Rosidae facts for kids
Rosidae is a special name used in the world of plants. It's like a big group, or "subclass," that helps scientists organize different types of plants. Think of it as a large family tree for plants!
The main rule for a plant to be in the Rosidae group is that it must be related to the Rosaceae family. This family includes many plants you might know, like roses, apples, and strawberries.
What is Rosidae?
Rosidae is a way to classify plants, especially in an older system called the Cronquist system, which was used in 1981. This system helps scientists understand how different plants are related to each other. It groups plants based on their features, like their flowers, leaves, and how they grow.
How Plants are Grouped
In the Cronquist system, Rosidae was a very large group. It included many smaller groups called "orders." Each order then contained different plant families. Here are some of the orders that were part of Rosidae:
- Rosales (includes roses and their relatives)
- Fabales (includes peas, beans, and other legumes)
- Proteales (includes plants like proteas)
- Myrtales (includes plants like eucalyptus and myrtle)
- Rhizophorales (includes mangrove trees)
- Cornales (includes dogwood trees)
- Santalales (includes sandalwood trees)
- Rafflesiales (includes the giant rafflesia flower)
- Celastrales (includes bittersweet vines)
- Euphorbiales (includes spurge plants)
- Rhamnales (includes buckthorn plants)
- Linales (includes flax plants)
- Polygalales (includes milkwort plants)
- Sapindales (includes maples and citrus trees)
- Geraniales (includes geraniums)
- Apiales (includes carrots and parsley)
Modern Plant Classification
Today, scientists often use a newer system called the APG III system. Even though the names and groups have changed a bit, many of the plants that were once in Rosidae are still grouped together. For example, the APG III system includes groups like:
- Crossosomatales
- Geraniales
- Myrtales
- Fabidae (a large group that includes many plants from the old Rosidae, like those in Celastrales, Cucurbitales, Fabales, Fagales, Huaceae, Oxalidales, Malpighiales, Rosales, and Zygophyllales)
- Malvidae (another big group with plants from Brassicales, Huerteales, Malvales, and Sapindales)
These new systems help scientists keep up with new discoveries about how plants are related, often using DNA information.
