Plant
Rafflesia arnoldii is a plant of the genus Rafflesia. The plant is known for its flower, which is the largest solitary flower on earth. There are plants with larger inflorescences as Amorphophallus titanum and parasol fan palm (Corypha umbracullifera), but these plants involves a cluster of flowers. Rafflesia arnoldii is found only in the rainforests of Borneo, Sumatra, the Philippines and Malaysia.
Different species Rafflesia grow in the jungles of Southeast Asia. Many species are endangered. Rafflesia arnoldii is the largest species. His flower reaches a diameter of nearly one meter and weighing up to 11 kg. Not only does this plant the largest flower on earth, it is also one of the most bizarre and misunderstood organisms in the world.
The plant lives as a parasite on the lianas of the genus Tetrastigma, which only grow in undisturbed primary forests. Most parasitic plants look similar to regular plants, but Rafflesia arnoldii has no observable leaves, roots or stems. Similar to fungi grows Rafflesia arnoldii with thread-like strands of fabric completely surrounded by and in close contact with host cells, of which water and nutrients are concerned. Perhaps the only area in which Rafflesia arnoldii if plant is to recognize the flower, although even these are weird because of the large size, reddish brown and the smell of rotting flesh. The flower is pollinated by carrion flies, which are attracted to. Because of its odor
Rafflesia arnoldii is rare and hard to find. Especially flowering plants are rarely behold. The flower bud does take months to develop, while the flower a few days remain good. How many of these plants are still unclear, as the primary forests of Borneo and Sumatra disappear rapidly.
Pollination is a rare event for various reasons. The flowers are unisexual and the plants in a particular place usually produce only male or female flowers. For effective pollination male flowers must be so in the vicinity of female flowers are. The flowers must also be open at the same time so that the flies can provide. Pollination
80-90% of the buds dies, so that even when male and female flowers in each other's vicinity, the chances of pollination decreases. Flower also keeps five to seven days well. The different populations are also separated from each other by the destruction of habitat. This depends on successful reproduction of the unlikely event off that a male and a female flower bloom simultaneously and that the pollinators move pollen between often distant populations.
Although Rafflesia arnoldii to the plant kingdom belongs, lacking a distinctive feature: it has no chlorophyll and therefore misses the opportunity to photosynthesis (like the whole family Rafflesiaceae).
Rafflesia arnoldii is one of the three national flowers of Indonesia, alongside the Arabian jasmine (Jasminusm sambac) and the moon orchid (Phalaenopsis amabilis).
In January 2007 it was announced that scientists at Harvard University have deduced that the early history of the genus Raffesia lies in the spurge family (Euphorbiaceae). Using molecular research This will lead to a discussion of these plants in the family have to be inserted.
