Revision as of 20:13, 16 December 2019
Plants densely cespitose, tuft-forming; rhizomes inconspiuous. Culms 5–30(–40) cm. Leaves involute, 0.25–1.5(–2) mm wide. Pistillate scales light to dark brown, ovate, shorter than to as long as perigynia, apex obtuse to acute, apex and distal margins frequently hyaline, scarious. Perigynia ascending to spreading even reflexed at maturity, light green becoming straw colored, 3–4(–5) (including stipe) × 1–1.3 mm; beak dark brown, much shorter than body of perigynium. Stigmas 2(–3). 2n = 62 (Chukotka).
Phenology: Fruiting Jul–Aug.
Habitat: Moist meadows, stream banks, seeps, snowbeds and areas irrigated by meltwater
Elevation: 10–4000 m
Distribution
Alta., B.C. Yukon, Alaska, Calif., Colo., Idaho, Mont., Nev., Oreg., Utah, Wash., Wyo., Eurasia (Japan, Russia).
Discussion
There is as much variation within the Rocky Mountain Carex crandallii as between C. crandallii and C. micropoda of Alaska and British Columbia. J. A. Calder and R. L. Taylor (1968) reported a weak distinction between a predominately distigmatic coastal race (“micropoda”) and a tristigmatic one (“pyrenaica”) from the interior. T. V. Egorova (1999) illustrated the shapes of perigynia for C. pyrenaica and C. micropoda, and the differences are consistent with what others have noted. Nevertheless, until a more reliable set of characters is found to distinguish these two taxa, all of the North American plants shall be treated as C. micropoda. W. A. Weber and R. C. Wittmann (1992) maintain the North American plants distinct from the European C. pyrenaica at the rank of species, a view that is accepted here. A thorough, worldwide review of relationships among taxa is warranted.
