Brachyelytrum is a genus of North American and East Asian plants in the grass family, classified in its own tribe Brachyelytreae. Molecular phylogenetic study has indicated that Brachyelytrum is the earliest diverging lineage in the subfamily Pooideae (the cool season grasses), a lineage that includes many of the world's major cereal crops such as barley, wheat, and oats.
