Family Juglandaceae in Order Fagales

In botanical taxonomy, a family is a rank used to classify groups of related genera within an order. Families are defined by shared morphological, anatomical, and genetic characteristics (for example, features of flowers, fruits, seeds, or leaves). In the hierarchy, family sits below order and above genus.

Each family can include one or more genera, and each genus can include one or more species. Grouping genera into families helps botanists understand evolutionary relationships and organize plant diversity into natural, comparable units.
