cm long. These characteristics are 

 consistent with tongue-tip pollination 

 involving noctuid moths (Grant and Grant 

 1965) . 



SEED DISPERSAL AND BIOLOGY: Each flower 

 produces a capsule with three locules, and 

 generally 1 (2-4) seeds per locule. The 

 seeds do not become mucilaginous when 

 moistened as in some other genera of the 

 Phlox Family. Thus, there appear to be no 

 special adaptations for seed dispersal and 

 nothing is known of the seed biology. 



POPULATION ECOLOGY 



1. BIOLOGICAL INTERACTIONS 



COMPETITION: No studies have been done on 

 competitive interactions, either 

 intraspecif ic or interspecific. However, the 

 frequent occurrence of Phlox kelseyi var. 

 missoulensis in open, unshaded areas suggests 

 that it is not very tolerant of competition 

 from other plants, especially for light, and 

 would not do well in communities with 

 overtopping vegetation. 



LAND OWNERSHIP 



Seven of the ten occurrences of Phlox kelseyi var. 

 missoulensis in Montana are on land managed by the 

 U.S. Forest Service. The other three occurrences 

 are on privately owned land. Specific information 

 for each occurrence is given below and exact 

 locations are listed in Section IV, pp. 12-22.
