flower. In some species, such as Rafflesia arnoldii, the diameter of the flowers may be more than 100 cm, and weigh up to 10 kg
