Discussion

Recent treatments of the Carex crinita species complex have not discriminated C. crinita var. brevicrinis. Genetic data coupled with morphologic data have demonstrated that C. crinita var. brevicrinis is distinct from C. crinita var. crinita. Although the taxa are predominantly allopatric, in New Jersey they may be sympatric and syntopic. Carex crinita var. brevicrinis is sympatric and syntopic over a significant portion of its distribution with C. mitchelliana; hybridization between the two taxa has been reported.
