CURRENT SITES (GALLATIN NATIONAL FOREST) : Agoseris 

 sp. nov. is recently documented (1989) from one 

 site on the Gallatin National Forest, and was 

 collected in 1980 from a second site on the Forest. 

 The location of the population found in 1989 is 

 provided in the element occurrence print-out on p. 

 40, and is indicated on the map on p. 41. Field 

 surveys were conducted by the author on 31 July 

 1989 and 10 August 1989. 



HISTORICAL SITES: The population of Agoseris sp. 

 nov. represented by the 1980 collection was the 

 focus of the 1989 field survey by the author. The 

 collection ( Lackschewitz 9421 , MONTU) was made in 

 the vicinity of Sunlight Peak in the Crazy 

 Mountains. The survey was not successful, due to 

 logistical difficulties encountered in trying to 

 reach the site (the trail is washed out just below 

 the pass from the Sunlight Creek drainage over to 

 Sunlight Lake) . There was insufficient time for a 

 second attempt to reach the area from the east 

 side. The existing information on this population 

 is provided in the element occurrence print-out on 

 p. 42. 



E . HABITAT 



1. ASOCIATED VEGETATION: Agoseris sp. nov. occurs in 

 wet meadows at high elevations. The site found in 

 1989 occurs in openings of Pinus albicaulis 

 (whitebark pine) stands, with grasses, sedges and 

 the following forbs: 



Antennaria alpina (alpine pussytoes) 

 Polygonum bistortoides (American bistort) 

 Potentilla diversifolia (diverse-leaved cinquefoil) 

 Veronica wormskjoldii (American alpine speedwell) 



2. TOPOGRAPHY AND SOILS: At the currently documented 

 site, Agoseris sp. nov. occurs on level ground at 

 2850 m. (9500 ft.). The subalpine meadow soils are 

 saturated throughout the growing season. 



POPULATION DEMOGRAPHY AND BIOLOGY 



1. POPULATION SIZE AND CONDITION: The extent of the 

 Agoseris sp. nov. population in the Haystack and 

 Monument Peaks vicinity (occurrence 007) is unknown 

 at this time. The species was found during a 

 survey for another species, and time was not 

 available for a full survey of the site. Much 

 suitable habitat was observed in the area. 



2. REPRODUCTIVE BIOLOGY: Many Agoseris species
