Poaceae (Gramineae)
Abstract The grass family (Poaceae or Gramineae) is the fourth largest flowering plant family and contains approximately 11 000 species in nearly 800 genera worldwide. We currently recognise 12 subfamilies: Anomochlooideae, Pharoideae, Puelioideae, Bambusoideae, Ehrhartoideae, Pooideae, Aristidoidea...

A grass is characterised by having a one‐seeded fruit known as a caryopsis or grain. The primary inflorescence is referred to as a spikelet with 1–many, two‐ranked bracts inserted along the floral axis or rachilla. The grass family is classified into 12 subfamilies, 50 tribes and 81 subtribes. A highly reduced floral structure and wind pollination has enabled the family to be extremely successful at planet‐wide radiation and colonisation.
