Spisies: R. Arnoldii
Rafflesia is a lot of people are known arnoldii Rafflesia species. This type of forest only grows in the southern part of Sumatra, especially Bengkulu. One of the most excellent and easy to find this arnoldii Rafflesia flowers are in the woods along the road-Curup Bengkulu after Kepahyang. In Bengkulu own, Rafflesia flowers have been used as the main motive besurek batik (batik typical Bengkulu) since long.
The main characteristic that distinguishes the bungabangkai Rafflesia, the laity is a broad-form (not high) and red. When blooming, the flowers can reach a diameter of about 1 meter high and 50 cm. Rafflesia flower has no roots, stems, or leaves. The flowers have 5 crowns. At the bottom of the barrel-shaped flowers have flower or pistil extracts, depending on the sex of flowers. the existence of the pistil and stamens are not in one house to the percentage of assisted fertilization by insects fly very low, because not two different flowers growing in sex at the same time the nearby places. This rate of growth period takes up to 9 months, but the flowering period is only 5-7 days. After that Rafflesia will wither and die.
Rafflesia is a parasitic plant on vines Obligate (liana) tetrasigma and live in the roots like a rope. Until now Rafflesia never bred successfully outside their natural habitat and if the root or its host tree dies, Raflesia will die. Raflesia therefore require primary forest habitat to survive.
Little information, during the year 200an plants of the genus Rafflesiaceae difficult to be classified as characteristics of the body that are not public. Based on the DNA research by botanical experts at Harvard University recently, Rafflesia incorporated into the family Euphorbiaceae, a family with rubber trees and cassava. But this is still not well published.
Spisies: A. titanum
Rafflesia addition, another giant flower known to the public is a dead flower / suweg giant. The most popular among other types of carrion flower is a type of titanium amorphpophallus. This type of endemic species only grows in the forest area in Sumatra. In fact, there is also a mention of this flower as the official flower of Bengkulu province.
In contrast to the Rafflesia, titan arum corpse flower is creamy on the outside and on the rising. While red crown to the purple. Brief current form looks like a flower blooming trumpet. If the Rafflesia is only widening, flowers grow towering dead. Carrion flower height Amorphophallus titanium species can reach about 4 m with a diameter of about 1.5 m.
Titan arum is the plant of the tribe, including taro-talasan (Araceae). Is a plant with compound interest in the world’s largest. Unlike the Rafflesia can not grow in other areas, carrion flower cultivation can be. when the parasitic Rafflesia in vines and flowers growing on a dead bulb itself.
These flowers have 2 phases in life that appear alternately and continuously, ie vegetative and generative phase. In the vegetative phase, in the tubers will emerge a single stem and leaves similar to glimpse papaya trees. High tree can reach 6m. After a few years, generative organs will shrink unless the tuber. If the environment supports, and the tuber is eligible trees will be replaced with a dead flower growing. The growth of compound interest which replaced the withered tree is the generative phase of this plant.
According to the location attendant carrion flower cultivation in the forest Kepahyang, Bengkulu, new flowers can grow when the tuber has a minimum weight of 4 kg. When the food reserves in the tubers less or have not weighed 4 pounds, then the tree will wither replaced by new trees.
In addition, carcass flower is to plant one and protogini house, where the female flowers receptive first, then followed by male flowers cooking, as a mechanism to prevent self pollination. Stench issued by this interest, such as the Rafflesia, serves to attract beetles and flies pollinators for flowers. After the flowering period (approximately 7 days) passed, dead flowers will wilt. And going back through the cycle, return to the vegetative phase, where new trees will grow over the dead flower bulbs used.
When flowering occurs during fertilization, the fruit will form red-colored fruit with seeds on the former base of the flower. These seeds can be planted a tree in the vegetative phase.
