Haplopappus macronema var. macronema 



I. SPECIES INFORMATION 



1. SCIENTIFIC NAME: Haplopappus macronema var. 

 macronema Gray. 



2. COMMON NAME: discoid goldenweed. 



3. FAMILY: Asteraceae (= Compositae, Sunflower 

 Family) . 



4. GENUS: According to Hitchcock et a^. (1955-1969) 

 there are approximately 150 species in the genus, 

 equally distributed between North and South 

 America. Those in North America occur principally 

 in the western cordillera. The genus seems to 

 constitute a natural group, and the species are 

 mostly well defined, their limits only rarely 

 blurred by hybridization. 



5. SPECIES: There are currently 14 species of 

 Haplopappus known from Montana. Four of these 

 species (H. aberrans . H. nanus . H. pyqmaeus . H. 

 macronema var. macronema ) have a limited 

 distribution within the state. Haplopappus 

 macronema var. linearis is more common in the 

 state, and is often misidentif ied as Chrysothamnus 

 parryii . It differs from variety macronema by 

 having linear leaves 2 mm or less wide, which are 

 somewhat tomentulose. In comparison, variety 

 macronema has leaves that are oblong or 

 oblanceolate, 3-6 mm wide and not tomentulose. 



Unless otherwise stated, H. macronem a will refer 

 to variety macronema throughout the rest of this 

 report.
