The flower known as the world’s king flower is Rafflesia.

1. Rafflesia is a succulent parasitic herb that originates from the tropical rainforests of Malaysia, Indonesia, Java, and Sumatra. Rafflesia is called Bungapatma locally, which means "a flower as big as a lotus leaf." , which is the largest flower in the world. It is famous for its huge flowers and foul smell, and is known as the "King of Flowers in the World".

2. The largest Rafflesia corolla found so far has a diameter of 1.4m, a weight of 10kg, and a petal thickness of 5cm. It is the largest flower.

3. Rafflesia is a fleshy parasitic herb and not a real "piranha". They have extremely short main axes, no leaves and underground stems, and the nutrient-absorbing organ degenerates into a mycelial shape and invades the host's tissue, so the entire flower is all it has. Almost all the nutrients absorbed from the host supply the growth of the flowers. The flower diameter can reach 3 feet, or 0.9144m, and the highest record can reach 1.4m. The base of Rafflesia is developed from the xylem of the host, and is shaped like a wide-mouthed jar.

4. Rafflesia flower has medicinal value and has the effect of tonifying the kidneys and aphrodisiac. The extract prepared from the flower bud extract is a good medicine for women during childbirth. Indiscriminate harvesting by local people has put Rafflesia in serious danger of extinction.
