"Brachyelytrum japonicum ""Brachyelytrum" is a small
grass genus that occurs in easternNorth America and easternAsia . It is one of several grass species that displays this classic floristic disjunction pattern. There are three species recognized currently in "Brachyelytrum": "B. aristosum" (distributed in southeastern Canada and the northeastern USA), "B. erectum" (distributed in the northeastern USA and adjacent southern Canada), and "B. japonicum" (distributed in Japan and southeastern China).Recent molecular phylogenetic study has indicated that, within the grass family (
Poaceae ) "Brachyleytrum" is the sister-group of the subfamilyPooideae (the cool season grasses), a lineage that includes many of the world's major cereal crops such as barley, wheat, and oats.
