- Arundo stricta Timm, Mag. Naturk. Oekon. Meklenburgs 2: 235 (1795). Type: Germany: "Mechlenburg prope Malchin". Isotype in LE. - Calamagrostis stricta (Timm) Koeler, Descr. Gram.: 105 (1802). - Calamagrostis neglecta subsp. stricta (Timm) Tzvelev, Novosti Sist. Vyssh. Rast. 1965: 30 (1965).
28 (4x). - Europe, Far East (N), Canada, U.S.A., Greenland. - Numerous reports but some of these may belong to the other subspecies.
Not included: Reports of higher numbers, 2n = 42 (Alaska), 56 (Russia), 56-60 (Siberia-Far East), 70 (Europe, Russia, Siberia, Far East), and 84 (Japan). The tetraploid number (2n = 28) is by far the most frequently reported and the tetraploids seem to reproduce sexually. The higher numbers might be autopolyploids, they might refer to closely related allopolyploids, to hybrids, or some (or many) of them may be based on misidentifications.
Geography: Circumboreal-polar: NOR RUS SIB RFE ALA CAN GRL.
Notes: Tzvelev (1965, 1976) considered Calamagrostis stricta different from C. neglecta at the subspecific level, distinguished by glume length 3.5-4.2 mm and relatively long-pointed vs. 2.5-3.5 mm and short-pointed. He also accepted a C. neglecta subsp. micrantha (Kearney) Tzvelev (C. micrantha Kearney) from northeastern Siberia, the Russian Far East, and western North America, distinguished from the two others by spikelets 2-2.5 mm vs. >2.5 mm. Comparing northwestern North American plants with European plants (irrespective of name choice, C. neglecta or C. stricta), we find the American plants to have distinctly shorter and less pointed glumes, and thereby smaller spikelets, than European plants. Something for someone to study in the future. In the northern European material are found both plants with long-pointed and short-pointed glumes, and this difference does not seem to be connected to that between subsp. neglecta and subsp. groenlandica (the latter always with long-pointed glumes).
The range of subsp. neglecta is not clear, especially not in North America (outside Alaska and the Yukon Territory) and Greenland, due to insufficient separation from subsp. groenlandica. Only subsp. groenlandica has been reported from Iceland and observed in Icelandic material (O) but the sample studied should be extended. Internal note: Collections in 2010 should be checked for affinity of Icelandic material.
