SPECIES OF SPECIAL CONCERN 

 Lesquerella klausii 

 I. SPECIES INFORMATION 



A. CLASSIFICATION 



1. SCIENTIFIC NAME: Lesquerella klausii R, Rollins 



2. COMMON NAME: Divide bladderpod, Klaus' bladderpod 



3. FAMILY: Brassicaceae (=Crucif erae; Mustard Family) 



4. GENUS: The genus Lesquerella consists of 



approximately 75 species in North America, with 

 most of the species being concentrated in Mexico, 

 the southwestern United States, and the Rocky 

 Mountain and intermontane basin region of the 

 western United States (Rollins and Shaw 1973). 

 Dorn lists only four species of Lesquerella in his 

 1984 flora of Montana. However at least four 

 other species have either been newly described or 

 recently discovered in Montana, including L. 

 klausii . 



5. SPECIES: The earliest collections of Lesquerella 



klausii were most often determined as Physaria 

 qeveri . However Dr. Reed Rollins recognized that 

 there was a previously undescribed species amongst 

 these collections. Klaus H. Lackschewitz 

 discovered the species near Lewis and Clark Pass 

 in 1977, and the species was named in his honor 

 (adapted from Shelly 1988) . 



B. PRESENT LEGAL OR OTHER FORMAL STATUS 



1. FEDERAL STATUS 



a. U.S. FISH AND WILDLIFE SERVICE: None. 



b. U.S. FOREST SERVICE: In 1988 the Forest 



Service placed Lesquerella klausii in the 

 Watch Category (U.S. Department of 

 Agriculture 1988) . In 1991 this species was 

 dropped from consideration due to a decision 

 to drop all Watch species which actually 

 occurred on Forest Service lands (Lesica and 

 Shelly 1991b) .
