![]() ![]() Both Rafflesia and Amorphophallus are flowering plants, but they are unrelated to each other. īecause Amorphophallus has the world's largest unbranched inflorescence, it is sometimes mistakenly credited as having the world's largest flower. The seeds are packed into berries, which contains hundreds of thousands of seeds. The extremely tiny seeds have extremely tiny elaiosomes, and are thus most likely dispersed by ants. Tree shrews and other forest mammals eat the fruits. Most species are dioecious, having separate male and female flowers, but a few ( R. ![]() The foul odour attracts insects such as carrion flies, which transport pollen from male to female flowers. The flowers look and smell like rotting flesh. In Sapria, the "diaphragm" is a true corona while in Rafflesia the diaphragm is made up of adnate petals to form a dome, the true corona being greatly reduced. In both genera the petals are now described as sepals (or more correctly as "petaloid tepals") instead of vaguely defined "perigon lobes". Charles Davis of Harvard has discovered an important difference between Rafflesia spp. A team of morphologists and geneticists headed by Prof. baletei, has 12 cm (5 in) diameter flowers. A Rafflesia that flowered in West Sumatra in 2019 was measured to be almost 4 feet (120 cm) in diameter, the largest flower ever recorded – 4 inches (10 cm) wider than the flower reported as the largest in 2017. In some species, such as Rafflesia arnoldii, the flower may be over 100 centimetres (40 in) in diameter, and weigh up to 10 kilograms (22 lb). The only part of the plant that can be seen outside the host vine is the five-petalled flower. It is a holoparasite of vines in the genus Tetrastigma (a plant in the Vitaceae, the grape vine family), spreading its absorptive organ, the haustorium, inside the tissue of the vine. Replica Rafflesia displayed in Philippine National Museum ![]() To tell you the truth, had I been alone, and had there been no witnesses, I should, I think, have been fearful of mentioning the dimensions of this flower, so much does it exceed every flower I have seen or heard of. I had ventured some way from the party, when one of the Malay servants came running to me. Here I rejoice to tell you I happened to meet with what I consider as the greatest prodigy of the vegetable world. The following is from Arnold's account of discovering the flower: The flower, and the genus, was later named after Stamford Raffles, the leader of the expedition and the founder of the British colony of Singapore. The first British person to see one was Joseph Arnold in 1818, in the Indonesia rainforest in Bengkulu, Sumatra, after a Malay servant working for him discovered a flower and pointed it out to him. Western Europeans first learned about plants of this genus from French surgeon and naturalist Louis Deschamps when he was in Java between 17 but his notes and illustrations, seized by the British in 1803, were not available to western science until 1861. Plants of the World Online lists up to 41 species from this genus, all of them are found throughout Southeast Asia. The species have enormous flowers, the buds rising from the ground or directly from the lower stems of their host plants one species has the largest flower in the world. Rafflesia ( / r ə ˈ f l iː z( i) ə, - ˈ f l iː ʒ( i) ə, r æ-/) is a genus of parasitic flowering plants in the family Rafflesiaceae. ![]()
