F. Assessment and management recommendations: Aster paucif lorus 

 was not relocated. It occupies primary range where it occurs 

 along watercourses, and its recommended status hinges on 

 whether or not it is affected by livestock use. If it is 

 found on Custer National Forest in the Cave Hills, and if it 

 decreases under most or all grazing conditions, then 

 designation as sensitive is appropriate. In the interim, it 

 is recommended for recognition as a watch species by Custer 

 National Forest.

 A. Description 



1. General description: Single-stemmed perennial herb, 

 mostly 20.3-40.6 cm (8-16 in) tall, with little or no 

 branching, conspicuously to weakly covered by matted white 

 hairs (hence the reference to "dusty" in the species' common 

 name), glandular on the upper part of the stem if at all. 

 Leaves 1.9-12.1 cm (3/4 - 4 3/4 in) long and 1-3 times 

 pinnately divide, appearing thick and rounded due to lower 

 margins curled down inward. Heads 1-several in an open 

 cluster. Ray flowers lacking, disk flowers perfect and 

 fertile, the corollas creamy white, sometimes with shades of 

 pink (from Hitchcock et al. 1984). 



2. Technical description: Single-stemmed, taprooted 

 perennial herb, mostly 2-5 dm tall, simple or sparingly 

 branched, variably tomentose, sometimes glandular especially 

 upward. Leaves 2-12 cm long and 1- to 3-pinnatif id, the 

 thickish segments characteristically curled and so oriented 

 that the leaves do not look flat; upper leaves usually less 

 dissected than the larger and often tufted lower one; heads 1- 

 several in a corymbiform, flat-topped inf loresence, of the 

 lateral branches overtopping the central axis, involucre 7-16 

 mm high, glandular-hairy or merely glandular; pappus scales 

 mostly 10-16, often biseriate; receptacle naked; achenes 

 somewhat club-shaped and angled (after Great Plains Flora 

 Association 1986, Hitchcock et al. 1984.) 



3. Diagnostic characteristics: Douglas 1 dusty maiden vaguely 

 resembles false boneset (Kuhnia eupatorioides ) in having 

 rayless white flower heads. They occupy similar pioneer 

 habitat. But Douglas' dusty maiden has dissected leaves, 

 while false boneset has entire to slightly toothed leaves. 

 They differ technically in that false boneset has a pappus of 

 capillary bristles, while Douglas' dusty maiden has a pappus 

 of scales. There are few species with which it might be 

 confused in the study area. Our variety is C. douqlasii var. 

 achilleaefolia . the only variety that reaches the Great Plains.
