During the Spring 2022 semester, students in Dr. Baghai-Riding’s Plant Anatomy course at Delta State University, were assigned a semester group project on a herbaceous weed found in the Mississippi Delta. Our group selected Geranium dissectum L. (cut-leaved cranesbill), an invasive species, that occurs throughout the eastern, southern, and western regions of the United States. This species inhabits waste grounds, grasslands, hedgebanks, and other disturbed areas. Cut-leafed cranesbills blooms from February – April in the Mississippi Delta grows 12” to 24” in height 1” to 1.5” in length. Single-edged razor blades were used to take anatomical sections of its leaves, roots, stems, and flowers. Digital photographs were taken with Q-Color 3 camera that was attached to an Olympus BX43 microscope. Longitudinal cuts of the stem possessed xylem cells showing secondary annular thickening. The upper epidermis of the leaves has trichome bases and regular epidermal cells that resemble jigsaw puzzle pieces. Leaf lower epidermal peels possess anomocytic stomata, since stomata complex lack subsidiary cells. Mesophyll containing chloroplasts occurred on leaf peridermal sections. Transverse root sections possess the xylem in the center and an abundance of starch grains in the cortex, which is common in dicotyledonous angiosperms. Trichomes were found on the leaves, leaf petioles, stems, and flowers. Pollen grains were present on the petals and anthers. The anatomical features evaluated are typical for other species of geranium. Future work will include measurements of cells and reproductive structures.
