Ecology & Natural History
Habitat: Species is distributed in ravines and valleys. ILPIN Notes: (Carex amphibola Steud. var. turgida Fern. & C. amphibola var. rigida (Bailey) Fern. - R. 4); SCS-V.2 - less than Carex amphibola Steud. turgida Fernald; greater than Carex corrugata Fernald. The description of C. grisea includes the description of C. amphibola var. turgida, and plants of C. grisea have been included in the description of C. corrugata; one or more sources have used C. grisea to include plants covered by C. corrugata. Terminal spike is staminate or barely with a few perigynia. Lateral spikes 3-5, pistillate. Species is found throughout Illinois. This is a robust plant, 2-8 dm tall. Leaves are flat, dark green. Plant base brown-green. Staminate spikes are inconspicuous, sessile to short-peduncled. Pistillate spikes are clustered towards the culm tip, are thick and long, with many perigynia. Pistillate scales often exceed perigynia and have a long, scabrous awn. Perigynia are inflated. This species is similar to Carex amphibola but is more robust (Ref. 2). Functional Relationships:
