Ecology & Natural History
Habitat: Species is found in shade with Ulmus americana, see also SAF Forest Cover Type, wet river bottom prairies, swampy meadows, alluvium in wet, open valleys, sloughs, ditches, along railroads, and in rich wooded valleys. ILPIN Notes: Perigynia wing-margined, lower part firm, without spongy thickening; plants mostly cespitose, sans well-developed rhizomes. Mature perigynia ovoid to suborbicular, less than or equal to 2 1/2 times longer than wide; spikes globose, mature perigynia beaks spreading -recurved; wing abruptly narrowed below middle, thus, base wingless - sterile culms with spreading non-clustered leaves - common. Field ID - crowded, nearly globose spikes with perigynia wide-spreading; and by numerous spreading leaves on the numerous sterile culms. Most spikes have pistillate flowers at the apex. Some authors consider this as originating from a hybrid between C. tribuloides and C. Bebbii. Functional Relationships:
