 association of hill prairie plants is much stressed by sylvan and 

 thicket elements, and hence verges into the thicket vegetation of 

 the uplands. With these may be associated certain isolated 

 patches, as for instance one in the thicket east of the water- 

 works dam-, consisting of Desmanthus Illinoensis, Schranckia 

 uncinata, Rosa humilis, R. setigera, and Eriophorum lineatum, 

 the only station of this plant on high ground. The following
