CEGL004124 Iva annua - (Xanthium strumarium) Ruderal Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Annual Marsh-elder - (Rough Cocklebur) Ruderal Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: Stands of this vegetation occupy temporarily/seasonally flooded areas occupied by significant stands (usually monodominant or heavily dominated) of the weedy forb Iva annua. 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 Iva annua var. macrocarpa was known from Arkansas, Missouri, and Tennessee, where it apparently served as a Native American food plant.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Some stands of the nominal species may be too small and short-lived to qualify as examples of this vegetation type. The original (2006) hydrologic assignment is approximate, but these are wetlands not uplands. The formation placement should be subjected to further review as more data become available. It could be either temporarily or seasonally flooded.

Physiognomy and Structure: No Data Available
Floristics: This type is represented by significant stands (usually monodominant or heavily dominated) of the weedy forb Iva annua. Stands may be dense or more patchy and open. Some disturbance-oriented annual forbs may be present, in particular Xanthium strumarium, along with seedlings of some woody plants (e.g., Platanus occidentalis, Salix nigra). In Oklahoma, associated species include Ambrosia trifida, Bothriochloa saccharoides, Cnidoscolus texanus, Lespedeza cuneata (= Lespedeza sericea), Passiflora incarnata, and Sorghum halepense (Hoagland 2000).
