I.l.D. History and knowledge of taxon: Prior to 

 1988, Claytonia lanceolata var. f lava was 

 recently documented from four sites: one in 

 Idaho (Fremont County) , one in Wyoming 

 (Fremont County; four subpopulations) , and 

 two in Montana (Beaverhead and Gallatin 

 counties) . In addition, it was historically 

 known from two locations in Montana (Deer 

 Lodge and Jefferson counties). In 1988, the 

 Montana Natural Heritage Program (MTNHP) , 

 under sponsorship by the U.S. Fish and 

 Wildlife Service (Section 6 Project Agreement 

 SE-5-P) , conducted field surveys for the 

 taxon. Field work was conducted in May and 

 June by the author, with assistance from 

 Peter Lesica (University of Montana) , Lisa 

 Schassberger (MTNHP) , Ken Scow (Helena) , and 

 Jan Nixon (Bozeman) . Surveys were conducted 

 in Beaverhead, Deer Lodge, Gallatin, 

 Jefferson, and Silver Bow counties. 



The two recently documented populations in 

 Montana were surveyed in detail, and were 

 found to be more extensive than previously 

 known. In addition, it is believed that 

 surveys in the vicinity of the two historical 

 locations resulted in their rediscovery. One 

 previously unrecorded population was found. 

 Thus, the taxon is currently known from a 

 total of seven occurrences. All data and 

 photos are from 1988, except where noted.
