CEGL001952 Minuartia obtusiloba - Lupinus sellulus Alpine Fell-field
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Twin-flower Sandwort - Donner Lake Lupine Alpine Fell-field
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs above treeline (alpine zone) at Mount Rainier. In the Olympics, it can occur at subalpine elevations on harsh, rocky sites. Sites are flat to gentle slopes with well-drained, often rocky soils. This association is found in patches or strips among stones and/or gravel. Lupinus sellulus var. lobbii is typically prominent to codominant. Erigeron aureus and/or Minuartia obtusiloba are also typically prominent to codominant. Festuca saximontana in the Cascades or Festuca brachyphylla in the Olympic Mountains, along with Carex phaeocephala, Luzula spicata, Penstemon procerus, Phlox diffusa, and Solidago simplex var. nana are frequently present.

Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Crawford et al. (2009) combine this association (CEGL001952) with ~Erigeron aureus - Lupinus sellulus Alpine Fell-field (CEGL001961)$$. Part of the variation of the Phlox-Carex community described by Schreiner (1994) is included here.
