I : !ora of the Allegany State Park Region 187 



The herbaceous species listed here are those which were 

 seen by traversing the stream from near Stony brook 

 (figure 30) to a point about a mile below Headquarters 

 (Frecks) (figure 31), and do not include many of the 

 common woodland species occurring back a little distance 

 from the stream. The abundance of some of the stream- 

 side species is undoubtedly determined by the open char- 

 acter of certain stretches of the stream rather than by any 

 marked influence of the stream itself. This is true of 

 some of the species of Goldenrod, Aster, Sedges and 

 Grasses. On the other hand, there are stretches of the 

 stream where the unbroken forest ends abruptly beside 

 the stream. The species which seem to be largely de- 

 termined as regards abundance by the influence of the 

 stream are printed in heavy type.
