Many plants are in one big group.
Many plants belong to one big group.
Many different plants belong to one big group. This group is called Caryophyllales. It has 38 families and over 11,000 species. 


The Caryophyllales is a very large and diverse group of flowering plants. This group includes many different types of plants that we see often. You might recognize garden carnations or even foods like beets and spinach. Some members are succulents, which means they have thick, fleshy stems or leaves. Other plants in this group are even more unusual because they are carnivorous. This means they eat insects to survive. This group is important because it contains about 6% of all eudicot species.
These plants have special ways of working that make them unique. Many families in this group use betalain pigments to create their colors. These pigments are a special way for plants to show color. However, not all members use them. Some families, like Caryophyllaceae, do not use betalain at all. Other groups, like the Nepenthaceae, use different pigments called anthocyanins instead. This variety in how they make color is a big part of what makes the group interesting. 
Scientists have spent a long time studying how to group these plants. In 1936, researchers like Douglas and Dickson looked at how flowers were built. They studied the vascular patterns and how ovaries were shaped. Earlier systems, like the Wettstein system from 1935, used different names. Some old systems called this group Centrospermae. Today, scientists use DNA sequences to help them understand these relationships. This helps them prove that these plants belong together in one single group. 
There are many specific numbers that describe this large group. Currently, the Caryophyllales contains 38 families and 749 genera. There are also 11,620 different species within the group. Scientists believe this lineage split from other plants about 111 million years ago. The way we group them has changed through many updates. For example, the APG IV system from 2016 is the most recent way to classify them. This system added several families over time to make the group more complete. 
You can find these plants in many parts of your daily life. Some are used for food, like quinoa or buckwheat. Others are found in gardens, like bougainvilleas or four o'clock flowers. You might even see cacti in a desert or a shop. Even plants like the Venus flytrap belong to this big family. Whether they are growing in a field or in a pot, they are part of this amazing group.
The Caryophyllales is a large and diverse order of flowering plants. This group is part of the core eudicots, which is a major group of flowering plants. Within this order, you can find many different types of life. Some members are famous garden flowers like carnations. Others are important food crops like beets, spinach, and quinoa. You might even see succulents, which are plants with fleshy stems or leaves, like cacti. This order is quite significant because it contains about 6% of all eudicot species.
One of the most interesting things about these plants is how they create color. Most core families in the Caryophyllales use special pigments called betalains. These pigments give the plants their distinct colors. However, this is not true for every single member of the order. The families Caryophyllaceae and Molluginaceae do not use betalains at all. Some other families, known as noncore families, use a different pigment called anthocyanins instead. This includes groups like the Nepenthaceae. 
Scientists have discovered that this group is very large. Currently, the Caryophyllales includes 38 different families. Within those families, there are 749 genera and 11,620 distinct species. The history of this group goes back a very long time. Molecular clock calculations suggest the lineage split from other plants about 111 million years ago. To prove these plants belong together, scientists look at DNA sequences. They also look at heritable characters. These include how the anther walls develop and the structure of vessel-elements with simple perforations. 
The way we classify these plants has changed over many years. In the past, different systems used different names. The Wettstein system from 1935 and the Engler system from 1964 both used the name Centrospermae. Earlier researchers also studied the anatomy of the flowers to find connections. For example, in 1936, researchers like Douglas and Dickson studied vascular patterns. They looked at how the ovaries were shaped and how the locules were placed. This helped them understand how modern flowers might have descended from older ancestors. 
Today, many scientists use the Angiosperm Phylogeny Group, or APG, system. This system has been updated several times to include more families. The original APG system in 1998 included 26 families. Since then, more families have been added during different revisions. The APG II system in 2003 added three families. The APG III system in 2009 added five more families. Finally, the APG IV system in 2016 added four more families. This makes the order much larger than it was in the older Cronquist system from 1981. 
The order is often divided into two main suborders. These are called Caryophyllineae and Polygonineae. In some older classification systems, these two groups were actually treated as two separate orders. One was called Polygonales and the other was Caryophyllales. Modern definitions have expanded the group to include many families that were once part of Polygonales. This expansion includes several families of carnivorous plants. These plants, such as the Droseraceae, have unique ways of getting nutrients.
You can find members of the Caryophyllales in many different environments. Some grow in dry places, like the Cactaceae family. These plants, such as the Gymnocalycium Matoensea, are often native to regions like South America.
