FIRST DOCUMENTATION OF DICHANTHELIUM CAERULESCENS (POACEAE) FOR THE VASCULAR FLORA OF LOUISIANA, U.S.A.

Dichanthelium caerulescens is documented for the first time in Louisiana, as the result of floristic fieldwork performed in 2019 through 2021. Louisiana records extend the range of D. caerulescens westward by approximately 265 mi (426.5 km) into the Western Gulf Coastal Plain ecoregion. These findings also identify a new habitat, coastal prairie, utilized by D. caerulescens. [ABSTRACT FROM AUTHOR]
