Basal leaves linear-oblanceolate to narrowly 

 oblanceolate, 20-60 nun long, 1.2-3 mm wide, 

 gradually narrowed to a petiolar region. Margins 

 entire, cauline leaves 5-10 and similar to the basal 

 leaves, slightly reduced upwards or not, extending 

 fully halfway up the stem; leaves densely to 

 sparsely pubescent with a mixture of spreading and 

 appressed or ascending trichomes up to 3 mm long, 

 long-ciliate near the petiole base. Heads solitary; 

 involucres shallowly hemispheric, 12-17 mm wide 

 (pressed) , 6-8 mm high; phyllaries in ca. 3 equal 

 series, herbaceous, green, often with a golden 

 midvein, narrowly lanceolate with acuminate, loose 

 or reflexed tips, 0.5-1 mm wide, 5-8 mm long, 

 densely white-villous, the trichomes usually with 

 blackish-purple crosswalls, at least near the base- 

 Ray flowers fertile, 30-68 in l(-2) series, 

 apparently somewhat erect, 7.8-11.3 mm long, the 

 tubular portion 1.8-2.5 mm long, conspicuously 

 pubescent with both seriate and long uniseriate 

 trichomes, ligules narrowly obovate, 1.6-3 mm wide, 

 not reflexing or curling, drying light lilac to 

 purple, 4-7 veined, the margins slightly inrolling, 

 apex with 2-3 shallow to deep notches; style 

 branches 0.8-1.1 mm long, partially included within 

 the tube. Disk corollas yellow, tubular, slightly 

 indurated, pubescent, lobes 0.6-0.9 mm long, erect; 

 anther 0.7-1 mm long, with lanceolate apical 

 appendages, style branches 0.7-1 mm long, including 

 the deltate to shallowly triangular collecting 

 appendages. Achenes oblong-obovate, radially 

 compressed, tan, with 2 thin ribs, strigose with 

 long, untwisted, duplex trichomes; carpodium of 5-7 

 rows of cuboidal cells with a lower, inner row of 

 subsidiary cells' pappus of ray and disc flowers 

 similar, of 15-24 relatively thick but extremely 

 brittle bristles, ca. 3\4 as high as the disc 

 corollas but somewhat uneven (from Nesom and Weber 

 1983) . 



C. Local field characters: E. lackschewitzii differs 



from E. simplex in having basal leaves which are not 

 spathulate and well-demarcated but are instead 

 linear-oblanceolate to narrowly oblanceolate, and 

 having only 30-68 ray flowers instead of 50-125. It 

 also lacks conspicuously glandular trichomes (from 

 Nesom and Weber 1983) . In addition, E. simplex 

 comes from a rhizhome which is usually horizontal, 

 while £. lackschewitzii is taprooted, and it is 

 found in more protected sites than E. lackschewitzii 

 (Kerstetter pers. commun.).
