The inflorescences are longer than the proximal bracts. the distinct spikes are erect, oblong, and of similar length to each other. The pistillate scales are dark brown and lanceolate. The perigynia is ascending, pale green, and either veined or veinless. the achenes nearly fill the body of the perigynia. The total number of chromosomes in diploid cells (2n) is 106.[5]
Distribution and habitat
It has a global rank of G4, meaning apparently secure. It also has many local ranks in Canada and the US. Including, S4 in Quebec, meaning, again, apparently secure. A S3 rank in the Northwest Territories and Nunavut, meaning it is vulnerable. A S1 rank is found in Alaska and Manitoba, meaning critically imperiled. It also has a SH rank in Labrador, meaning possibly extirpated.[1] It is most commonly found in the months of July, August, and January.
