Description
C. rigidula is a perennial gaminoid of the Poaceae family that is native to North America. [2] C. rigidula ssp. condensa is easily identified by its compact inflorescence and tall stature. This subspecies can also resemble C. anceps ssp rhizomata, and can be differentiated by having sheaths that are glabrous to appressed pubescent distally.[1]
Distribution
C. rigidula can be found across the eastern side of North America and along the western coast of the United States and Canada. [2] C. rigidula ssp. condensa can be found in the Coastal Plain from southeast Massachusetts south to Florida and west to southeast Texas as well as disjunct in the West Indies, while C. rigidula ssp. rigidula can be found across the rest of its native range.[1]
Ecology
Habitat
Common areas C. rigidula can be found include marshes, meadows, peaty or wet sandy soils in low woods, shores of streams and ponds, swamps, ditches, and it can often be quite weedy.[1] Ideal habitat for C. rigidula is in moist regions, for instance, wooded floodplains, marshes, moist loamy sand at edge of woods, moist depressions, lower tidal hammock, swamp forests, pine flatwoods, edge of rivers, bottomland of wooded areas, and shores of lakes.
