Potentilla diversifolia G5T3T4SH 

 var . multisecta 



This taxon was collected from an area within the general 

 vicinity of the southern Big Belt Mountains along Rocky 

 Canyon, "_ miles north of Belgrade" but has not been seen in 

 Montana for almost 90 years. The area of the original 

 collection corresponds with private property within the 

 boundaries of lands administered by the U.S. Forest Service. 

 It is reported from dry rocky slopes and ridges in the 

 subalpine and alpine zones at 7000-9000' elevation. 

 Flowering occurs in late May through June. The habitat 

 profile may need more refinement. 



Salix serissima G4S1 Watch 



This willow grows in low elevation fen habitat including a 

 site ca. 10 miles east of the Big Belt Mountains near White 

 Sulphur Springs. It might possibly be found in the Big Belt 

 Mountains in swamps and fens in the valleys and foothills at 

 elevations of 4500-5300', though no habitat resembling the 

 White Sulphur Springs setting was found. It flowers in 

 June, and the fruit matures in July through September. The 

 confidence level of the habitat is high and of the species 

 occurrence is low. 



Salix wolf ii var. wolf ii G4T4S1 Sensitive 



This willow might occur in the Elkhorn Mountains in rocky 

 clay-loam soils in wet meadows, or more often in riparian 

 areas in the montane to subalpine zones at elevations of 

 6500-9000'. Fruit matures in July to August. The 

 confidence level of the habitat profile is medium while that 

 of the species occurrence is low. 



Sphenopholis obtusata G5T5S1 

 var. major 



This grass has not been collected in Montana since 1949, but 

 might occur in the Elkhorn and Big Belt Mountains in 

 grasslands in the valleys and on the plains at 3000-5000' 

 elevation. The fruit matures in July and August. The 

 confidence level of the habitat and of the species 

 occurrence is low. 



Townsendia spathulata G3S3 - 3C 



This species occurs on low elevation limestone ridges at the 

 eastern edge of the Elkhorn Mountains in the Limestone Hills 

 on land administered by BLM. It might possibly be found 

 elsewhere in the Elkhorn and Big Belt Mountains on open 

 rocky limestone-derived soils of slopes and windswept 

 ridgetops in the valley and foothill zones at elevations of 

 4500-6400'. Flowering occurs in May to early June. The 

 confidence level of the habitat profile is high while that 

 of the species occurrence is medium.
