A. geyer 



slightly arcuate to somewhat lanate, 1-celled, the lov/er 

 suture not at all intruded (Hitchcock et al . 1984). 



LOCAL FIELD CHARACTERS: The Astrag a lus lotiflorus closely 

 resembles A. geyeri in its subacaulescent growth form, and 

 its affinity to sandy habitat in eastern Montana. However ^ 

 it is not annual as A. geyeri . It does not have the 

 inflated, half-ellipsoid, glabrous pods of A. geyeri . It 

 does not have the basifixed hairs on leaves and stems; a 

 character which cannot be discerned without a hand lens 

 (lOX). 



GEOGRAPHICAL DISTRIBUTION 



1. RANGE: Geyer's milkvetch ranges from southern Washington to 

 California and Nevada, extending east to Montana, Wyoming 

 and Utah. In Montana, most of its sites are in the Pryor 

 Mountains, with the exception of the Garfield County 

 collection and historic collections from Dawson and Custer 

 counties . 



2. CURRENT SITES: All five other current records for this 

 species are from the Pryor Mountains in Carbon County. 



3. HISTORICAL SITES: It was collected in the vicinity of 

 Glendive (Dawson County) and Miles City (Custer County) at 

 the turn of the century. 



UNVERIFIED/UNDOCUMENTED REPORTS: None,
