I. SPECIES INFORMATION 

 A. CLASSIFICATION 



1. SCIENTIFIC NAME: Aqoseris lackschewitzii D. 

 Henderson & R. Moseley. 



2. COMMON NAME: Pink agoseris. 



3. FAMILY: Asteraceae (= Compositae , Sunflower 

 Family) . 



4. GENUS: The flora of Montana has elements from the 

 Rocky Mountains, Great Plains, and the Pacific 

 Northwest. Rydberg (1922) recognized 33 species 

 of Aqoseris in the Rocky Mountains and adjacent 

 plains, which reflects the large amounts of 

 morphologic variation present in this genus. 

 Hitchcock and Cronquist (1973) list seven Aqoseris 

 species in the Pacific northwestern states. Dorn 

 (1984) describes four species as present in 

 Montana: three perennials (A. qlauca (Pursh) Raf., 

 A. aurantiaca (Hook.) Greene, and A. qrandif lora 

 (Nutt.) Greene) and one annual (A, heterophylla 

 (Nutt.) Greene). Aqoseris lackschewitzii has been 

 described only recently and has not been included 

 in any flora. 



5. SPECIES: Henderson et al. (1990) described A. 

 lackschewitzii as an Aqoseris that has pink 

 flowers from anthesis (Figure 1, p. 2). This 

 differs from two closely related species: A. 

 aurantiaca and A. qlauca . A. aurantiaca has 

 orange flowers, and A. qlauca has yellow flowers. 

 Both may age or dry to a pinkish color, but are 

 never pink at anthesis. Additionally, ecological 

 requirements of the species differ; Aqoseris 

 lackschewitzii is found in locations moister than 

 either of the other two species (Henderson et al. 

 1990) . 



B. PRESENT LEGAL OR OTHER FORMAL STATUS 



1. FEDERAL STATUS 



a. U.S. FISH AND WILDLIFE SERVICE: This species 

 currently has no status under the U.S. 

 Endangered Species Act of 1973 (U.S. 

 Department of Interior, Fish and Wildlife 

 Service 1990) . Because the species has been 

 described only recently, it has not been 

 evaluated for status under the Endangered
