Yesterday, we looked at the amazing design and structure of Victoria amazonica waterlilies. Named after Queen Victoria of England and the Amazon River where they grow, the huge leaves of these plants are amazing, and their flowers are beautiful. However, I think the most impressive is the reproductive system of Victoria waterlilies.

We have to call this a system because it involves a particular beetle species and several steps. The flowers of this plant last about 48 hours, changing from white to pink and from female to male.

On the first day, all the flowers of a single patch open at the same time. They are white female flowers that present a sweet, fruity fragrance that attracts scarab beetles of the genus Cyclocephala. When darkness falls, the flowers stop producing the scent and close, trapping the beetles inside. The beetles transfer pollen picked up from a previously visited flower.

On the second day, the flowers receive anthocyanins turning them pink to show that they have been pollinated. As the flowers remain closed, the beetles are treated to a starchy and spongy treat that nourishes them. The flowers then open to release the beetles, and the stamens of the now male flower deposit pollen on the beetle. The flower then closes and descends below the water while the beetle carries the pollen to a white flower in another location, where the process repeats.

This reproductive system of Victoria waterlilies cross-pollinates the plants while preventing self-pollination, as the flowers are female one day and male the next. The beetles are treated to nourishment as they carry out the pollination. The system depends on a plant species and a beetle species working together according to a timed sequence. Could this have happened by an accident of evolution, or does it show design? We think design is the best explanation, and design demands a Designer.

If you were going to build a barrier between the atmosphere and the water in a pond or lake, what material would you use, and how would you construct it? The construction industry would probably use concrete or iron. The problem with these materials is that they are vulnerable to chemical degradation and changes in temperature. In recent years, we have seen bridges collapse after relatively short periods of existence. Bridge design is difficult because the atmosphere presents a different set of problems than those encountered in the underwater world. God has an answer to this issue, which we can see in looking at the design and structure of Victoria waterlilies.

In the Amazon River, the leaves of the Victoria amazonica waterlily can grow to 10 feet in diameter. These lilies have very large, flat green leaves that grow on the surface of the water. The submerged stalk can grow to 26 feet long at an inch per hour. For protection from underwater herbivores, the salk and leaf bottoms are covered with numerous small spines.

The very large leaves have a network of veins underneath that some have compared to “transverse girders and supports.” This lattice-like structure under the leaves allows the plant to hold air, giving the leaf great strength and buoyancy. If the weight is evenly distributed across one leaf, it can support hundreds of pounds.

Many times, people have copied the amazing designs we see in the natural world, and Victoria water lilies may be one example. You can see them in many botanical gardens in the United States and other countries. Everywhere we look, we see the wisdom and design of God in His creation. However, the most amazing thing about the Victoria amazonica waterlily is the system it uses to reproduce. We will look at that tomorrow.
