Convolvulaceae

Some plants like to wind and climb.

These are called morning glories. Their stems often curl around things.

Their flowers look like little funnels. Many of these plants are vines. Some can even grow into trees. Some are small bushes.

You can eat some of them. The sweet potato is a famous one. People also eat water spinach.

Some plants in this group are weeds. They can be hard to stop. Other plants in this group are very pretty in gardens.

It is fun to see them grow!

The Convolvulaceae family is a big group of plants.

Many people call them morning glories or bindweeds. This family has over 1,650 different species. Most of them are vines that wind around things.

Some are small herbs or bushes. A few can even grow into trees.

You can find many useful plants here. The sweet potato is a very famous one. People also eat water spinach.

Some plants are used as medicine. Some flowers are very pretty in gardens. Other plants, like dodder, are parasites. A parasite is a plant that lives on another plant.

These plants have special flowers. The petals are fused together. This makes the flower look like a funnel. The flowers have five parts. They also have five sepals, which are small leaf-like parts at the base. Some plants in this group have special chemicals. These chemicals come from a link with fungi. This is called symbiosis. Symbiosis is when two living things live closely together to help each other.

The Convolvulaceae family is a large group of flowering plants.

People often call them morning glories or bindweeds. This family contains more than 1,650 different species. Most of these plants are herbaceous vines.

However, the family also includes shrubs and small herbs. Some species can even grow into medium-sized trees. These plants matter because they provide food and beauty to the world.

Many of these plants have a very specific way they grow. Their stems are usually winding or twisting. This is why their Latin name comes from the word *convolvere*, which means "to wind."

Their flowers have a unique shape called a corolla. This corolla is funnel-shaped and looks the same from all sides. The flowers have five fused petals and five sepals at the base. Inside, they have five stamens that are attached to the petals. The fruit can be a berry, a nut, or a capsule.

Scientists have studied how some of these plants work with fungi. Some species contain special chemicals called ergoline alkaloids.

These chemicals likely come from a special partnership called symbiosis. In this relationship, a fungus lives on the plant. A recent study looked at the plant *Ipomoea asarifolia*. Researchers used DNA sequencing to find a specific fungus on it. This fungus belongs to the family Clavicipitaceae. It is passed from one generation to the next through seeds.

There are many important names and numbers in this plant family. The family includes about 60 different genera. One famous member is the sweet potato, which is a type of edible tuber. Another useful plant is water spinach, which people use for food. Some members, like the genus *Cuscuta*, are known as dodder. Dodder is a parasite that lives on other plants. In these parasitic plants, the leaves are reduced to tiny scales.

You might recognize these plants in your own life. You may see morning glories growing in a garden.

You might also see bindweed as a troublesome weed in a yard. Some people even use certain species for medicine. While some are helpful, others like dodder can be quite tricky. Whether they are food, flowers, or weeds, these plants are all part of one big family.

The Convolvulaceae family is a vast and diverse group of flowering plants.

It includes about 60 different genera and more than 1,650 distinct species. Most members of this family are herbaceous vines, which are soft-stemmed plants that climb. However, the family is not limited to vines. It also contains shrubs, small herbs, and even medium-sized trees like *Humbertia madagascariensis*.

These plants are important to humans for many reasons. They provide colorful flowers for gardens, food for people, and even medicinal ingredients.

You can identify a member of the Convolvulaceae family by looking closely at its flowers. The flowers feature a funnel-shaped corolla, which is the part made of petals. This corolla is radially symmetrical, meaning it looks the same from all sides. The floral structure follows a specific pattern. It has five sepals at the base and five petals that are fused together. Inside the flower, there are five epipetalous stamens. This means the stamens, the male parts, are physically attached to the petals. The female part, called the gynoecium, is a two-part syncarpous and superior structure.

The growth habit of these plants is also very distinctive. The stems are usually winding or twisting as they grow. This characteristic is why the family has the Latin name Convolvulaceae. The name comes from the word *convolvere*, which means "to wind."

Most species have simple, alternate leaves that do not have stipules. However, some members have changed how they grow. In the parasitic genus *Cuscuta*, also known as dodder, the leaves are reduced to tiny scales. This happens because the plant relies on other hosts for survival.

Some members of this family have fascinating chemical properties. Certain species contain ergoline alkaloids. These are special chemical compounds that can have strong effects on the body. Scientists believe these chemicals are not made by the plant alone. Instead, they likely come from a symbiosis, which is a close partnership between two different organisms. In this case, the plant lives with a fungus from the family Clavicipitaceae.

A recent study of the plant *Ipomoea asarifolia* confirmed this relationship. Researchers used DNA sequencing of 18s and ITS ribosomal DNA to identify the fungus. They found the fungus is an obligate biotroph, meaning it must live on its host. It is also seed-transmitted, passing from parent to offspring through the seeds.

Another group of chemicals called loline alkaloids has been found in some species. These are often produced by fungi in the genus *Neotyphodium*. While researchers know these alkaloids exist in some convolvulaceous plants, the exact origin in those specific species is still unknown. These chemical studies help us understand the complex ways plants and fungi interact in nature. This relationship shows how a single plant can be part of a much larger biological system.

Humans use many species in the Convolvulaceae family for daily needs. The sweet potato is perhaps the most famous example. It is an edible tuber, which is a thickened underground part of a stem. Water spinach is another common food plant. Beyond food, some species are used for their medicinal value. For instance, some seeds are used as purgatives, which are substances that help clear the bowels. However, some species must be handled with care because of their potent alkaloid content.

In many environments, these plants are known by different names depending on how they are used. In a beautiful garden, you might see the showy flowers of a morning glory.

In a field or a yard, you might encounter bindweed, which is often considered a troublesome weed. Genera like *Convolvulus* and *Calystegia* are common examples of these weeds. Whether they are being grown for food, decoration, or managed as weeds, the Convolvulaceae family remains a vital part of the Earth's botanical landscape.
