CEGL001956 Caltha leptosepala - Polygonum bistortoides Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: White Marsh-marigold - American Bistort Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This type is described from one study of subalpine and alpine meadows of the Sangre de Cristo Mountains of northern New Mexico, where it occurs in wetlands. The association is based upon 2 plots of data, each of which could legitimately be placed in a different association based upon species composition and abundance. These plots represent stands of subalpine wet meadow vegetation types, found in small areas within the predominant spruce-fir forest. Elevations range from 2930 to over 3200 m (9600-10,500 feet). The soils of both stands were reported to be saturated year-round, with one stand having standing water much of the year. Both stands are characterized by dominance of herbaceous species, primarily Deschampsia cespitosa, Caltha leptosepala, and Polygonum bistortoides. Other species present in less abundance include Swertia perennis, Pedicularis groenlandica, Ligusticum porteri, Phleum alpinum and Veronica wormskjoldii. This association is probably not a valid type, and the plots representing it should be compared to data from other wet meadow, herbaceous types from elsewhere in the Southern Rockies.

Classification Comments: The association is based upon two plots of data, each of which could legitimately be placed in a different association based upon species composition and abundance. This association is probably not a valid type and the plots representing it should be compared to data from other wet meadow, herbaceous types from elsewhere in the Southern Rockies, particularly associations dominated by Deschampsia cespitosa. Caltha leptosepala is a perennial forb known from high montane meadows and bogs in the Rocky Mountains and one report from California. Polygonum bistortoides shares a similar habitat, and its distribution includes the higher elevations of the western mountains.
