FLORA OF BOULDER, COLORADO

The aspen, however, is not confined to the bogs, but forms 

 groves in slight depressions throughout the mountains, and oc- 

 curs on Green Mountain not much, if any, above 6,000 feet. 

 The aspen occurs in the drier portions of the bogs along with 

 other uliginose plants. The bog vegetation is very rich in
