134 THE PLANT LIFE OF MARYLAND 



Growing among the above species is an equally rich and diversi- 

 fied association of plants of subordinate stature. Few of these are 

 found in any considerable numbers in the pure stands of the Fresh 

 Marsh, but in the mixed stands they are abundant, and particularly 

 so in the inner portion of the marshes next the mainland, where 

 the stature of the dominant species is much less. These species are:

 J uncus acuminatus 

 Cyperus nuttallii 

 Iris versicolor 

 Oxypolis rigidus 

 Hypericum canadense 

 Willughbaea scandens 

 Galium triflorum 

 Triadenum virginicum 

 Polygonum sagiltatum 

 Polygonum arifolium

On all of the Fresh Marshes which extend from the river to the 

 upland the stature of the vegetation gradually decreases from about 

 six feet to a low turf only a few inches in height. The Salt Marsh 

 grasses Spartina patens and Distichlis spicata, occasionally extend
