Many of the common species have a general Appalachian distribution, but it has 

 proved difficult to distinguish accurately between those so distributed and those of more 

 central or southern range. Some of the rarer plants which show an Appalachian dis- 

 tribution are: 



Elymus canadensis (true) 

 Glyccria melicaria ? 

 Dantlwnia compressa 

 Car ex radiata (true) 

 Carex aestivalis 



Diccntra eximia ? 

 Ribes rotundifolium 

 Amelancliier intermedia 

 Rhododendron maximun 

 Kalmia latifolia 



INTERESTING BOTANICAL REGIONS 



In the territory covered by any flora there are naturally certain regions of special 

 interest. Information about such localities in the Cayuga Lakp Basin may be desired 

 by students as an aid in their own local explorations. Some of the more important, 

 of these regions are discussed in the following pages, beginning with those at the 

 northern end of the basin. 



Duck Lake region. — In the region of Duck Lake there is a series of extensive 

 bogs, some calcareous and some acid, lying in an area of moderately light, generally 

 calcareous, glacial deposit, which deposit forms the low uplands between the swamps. 

 Several small lakes are included here. As the region lies on the Ontario plain and 

 not far from the salt springs of Montezuma, there is some evidence of the effect 

 of salt upon the vegetation. In the region lie Duck Lake, Mud Pond, Crusoe Lake, 

 Duck Lake swamps, Miller Bog, Featherbed Bog, Mud Pond bogs, and Butler tama- 

 rack swamp. The more interesting and unusual plants are :
