| Juncus ranarius var. ossoraicus Novikov | |
| Publ. & Syn. | Novikov, Novosti Sist. Vyssh. Rast. 19: 53 (1982). Holotype (VLAD): Russian Far East: Kamtchatka, "distr. Karaginski, ad pag. Ossora", 06. Aug. 1976, leg. S. Kharkevicz and T. Bucz. - Juncus ambiguus var. ossoraicus (Novikov) Novikov, Sosud. Rast. Sovet. Dal'nego Vostoka 1: 63 (1985). |
| Notes | Elven and Murray: Variety ossoraicus is a specialist of geothermal sites, known from a few sites on the Chukchi Peninsula (East Chukotka) and the Seward Peninsula (western Alaska). The Alaskan specimens (ALA; Serpentine and Pilgrim Hot Springs) are more similar in diagnostic floral characters to Juncus bufonius than to J. ranarius. Variety ossoraicus may be acceptable as an ecotypical variety but perhaps not of J. ranarius. |
| Chromosomes | 34 30-38. - Europe, Siberia, Asia (C), Canada, U.S.A. (W), Greenland. - Numerous reports, partly for J. bufonius. Not included: A report of 2n = 52 for J. nastanthus from the Chukchi Peninsula (Yurtsev et al. 1975b). This is above the normal ploidy range for J. ranarius. |
