of the genus by its narrower leaves, less than 2 cm wide, that are not shiny on 

 the upper surface. These species do not overlap in their Montana distribution. 



C. GEOGRAPHICAL DISTRIBUTION 



1. GLOBAL RANGE: Quebec to Manitoba and eastern Montana, south 

 to Georgia, Texas, and Colorado. 



2. STATE DISTRIBUTION: Known only from the single historic 

 collection (1948) in Powder River County. 



3. STUDY AREA DISTRIBUTION: We were unable to relocate the 

 1948 population collection site in the course of this survey. The 

 original collection noted that there were only a "few plants." The vague 

 location infomiation is more likely to correspond with public rather 

 than with private land, yet it is possible that it was not collected on the 

 national forest. If the species had been collected on the Ashland 

 District, it may now be extirpated. An array of habitats were searched 

 by Lesica (1984) and in this study. The generally overgrown habitat 

 along the abandoned roadbed was not thoroughly searched, and should 

 be the focus of attention for any extended survey work. 



D. HABITAT: Habitat has been described as "rocky, open wooded hillsides, 

 prairie, roadsides" (Great Plains Flora Association 1986). Dry, open woods are 

 common in the vicinity of Sayle, where Montana's only known specimen was 

 collected. 



E. POPULATION BIOLOGY AND DEMOGRAPHY 



1. PHENOLOGY: The previous Montana collection was made in flower 

 on 17 June 1948. It is noted as having an indeterminate flowering from 

 April to August (Great Plains Flora Association 1 986), presumably 

 depending on climate. 



2. POPULATION SIZE AND CONDITION: Unknown. 



3. REPRODUCTIVE BIOLOGY 



a. TYPE OF REPRODUCTION: By seed. 



b. POLLINATION BIOLOGY: Unknown. 



c. SEED DISPERSAL AND BIOLOGY: Many members of this 

 genus have seeds which are dispersed by birds. The original
