578. Anaphalis margaritacea (L.) Benth. and Hook. Pearly Everlasting. 

 (Antennaria morparitacea Hook.) 



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

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

 work. The patch of Mentha rotiindifolia was noted too late to 

 press, so the identification is doubtful. 



SUMMARY. 



The area included within a line along the crest of the hills suiTounding 

 Eagle Lake presents for study a remarkable variety of conditions and 

 ecological I'egions, as (1) upland forest, with native trees and shrubs; (2) 

 cleared and abandoned upland with the flora that has subsequently taken 

 possession; (3) creek, valleys and gullies, with their peculiar soil and flora; 

 (4) railroad and introduced flora; (5) lowland forest; (6) lake plain; (7) 

 tamarack swamp; (8) ponds, temporary and permanent, and quaking bogs 

 and bayous; (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 others a thick 

 carjjet of dried leaves. The soil is sandy, and many of the herbs of 

 xerophytic habit. Fungi are abundant. 



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

 mulberry and so on. Many mat plants are present, and there is a tendency 

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

 Among these plants are five-finger and dewberry. Just at the base of the 

 slopes Fimhristplis is abundant. 



Creek valleys and gullies have a peculiar fiora on Their slopes, and alsa 

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

 extensions of the lake plain. Among many characteristic plants are skunk 

 cabbage, Conocephalus, Blephilia, and so on. 



The railroad has an interesting introduced flora of wild lupine. Salsola 

 kali, squirrel-tail grass, white amaranth, and many other species. 



The Lowland Forest, a dense, tangly jungle with 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.
