campanulate, 9-13 mm high, 8-12 mm broad; bracts 

 not imbricate, a few of the outer ones oblong, 

 acute or somewhat obtuse, herbaceous, the others 

 lanceolate, acuminate, chartaceous, all exposed 

 parts of the involucre glandular-scabrous or 

 tomentulose; ray-flowers wanting; disk-flowers 10 

 to 25; disk-corolla tubular-funnelform, 9-11 mm 

 long, the throat longer than the very slender 

 tube, puberulent on tube; lobes ovate, erect, 1- 

 1.5 (2) mm long, glabrous; style-branches long- 

 exserted, the slender appendage much exceeding the 

 stigmatic portion; achenes slenderly prismatic, 5- 

 6 mm long, densely villous; pappus about equaling 

 corolla, soft, dull white (adapted from Hall 

 1928) . 



3. LOCAL FIELD CHARACTERS: The uniform absence of 

 ray-flowers, and presence of tomentum on the 

 stems, separates Haplopappus macronema from all 

 other members of the genus found within the state. 

 Again, Haplopappus macronema var. macronema 

 differs from variety linearis by having leaves 

 that are oblong or oblanceolate, 3-6 mm wide and 

 not tomentulose; versus the narrower (less than 2 

 mm) somewhat tomentose leaves that are 

 characteristic of variety linearis . According to 

 Hall (1928), H. macronema var. macronema is most 

 closely related to H. suf fruticosus . This species 

 differs from H. macronema var. macronema by the 

 presence of ray flowers, and the lack of tomentum 

 on twigs. 



D. GEOGRAPHICAL DISTRIBUTION 



1. RANGE: Haplopappus macronema is found in the 

 states of California, Oregon, Nevada, Utah, Idaho, 

 and Colorado, and at the northern edge of its 

 range, in Montana. It is apparently much more 

 common to the south and west, and the population 

 in Montana is peripheral to the main range of the 

 species. 



2. CURRENT SITES: There is currently one verified 

 record for Haplopappus macronema in southwest 

 Montana. The site is on the east side of the East 

 Pioneer Mountains, on Storm Peak (001) , in 

 Beaverhead County, Montana. It was collected from 

 this site in 1920 (voucher specimen H. W. Elofson 

 (133) ) . This specimen is deposited at the Montana 

 State University Herbarium (MONT) . Working under 

 contract for the Natural Heritage Program in 1990, 

 Cedron Jones and Sarah Toubman relocated this
