Morphological And Ecological Investigations Of Species Of Bulrush (Scirpus) In Illinois, Julian G. Moore
Masters Theses
Two closely related species of bulrush, Scirpus atrovirens (Green bulrush) and Scirpus georgianus (Georgia bulrush), are widely distributed in Illinois. They are difficult to separate in the field, but readily distinguishable under magnification in the lab. These two species have been found in moist meadows, shallow marshes, edges of wet forests, and ditches. The objective of this study was to evaluate the morphological and ecological distinctness of the species with the aim toward discovering and describing other features to distinguish them reliably. Eighty plants of Scirpus atrovirens and 80 of Scirpus georgianus were examined. Fifty S. atrovirens and 50 S. …
