Fibrous-root Sedge (Carex communis)

Also known simply as Fibrous Root Sedge, Carex communis is a perennial sedge recognized for its characteristic fibrous root system.

Considerations for Pets

• This plant has fibrous roots.
• The text mentions that other sedges have tubers and rhizomes.
• The leaves are described as scabrous distally, meaning they might be rough or slightly abrasive to the touch.

Taxonomy and Nomenclature

• Scientific Name: Carex communis L.H. Bailey
• Common Name: Fibrous-root Sedge
• Family: Cyperaceae (Sedge family)
• Kingdom: Plantae
• Synonyms: Carex communis var. communis

Morphology and Growth Habits

• Carex communis is a perennial, grass-like plant, often forming tussocks (clumps).
• Culms (stems) are typically 20-60 cm tall and scabrous (rough) towards the distal end.
• Flowering stems are described as smooth and sharply 3-angled, with a purplish base.
• Flowers are dry and tiny, with a male spike located at the top of the stem.
• It possesses a fibrous root system and may spread via underground rhizomes and/or aboveground stolons.
• The root system can be extensive and complex.

Distribution and Habitat

• The plant is terrestrial and found in New England states such as Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont.
• It can be found in habitats ranging from sedge meadows to calcareous fens, wet prairies, and bogs.

Ecological Role

• The fibrous root systems of sedges are effective at preventing soil erosion and promoting slope stability.
• Sedge meadows, dominated by sedges, are often found on saturated soils.

Interactions with Other Organisms

• The text mentions that in pastures, Navua sedge (Cyperus aromaticus) is unpalatable and provides little feed value for cattle.
