4. Broadwater Co. A scattered tract on Lone Mt. five miles 

 south of Radersburg; R.4N RIE Sec. 7 SE 1/4. 



5. Broadwater Co. A scattered tract in rolling uplands with dry 

 balds in T.4N R.IW Sec. 15 NW 1/4 of NE 1/4; NE 1/4 of NW 1/4. 



In general, limestone larkspur prevailed in the most open and 

 exposed settings, at southern ends of the study area. It was 

 replaced at higher elevations by D. bicolor ssp. bicolor . 



3. HISTORICAL SITES: None 



4. UNVERIFIED/UNDOCUMENTED REPORTS: We have not yet requested Dr. 

 Warnock to annotate all Montana specimens currently labelled as 

 D. andersonii and D. geyeri . Jim Vanderhorst has reviewed these 

 materials for their consistency to the Warnock treatment. The 

 multiple folders of D. bicolor at the three major herbaria (MONT, 

 MONTU, MRC) also need to be reviewed. 



5. AREAS SURVEYED BUT SPECIES NOT LOCATED: Most of the study area 

 harbored the common D. bicolor ssp. bicolor . 



E . HABITAT 



1. ASSOCIATED VEGETATION: In the study area, this taxon was only 

 found in grassland, and not in the extensive mountain mahogany 

 shrublands. Most of the associated vegetation types were 

 bunchgrass communities dominated by Elymus spicatus , but lower 

 elevation communities dominated by Stipa comata that barely 

 entered the study area were also associated. The associated 

 species included: 



Artemisia campestris 

 Bouteloua gracilis 

 Coryphantha missouriensis 

 Cryptantha celosioides 

 Elymus spicatus 

 Erigeron caespitosum 

 Koeleria macrantha 

 Kuhnia eupatorioides 

 Oryzopsis hymenoides 

 Penstemon aridus 

 Phlox caespitosa 

 Poa cusickii 

 Senecio canus 

 Stipa comata 



2. TOPOGRAPHY: This taxon is found in a wide range of topographic 

 positions and slope angles across the study area, corresponding 

 with sparseness of vegetation. It is on ridge crests, steep side 

 slopes, gentle rolling uplands, and gravelly valleybottom.
