STUDY AREA DISTRIBUTION: This species was documented in one 

 location above lower Home Creek. It was not systematically surveyed for 

 because it was not recognized as a new addition to the state flora at the time of 

 the fieldwork. Much potential habitat appears to exist. However, the species 

 was not seen elsewhere during the course of the study and is not likely to be 

 common in the area. 



D. HABITAT 



1. ASSOCIATED VEGETATION: Within the study area, £vax ;77-o///e/-a was 

 found at a single location: a sparsely-vegetated site within sagebrush 

 grassland. The central part of the site had less than 10% vegetative cover. 

 Plants occuiTed near the periphery of this open area. Associated species 

 include Gutierrezia sarolhrae. Allium textile, and Plantago patagonica. 



2. TOPOGRAPHY: The site is flat, located at the base of a small butte in 

 otherwise rolling upland terrain above lower Home Creek. 



3. SOIL RELATIONSHIPS: £vax/7ra///e/-a was growing on light-colored 

 alkaline soil at the base of a butte in an area that is elsewhere well-vegetated 

 with sagebrush grassland. The soil may be colluvial material from the butte 

 strata. 



POPULATION BIOLOGY AND SPECIES BIOLOGY 



1. PHENOLOGY: Both flowering and vegetative individuals were seen in mid 

 June. 



2. POPULATION SIZE, STRUCTURE AND TREND: No estimate of 

 population size was made at the time of collection. At least 200 individuals 

 were present (ca. 20 were collected with no significant impact to the 

 population). All individuals were near the lower end of the height range for the 

 species (less than 3 cm tall). 



3. REPRODUCTIVE BIOLOGY 



a. TYPE OF REPRODUCTION: This annual species reproduces by 

 seed. 



b. POLLINATION BIOLOGY: Wind pollination likely. 



c. SEED DISPERSAL AND BIOLOGY: UnknowTi.
