Slender Woodland Sedge


CAYUGA FLORA (1926) NOTES: Wooded slopes, in humus on clay-gravel or stony neutral soils ; locally common. June. Woods near Michigan Hollow Swamp; Inlet Valley, s. of mouth of Enfield Glen; Six Mile Creek; Cascadilla woods; Fall Creek Gorge; Cornell Heights; Renwick slope; Esty Glen; glen one mile s. of Willets; Howland Island; and elsewhere. Me. to Minn., southw. to Fla. and Tex.; rare or absent on the Coastal Plain. This species differs from C. laxiculmis in the narrower green leaves, in the smaller perigynia (2.5-2.8 mm long instead of 3-4 mm long), and in the absence of the one or two sterile flowers at the base of the pistillate spikes. The upper bracts usually exceed the staminate spikes. Intermediate forms between these species are occasional (var. copulata Bailey), combining various characters of the two plants. They strongly suggest a hybrid origin.
