Family Poaceae in Order Poales
What is a Family (pl. Families)?
In the context of botanical taxonomy, the Family rank is a taxonomic rank that is used to classify groups of related genera within an Order. Families are based on a set of shared morphological, anatomical, and genetic characteristics, such as flower structure, fruit type, and leaf morphology. The Family rank is situated between Order and Genus in the hierarchy of taxonomic ranks.
Each Family can include one or more genera, and each genus can include one or more species. Families are used to group genera of plants that share common traits and evolutionary histories, allowing botanists to better understand the relationships between different groups of plants.
