Name: Iva annua - (Xanthium strumarium) Ruderal Wet Meadow
Reference: NatureServe Biotics 2019
Description: Stands of this vegetation occupy temporarily/seasonally flooded areas occupied by significant stands (usually monodominant or heavily dominated) of the weedy forb <i>Iva annua</i>. These are successional, temporarily flooded habitats such as riverine depositional zones or post-cultivation (old field) areas. Stands of this vegetation may be dense or more patchy and open. This vegetation is known from Oklahoma and probably Texas, and may be found in adjacent Kansas, Missouri, or Arkansas. It is not reported from east of the Mississippi River, but the nominal species is known from most of the eastern United States. Some stands may be too small and short-lived to qualify as examples of this vegetation type. The extinct taxon <i>Iva annua var. macrocarpa</i> was known from Arkansas, Missouri, and Tennessee, where it apparently served as a Native American food plant.
