A not inconsiderable element of western and southwestern plants is found in this 

 flora. Afany of these plants are typical of the rich lands of the Ohio and Mississippi 

 YaHeys. The following are plants of western and southwestern affinity which, so 

 far as can be determined, reach their eastern limit in the Cayuga Lake Basin or 

 extend bevond only to eastern New York:

A very interesting group of salt plants is found in the flora. These are nearly 

 all confined to the Ontario plain and adjacent parts of the lake valley. Some of these, 

 which occur about salt springs, are plainly influenced in distribution by the salt ; in 

 the case of other species less closely associated with such springs, the importance of 

 salt as a factor is less clear. The following salt plants are of interest : 



Eleocharis rostellata 



Ruppia maritima, var. longipes 

 Xajas marina 

 Zannichellia palustris 

 Triglochin maritima 

 Diplachne maritima 

 Phragmites communis 

 Puccinellia distans and var. tenuis 



(adventive) 

 Spartina Michauxiana 

 Hierochloe odorata, var. fragrans 

 Zizania aquatica 

 Panicum dichotomiftoriDn ? 



Scirpus nanus 



Scirpus campestris, var. paludosus 



/uncus Gcrardi 



Juncus compressus 



J uncus dichotomus, var. platyphyllus 



Chcnopodium rubrum 



Salicomia europaea (adventive) 



Spcrgularia alata 



Ranunculus Cymbalaria 



Hibiscus Moscheutos ? 



Sa>nolus floribundus ? 



Coastal Plain plants not directly influenced by salt constitute a small but distinct 

 element of the flora. In this connection the following may be mentioned : 



ll'oodwardia virginica 



Isoetes Engelmanni 



Potamogcton bitpleuroidcs (possibly 

 influenced by salt) 



Echinochloa Walteri (possibly influ- 

 enced by salt) 



Cyperus ferax ? 



Eleocharis quadrangulata 



Fimbristylis autumnalis 



Carex alata (possibly influenced bv 

 salt) 



Carex annectens (true) 



Carcx Howei 



Carex incompcrta 



Carex triceps, var. hirsuta 



Carex intumescens (true) ? 



Pcltandra virginica 



Juncus articulatus ? 



Listcra australis 



Myrica carolincnsis 



A Inns rugosa 



Polygonum pennsylvanicum (true) 



Polygonum robustius ? 



Drosera longifolia
