Vertical and horizontal distributions of roots and rhizomes were examined in five clones of galleta bisected near Cisco and Cedar City, Utah. Quantity of roots and rhizomes did not differ significantly between the two sites. Although high variability existed among clones at each site, both the root and rhizome systems at Cisco tended to be shallower than at Cedar City. This difference in distribution may result from soil and climatic differences at the two sites.
