 (Antennaria murgdritacea Hook.) 



Scattered, in dry places. Out of flower during tlie season at 

 Eagle Lake, but noted, and found and determined in subsequent 

 work. The patch of Mnithii rot iindi folia was noted too late to 

 press, so the identification is doubtful. 



SUMMARY. 



The area included within a line along the crest of the hills suri-oundiug 

 Eagle Lake presents for study a reniarkaltle variety of conditions and 

 ecological regions, as (1) upland forest, Avith native trees and shrubs; (2) 

 cleared and abandoned upland with the flora that has subsequently taken 

 possession: Ci) creek, valleys and gullies, with their peculiar soil and flora; 

 (4) railroad and introduced flora: (f)) lowland foi'est; (♦)) lake plain; (7) 

 tamarack swamp; (8) ponds, temi)orai-y and permanent, and quaking bogs 

 and l)ayous: (9) ice ridge; (10) beach; (11) the lake, with several zones of 

 plants. 



The upland forest is much like forests in general throughout Northern 

 Indiana. In some places there is underbrush and herbs, in otliers a thick 

 carpet of dried leaves. The soil is sandy, aiul many of tlie herbs of 

 xerophytic habit. Fungi are abundant. 



The cleared land is covered witli sassafras, sumac, scrub oaks, Russian 

 mullx'rry and so on. ^Nlany mat plants are present, and there is a tendency 

 of various species of herbs to occupy exclusively the ground they grow on. 

 Among tlu'se plants are five-finger and dewberry. Just at tlie liase of the 

 slopes Fiiii'irififi/li.'^ is abmidant. 



Creek valleys and gullies have a i)ecidiar flora on their slopes, and also 

 in the rich alluvial soil of their bottoms. In many cases they resemble 

 extensions of the lake plain. Amcmg many characteristic plants are skuulc 

 cabbage, ('oiiorcphriliist. BJephilut. and so on. 



The railroad has an interesting introduced flora of wild lupine i^alsola 

 kali. s(iuirrel-tail grass, white amaranth, and many other species. 



The Lowland Forest, a dense, tangly jungle Avith a rich sandy loam 

 soil, contains numerous and interesting species. Quaking asp. elm and 

 sycamore are representative trees. The herbs are various, rank, shade and 

 moisture loving species.
