CEGL003332 Carex cusickii - (Menyanthes trifoliata) Fen
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Cusick''s Sedge - (Buckbean) Fen
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This wetland association is known from the Puget Lowlands of Washington, Georgia Basin of British Columbia, and the Coast Ranges of northwestern Oregon. It usually occurs as floating mats or narrow margins around lakes or ponds, some of which are associated with bogs. The mats are composed of fibrous or sphagnum peat which is saturated. Carex cusickii consistently dominates this herbaceous vegetation. Comarum palustre is usually present and occasionally codominant. Other common species include Menyanthes trifoliata, Hypericum anagalloides, and Sphagnum spp., the latter occasionally covering most of the substrate. This association is distinguished by the dominance of Carex cusickii and the presence of Menyanthes trifoliata or Sphagnum spp.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The current treatment here combines Kunze''s (1994) two coastal Carex cusickii types (with and without Sphagnum) into the entity described herein, and recognizes a separate Carex aquatilis var. dives / Sphagnum spp. based on Kunze (1994) and Murray (2000). East of the Cascades has a different type, ~Carex cusickii Fen (CEGL000230)$$, that is more often found in fens.
