Rhinanthus minor subsp. minor | |
Publ. & Syn. | L., Amoen. Acad. 3: 54 (1756). Type not designated (Jarvis 2007: 793). |
Notes | All records of subsp. minor from the Arctic are dubious. Elven et al. (2005) did not accept this race to reach the Arctic in Norway. Kuzeneva (1966) mapped it (together with Rhinanthus groenlandicus) from the Arctic in the Murman area in northwestern European Russia. Hultén and Fries (1986) accepted it to reach the Arctic in Iceland but not in Greenland. Böcher et al. (1978) accepted it from Greenland. |
Chromosomes | 14 14+8B (2x). - Europe (N, C), Canada, U.S.A. (NE), Greenland. - Numerous reports for "borealis", "groenlandicus", and "minor". Witsch (1950) stated B-chromosomes to be a constant part of the genome of Rhinanthus (as Alectorolophus). The many reports of 2n = 22 then represent a set with 2n = 14 plus 8 B-chromosomes. Whether the northwestern North American plants reported with 2n = 14 represent plants without B-chromosomes, or plants where the B-chromosomes have not been counted, is not known. Taylor and Mulligan (1968), however, stated regular meiosis without B-chromosomes in 2n = 14 "borealis" from British Columbia. If so, the absence of B-chromosomes is a difference of Pacific vs. Atlantic (European) plants. |
