Summit Marsh and Spencer Lake. — The region of Summit Marsh and Spencer 

 Lake lies on the valley floor on the watershed between the Cayuga Lake Basin and 

 the Susquehanna Valley. It was through this valley, in part, that the glacial waters 

 flowed southward from the melting ice in the Ontario Basin. It is interesting, 

 therefore, to note that the flora of these marshes shows a somewhat greater affinity 

 with that of the present Ontario plain than with that of the adjoining hills. Some 

 of the interesting plants of this region are: 



Sparganium minimum

High hills south of Ithaca. — The hilltops of the plateau region furnish a number 

 of plants which are rare or absent in other parts of the Cayuga Lake Basin. Some 

 of these have a northern, some a southern, affinity. The larger_ part of the soil is 

 noncalcareous. The following plants may be mentioned as inhabiting this region: 



Lycopodium annotinum, and var. acri- Panicum tsugctorum 



folium 

 Lycopodium clax'atum 

 Lycopodium tristachyum 

 Abies balsamca 

 Deschampsia flcxuosa
