What is difference between poaceae and gramineae family?

The Poaceae and Gramineae families refer to the same group of plants, commonly known as grasses. "Poaceae" is the modern scientific name adopted by botanists based on updated classification systems, while "Gramineae" is an older term that is still occasionally used. Both names encompass a diverse group of flowering plants that are crucial for ecosystems, agriculture, and human consumption. Thus, there is no difference in the group itself, only in the terminology used to describe it.
