long as the fusiform, finely striate body 

 (adapted from Hitchcock et al. 1969). 



3. LOCAL FIELD CHARACTERS: The perennial habit of 



Juncus hallii along with its apparently lateral 

 inflorescence, its few (1-7) flowers per cluster, 

 well developed upper leaf blades, and retuse 

 capsules should distinguish it from other Juncus 

 species in Montana (Figure 11) . It is also 

 necessary to confirm that its seeds are 

 appendanged, to distinguish it from J. parrvi . 

 This usually cannot be done without a dissecting 

 scope. Only J. nevadensis has been reported to 

 occur with J. hallii . Juncus nevadensis is 

 distinguished by its obviously terminal 

 inflorescence (i.e., far surpassing the leaf 

 blades and the involucral bracts) , septate leaves, 

 unnotched capsules, and unappendaged seeds. 



D. GEOGRAPHICAL DISTRIBUTION 



1. RANGE: Juncus hallii occurs within the Rocky 



Mountains from southwestern Montana to Colorado 

 (Hitchcock et al. 1969). 



In Montana it is 

 known from nine 

 localities in 

 Madison, Meagher, 

 Powell, and Silver 

 Bow Counties 

 (Figure 13) , 

 including the 

 Lincoln District 

 of the Helena 

 National Forest. 



Juncus hallii 



CURRENT SITES: The sites in the Big Belt 

 Mountains of the Helena National Forest are the 

 only sites in Meagher County and include the 

 easternmost locality in the state. More detailed 

 population information on this species and its 

 location on a USGS 7.5' topographic map can be 

 found in Appendix 5. 



UNVERIFIED/UNDOCUMENTED REPORTS: None
