Kasviheimo, also known as a plant family in English, is a fundamental taxonomic rank in botany, used to classify plants based on shared evolutionary relationships and morphological characteristics. It is a step below the order and above the genus in the hierarchical classification system. Plant families are named using the suffix "-aceae" for dicotyledons (angiosperms with two seed leaves) and "-aceae" or "-ales" for monocotyledons (angiosperms with one seed leaf). For example, the rose family is Rosaceae, and the grass family is Poaceae.

The concept of a plant family is based on the idea that plants within the same family share a common ancestor and have evolved similar traits over time. These traits can include leaf shape, flower structure, and reproductive characteristics. However, it is important to note that while plants in the same family may share certain similarities, they are not necessarily closely related to each other. The diversity within a family can be quite large, and some families may contain only a few species, while others may contain thousands.

Plant families are used in various fields, including botany, ecology, and conservation biology. They provide a useful framework for understanding the diversity of life on Earth and the relationships between different plant species. Additionally, they are important for identifying and classifying plants, as well as for studying their evolutionary history and adaptations to different environments.
