Element Name: Haplopappus macronema Gray ssp. linearis (Rydb.) 



Hall 



Common Name: Discoid goldenweed 



Range: The subspecies is endemic to northwest Wyoming and 

 southwest Montana. In Montana it is known from Beaverhead, 

 Madison, Meagher and Silver Bow counties. 



Element Rank: G4T7/S2 



Federal Status: None 



Local Occurrence: I located two populations of H_^ macronema 

 linearis in moist steppe in the Moose Town/Burton Park area (Fig 

 7). The Burton Park population was estimated to be fewer than 

 300 plants, while the Moose Town population was estimated to be 

 500-1,000 plants. Associated plant communities were Artemisia 

 tridentata / Festuca idahoensis and Potentilla fruticosa / Festuca 

 idahoensis . 



Comments: Although there is an abundance of apparently 

 ^ appropriate habitat in the study area, I located only tv/o 



populations of H^ macronema linearis . Many of the plants at the 

 Burton Park site had been broken due to livestock trampling. 

 However, the plant seems to respond positively to disturbance at 

 the Moose Town site, being most common near fences and along 

 roads . 



Element Name: Ranunculus verecundus Robins. 



Common Name: Modest buttercup 



Range: Alaska south to Oregon, Idaho and Wyoming. In Montana 

 this species is known from Glacier National Park and the Highland 

 and Anaconda ranges in Beaverhead, Deer Lodge and Madison 

 counties . 



Element Rank: G5/S1 



Federal Status: None 



Local Occurrence: I located one population of R^ verecundus in 

 wet tundra on the west shoulder of Table Mountain (Lesica 1992, 

 Fig. 5) . Associated plant community was Deschampsia 

 cespitosa / Caltha leptosepala . Population size was estimated to 

 be 200-500 plants.
