SPARGANIACEAE (Bur Reed Family) 



Sparganium eurycarpum Engelm. Giant Bur Reed 



Common in a marsh on the south edge of Ran- 

 dolph, and while there are many suitable situations 

 in the Allegheny valley, it was not seen elsewhere 

 in the region. 

 Sparganium americanum Nutt. Bur Reed 



In wet places in the Tunungwant valley and rarely 

 in the Allegheny valley. 



NAJADACEAE (Pondweed Family) 



Potamogeton epihydrus Raf. Pondweed 



Frequent in the Tunungwant creek, and perhaps 

 elsewhere in the quiet waters of the Allegheny river, 

 but the discharge of oily waste into the rivers of 

 this region has doubtless destroyed many of the 

 aquatics which may once have flourished here. 



ALISMACEAE (Water Plantain Family) 



Alisma Plantago-aquatica L. Water Plantain 



In muddy ditches and swamps, usually in clayey 

 or alluvial soil. Infrequent or rare and observed 

 only in lower Red House valley. Tunungwant valley 

 and along the Allegheny river. 

 Sagittaria latifolia Willd. Arrow-leaf, Arrow-head 

 Common in ditches, marshes and wet, usually al- 

 luvial soil along the Allegheny river and Tunungwant 

 creek. The very distinct var. obtusa (Muhl.) 

 Wiegand, occurs at Cold Spring and in the bayous of 

 the Tunungwant valley.
