Extreme Plant Design – Rafflesia

 Extreme Plant Design - Rafflesia

The world’s largest and most awful-smelling flowers grow in the rain forests of the Philippines, Malaysia, Indonesia, and Thailand. They are produced by about 28 species of plants in the genus Rafflesia. These examples of extreme plant design have the odor and even the appearance of rotting flesh. 

Rafflesia are parasitic plants that grow under the bark of woody vines in the genus Tetrastigma. The vines of Tetrastigma are also parasitic plants that use host trees to reach sunlight for photosynthesis. So you could say that makes Rafflesia plants parasites of parasites. Rafflesia plants grow inside the Tetrastigma vines so that their only visible part is the flower. They have no roots or stems.

The Rafflesia flowers have five petals and can be 40 inches (100 cm) or more in diameter and weigh 22 pounds (10 kg) or more. Because of the odor of these flowers, they attract flies and insects that feed on dead animals. Those insects transfer pollen from the male flowers to the female flowers, which the males outnumber. 

But that isn’t the end of this extreme plant design story. Tetrastigma vines have a defense mechanism to prevent the Rafflesia from growing and taking energy from them. They produce chemicals called benzylisoquinoline alkaloids that are related to morphine and codeine. Those chemicals sometimes prevent the Rafflesia from growing in the Tetrastigma vine. However, it doesn’t work all the time. Jeanmaire Molina, a plant biologist at Long Island University, is trying to find out why. She thinks that Rafflesia may have a way to suppress the Tetrastigma’s alkaloid production. 

Scientific American magazine quoted Harvard biologist Charles Davis commenting that this research into extreme plant design is essential to understanding the interaction between parasites and hosts. He said that “plants are incredible chemists.” We agree that plants are incredible chemists, but only because the Master Chemist has fine-tuned plants and all of life to survive and thrive on this incredibly well-designed planet. God has given us plants to provide oxygen, food, and a wide range of medical products that enrich our lives. 

In a previous post (December 4, 2021), we reported on the titan arum (Amorphophallus titanum), which is known as the “corpse flower.” It also produces the smell of a rotting corpse and attracts flies for pollination. Interestingly, the titan arum uses the same means for pollination, but it is not related to Rafflesia. Evolutionists would call that “convergent evolution,” but we call it evidence of a common Designer.

Corpse Plant Design and Pollination

The design of plants is so complex and precise that it speaks volumes about the design built into all of life. For example, on November 3, 2021, the San Diego Botanic Gardens in Encinitas had a public showing of the bloom of the Amorphophallus titanum plant, which attracted more than 5,000 people. This strange plant is called the corpse plant.

Amorphophallus titanum is an endangered plant endemic to Sumatra. People call it the corpse plant because the blossom smells like a rotting corpse. The plant requires growth for five to ten years before blooming for the first time. After that, it may bloom once every two to ten years. The bloom lasts for 24 to 48 hours in which it sends out the odor to attract carrion beetles and flesh flies as pollinators.

The flower, or spathe, of the corpse plant does more than just send out a smell to attract pollinators. The inside is a deep red color with furrows that give it the appearance of raw meat. Also, when blooming, it generates heat that brings it to human body temperature. As a result, the carrion beetles and flesh flies, which are programmed to be attracted to meat, find it irresistible.

Many insects and animals have a symbiotic relationship with certain plants. Sometimes a plant attracts an insect or animal for food or shelter, and the insect or animal provides pollination for the plant. Analysis of the powerful odor shows it involves at least seven chemicals that create foul smells we are familiar with, from rotting fish to feces. It is no accident that this plant has all of the right chemicals and physical features to attract the available pollinators in its native habitat.

The needs of every plant and animal are carefully provided for their survival. The evidence is apparent as Romans 1:20 tells us we can know there is a God through the things He has made. The corpse plant, carrion beetles, and flesh flies demonstrate the truth of that statement.
