For a number of years the writer has been engaged in a taxonomic and distributional study of the grasses of North Carolina. During this study about 345 species and varieties have been recorded for the state. Since the publication of the Manual of Grasses of the United States,1 continued collecting and search for additional specimens in various herbaria, have added several species not reported from the state and extended the local ranges of many others. While some of the grasses new to the state are undoubtedly transients of recent introduction, the majority are native or naturalized annuals and perennials. Of the latter some were to be expected in the state because North Carolina was included in their respective ranges, while the new records of others represent more or less marked extensions of range.
