Fifteen noteworthy collections from Mississippi, U.S.A.

Abstract

Mississippi is an “under-botanized” state, with no state flora or atlas, a paucity of voucher specimens from many counties, and few county or local floristic inventories. 12 taxa are reported new to the flora of Mississippi or with only false, dubious, or unsubstantiated previous record; three significantly rare taxa with little previous record in the state are reported for new counties or ecoregions. Voucher specimens for each taxon are deposited at the Mississippi Museum of Natural Science (MMNS) or University of North Carolina, Chapel Hill (NCU) herbarium, and duplicates for some taxa at the University of West Alabama (UWAL), Austin Peay State University (APSC), University of Southern Mississippi (USMS), and Mississippi State University (MISSA) herbaria. I have excluded detailed locality information here, as all of the native taxa are significantly rare in the state and on unprotected land. The habitat, rarity, and distribution within the state of each taxon are discussed.
