thick-rooted, grayish-hairy to greenish, multistemmed 

 perennial 2-8 dm. tall; leaf blades 2-6 cm long, 

 reniform to ovate-deltoid, from rather shallowly 3-5 

 lobed to merely crenate; pedicels usually shorter 

 than the calyx; calyx bracteoles usually 3, linear; 

 petals 1-2 cm long, apricot-ping to reddish; carpels 

 about 3 mm long, rugose-reticulate only on the lower 

 (indehiscent) third, mostly 1-seeded. 



LOCAL FIELD CHARACTERS: Sphaeralcea munroana is 

 distinguishable by its apricot flowers and the 

 stellate-pubescence along the stem and leaves. 



D. GEOGRAPHICAL DISTRIBUTION 



1. RANGE: Sphaeralcea munroana occurs from southcentral 

 British Colombia to Western Montana, into California 



and Utah. 



2. CURRENT SITES: Sphaeralcea munroana was found 

 frequently in the western portion of Centennial Valley 

 along the road and hillsides. It was located 

 approximately 3 miles west of Monida and found 

 extensively near the Lima dam. It is known in Montana 

 only from the Centennial Valley. 



E. HABITAT 



1. ASSOCIATED VEGETATION: Sphaeralcea munroana occurs on 

 open sagebrush ( Artemisia tridentata ) grassland 

 ( Festuca idahoenis ) along with the following forbs: 



Eriqeron caespitosus (gray daisy) 

 Chrysothamnus viscidif lorus (green rabbitbrush) 

 Koeleria cristatum (June grass) 

 Hordeum jubatum (Foxtail barley) 

 Poa pratensis (Kentucky bluegrass) 

 Poa cusickii (Cusick's bluegrass) 



2. TOPOGRAPHY AND SOILS: Sphaeralcea munroana 



occurs on south facing or open slopes along hillsides 

 or roads. It was found to occur in red calcareous 

 soils. 



\ POPULATION DEMOGRAPHY AND BIOLOGY 



1. POPULATION SIZE AND CONDITION: Sphaeralcea munroana 

 populations seem to be expanding from the roadsides to 

 the midslopes of the hillsides. The populations 

 observed were healthy with no evidence of disturbance. 



G. REPRODUCTIVE BIOLOGY: S phaeralcea munroana reproduces by 

 seed resulting in a taproot perennial.
