The status of Hordeum brachyantherum in eastern Canada, with related discussions
Hordeum brachyantherum Nevski (H. boreale Scrib. et Sm.) was thought, hitherto, to be disjunct with its main area in Alaska, the Rockies, and adjacent parts, and of relict nature in Newfoundland and Labrador. This study, using micromorphological characters from the lodicules and epiblasts has reveal...
