Interpretive Summary: The flora of the Yazoo-Mississippi Delta region is poorly known compared to the rest of Mississippi or adjoining states. Fifteen species are reported new to the Yazoo-Mississippi Delta Region and significant range extensions are provided for five additional species. Of these, four are invasive weeds, including water hyacinth a federal noxious weed. Three species are on the special concern list of rare plants in Mississippi.

Technical Abstract: The flora of the Yazoo-Mississippi Delta region is the least represented in the checklist of Mississippi plants currently being compiled for the state. This paper reports 20 noteworthy collections from the region and discusses their distributions within the state. Typha angustifolia is reported new to Mississippi and Bowlesia incana, Caperonia palustris, Carya cordiformis, Carya glabra, Chenopodium standleyanum, Eichhornia crassipes, Hottonia inflata, Oplismenus setarius, Podophyllum peltatum, Polystichum acrostichoides, Proserpinaca palustris, Scirpus atrovirens, Senecio vulgaris, Sparganium americanum, and Spigelia marilandica are reported new to the Yazoo-Mississippi Delta Region. Range extensions are reported for Callicarpa americana, Carex intumescens, Carya laciniosa, and Menispermum canadense within the Yazoo-Mississippi Delta Region. Of the 20 species, Bowlesia incana, Caperonia palustris, Eichhornia crassipes, and Senecio vulgaris are weeds. Carya laciniosa, Hottonia inflata, and Mensipermum canadense are plants of special concern within the state and are on the state’s special plant tracking list.
