specimen remains uncertain (Lesica and Shelly 

 1991) , and brief surveys for this population in 

 1989 by Sarah Mathews for the Montana Natural 

 Heritage Program were unsuccessful. Aquileqia 

 f lavescens was observed in flower by this author 

 at Aspen Campground, on the Boulder River, on 5 

 June 1991. Further survey work will be necessary 

 to locate and try to verify this record. 



As stated above, this site is included on the 

 state map (p. 6) and information on the site can 

 be found in the Element Occurrence records. 

 Section V, p. 25. However, since an exact 

 location of this occurrence is not known, a 

 U.S.G.S. topographic is not included. Also, this 

 site will not be referenced in much of the 

 discussion that follows. 



AREAS SURVEYED BUT SPECIES NOT LOCATED: The 

 following areas were surveyed by the author for A, 

 brevistyla because the habitat appeared to be 

 suitable on the topographic maps, but the species 

 was not located within them. The actual areas 

 surveyed may be smaller than the portions of the 

 sections indicated.

Areas marked by a star contained A. f lavescens . 



In addition, Wayne Phillips (Ecologist, Lewis & 

 Clark National Forest) surveyed for A. brevistyla 

 in drainages of Little Snowy Mountains and in the 

 Crystal Lake area of the Big Snowy Mountains in 

 1991 without result. 



E. HABITAT 



1. GENERAL DESCRIPTION AND ASSOCIATED VEGETATION: 



Aquileqia brevistyla occurs in open woods and on 

 stream terraces at mid-elevation in the mountains. 

 Populations in Montana occur at elevations from 

 5000-6000 feet (1525-1830 m) (Lesica and Shelly
