Amorphophallus Titanum or Titan Arumis one of the tallest flower in the world. It's also known as "corpse flower" or "bunga bangkai". It is because the smell of this flower is almost similar with the smell of decomposing animals. Some Indonesian people have mistaken "bunga bangkai" with raflesia arnoldii and they don't know that the real "bunga bangkai" is different with raflesia arnoldii. This flower is endemic to Sumatran rainforest. But, it has been cultivated around the world.
There is an orchid that represent the face of a monkey. This kind of orchid could be found in Ecuador. (I hope someone who'd be able to give me more information about what species this orchid belongs to be. It's so hard for me to research about it because there are other monkey orchids that I'm not sure that it's the same species with this one. But I think I should share about it here.)
The flowers of venus flaytrap, one of carnivorous plant, is attractive for bugs. It catches animals like arachnids and insects for food. But, some growers remove the flowering stem early (2–3 inches), as flowering consumes some of the plant's energy, and reduces the rate of trap production. If healthy plants are allowed to flower, successful pollination will result in the production of dozens of small, shiny black seeds.
Many flowers which grow in rainforests have many unique ways for pollination. The diversity of pollination's method is related with the high variety of species which live in rainforest. But, most of the rainforest flowers are pollinated by bees. Flowers that are pollinated by other types of insects have a different set of adaptations. Some flowers which are pollinated in the night (by bats' help) have pale colours. But, flowers which rely on bugs or insects for pollinating have bright colours.
Most of types of orchids grow in rainforest. There are about 25,000 species of them world-wide in 880 genera They make up the largest family of flowering plant and comprise nearly a seventh of all plant species. Some orchids are extremely rare and hard for gardeners grow.
The flower with the largest bloom in the world, Raflesia arnoldii, grows in Indonesian rainforest. It's also one of the rarest and endangered plants in the world. It is especially difficult to locate the flower in forests as the buds take many months to develop and the flower lasts for just a few days. The flowers are unisexual and thus proximity of male and female flowers is vital for successful pollination. These factors make successful pollination a rare event. The destruction in Sumatran's rainforest have led to their declining number. This species is near extinction.
