C. Major plant group: Dicotyledoneae. 



D. History of Icnovledge of taxon: The earliest known 

 specimen is a recent collection ( Lackschewitz 8487 

 29 July 1978, at the summit of Headquarters Pass, in 

 the Flathead Range) , deposited at the University of 

 Colorado, University of Montana, and New York 

 Botanical Gardens, representing the paratype 

 collection. The type and paratype collections 

 together represent a total of 18 plants, upon which 

 the description is based. The species was named for 

 its discoverer, Klaus Lackschewitz. 



E. Comments on current alternative taxonomic 

 treatments: Primary taxonomic references for the 

 Eriqeron genus of the Pacific Northwest region 

 (Hitchcock and Cronquist 1984) and of the country 

 (Spongberg 1971) preceded description of Eriqeron 

 lackschewitzii , Dorn (1984) treated it as a synonym 

 of E. ochroleucus. Nesom (1989, and pers. commun. 

 to Kerstetter) has made a revision of his treatment 

 which makes Eriqeron lackschewitzii synonymous with 

 £. ochroleucus . 



Taxonomic research is being pursued as part of this 

 status review, conducted by Tulli Kerstetter at 

 Montana State University. A progress report of this 

 work is submitted separately (Kerstetter 1993) and 

 will be completed in 1994. The distinction 

 between E. lackschewitzii and other related species 

 may warrant differentiation at the variety level 

 (Kerstetter pers. commun.). The published 

 distinctions do not seem adequate in themselves for 

 differentiating £. lackschewitzii . The study 

 underway will review morphological distinctions, as 

 well as: 



- chloroplast DNA 



- chromosome number 



- isozyme analysis 



Eriqeron lackschewitzii material keys out to E. 

 ochroleucus in the floristic references mentioned 

 above. Other related taxa being studied include 

 E. radicatus, E. simplex , and tentatively E. 

 qrandiflorus . 



A complete summary of Eriqeron lackschewitzii 

 taxonomic standing will be prepared in 1994 as an 

 update to this report.
