| Publ. & Syn. | Juncus leucochlamys var. borealis Tolm., Fl. Arct. URSS 4: 21 (1963). Holotype (LE): Siberia, "In valle fluminis Medveshja, infra ostium fl. Bychy", 06. Aug. 1935, leg. F.B. Sambuk. - Juncus leucochlamys subsp. borealis (Tolm.) Novikov, Sosud. Rast. Sovet. Dal'nego Vostoka 1: 74 (1985). |
| Notes | Solstad and Elven: In Europe, Juncus leucochlamys is restriced to northwestern Iceland and Svalbard (Elven et al. 2010). Elven: We do not yet have data for evaluation of a reported northern race ("borealis") within J. leucochlamys. The wide polymorphy observed in the material from northeastern Asia and northwestern North America does not, however, support a geographically distinct race. Kirschner et al. (2002b) synonymised var. borealis with subsp. leucochlamys. |
