 numbers are indicated in parentheses after the 

 site names; these correspond to the occurrence 

 numbers provided in the tables and computer print-

3. HISTORICAL SITES (MONTANA): One historical 

 location of C. passerinum is documented by a 

 voucher specimen. This collection was made in 

 1894, in the vicinity of Columbia Falls (Flathead 

 County) . It is unknown whether the species is 

 still extant in this area. The location 

 information is so vague that the record is not 

 mapped on the Natural Heritage Program topographic 

 maps. The existing information is contained in 

 the computer print-out (p. 31, occurrence no. 



009) . 



4. SITES NOT RECENTLY SURVEYED (MONTANA): 

 C ypripedium passerinum has been documented from 

 one site in Glacier National Park. This 

 occurrence was studied by Peter Lesica in 1983. 

 The location, legal description, latitude and 

 longitude, elevation, and USGS topographic 

 quadrangle name for this site is provided in Table 

 IB, p. 7. 



5. UNVERIFIED/UNDOCUMENTED REPORTS (MONTANA): 

 Cypripedium passerinum has been reported in the 

 Straight Creek drainage in the Front Range; a 

 photograph of a plant in late flower was 

 identified by Wayne Phillips (pers. comm.). The 

 exact location is unknown, and the site should be 

 verified in 1989. The existing information is 

 contained in the computer print-out (p. 34, 

 occurrence no. 012) . 



6. AREAS SURVEYED BUT SPECIES NOT LOCATED: Field 

 surveys on the Lewis & Clark National Forest in 

 1988 emphasized thorough searches along 

 tributaries of the Sun River in the Front Range. 

 Drainages which were surveyed on foot, but in 

 which no sites for C. passerinum were found, 

 include: 



a. Cutreef Creek (T21N, R9W, Sections 26, 27, 35, 

 36) . 



b. Leavitt Creek (T21N, R9W, Sections 8, 17).
