This distinct northeastern species is unlikely to occur in Ky. accordign R. Naczi and A. Reznicek (pers. comm.). It is concentrated in the Great Lakes region but extends south at least to c Ill., c. Ind. and c. Ohio (K). There appear to be verified records from e. Tenn. (Knox Co.) and perhaps w. Tenn. (Tipton Co.); see SERNEC (2024). C. alopecoidea was mapped in Ky. by FNA 23, but colls. have not been seen or verified. Colls. have been reported from BULL (KY--mislaid?), MADI (BEREA--in processing?) and MORG (sent to MICH?). C. alopecoidea (2n = 68) is close to conjuncta, but differs in its sheaths, with smooth fronts and with faint or absent abaxial veins (FNA 23). Also, it sometimes has a simpler non-compound inflorescence as in section Phaestoglochin.
