Definition: In botany, the term "subfossorial" refers to a group of plants that are related in some way and have similar characteristics. These plants may be closely related genetically or phylogenetically, but they do not form a separate species. They often belong to the same family or genus and share common traits such as having large leaves and flowers with small seeds. Subfossorial plants are found in moist areas of their environment where water is abundant, and their growth rates are slow.
