though this moss is spoken of as being quite rare in the New 

 York region, it has turned up in many localities and is even 

 locally common. 



Liverworts were a conspicuous part of the swamp flora, 

 especially along the old corduroy road which leads to the old 

 iron furnace near Wawayanda lake. Bazzania trilobata was 

 everywhere. Ptilidium pulcherrimum was also common, its hair- 

 like leaves sometimes reddish brown, although usually green. Its 

 capsules were fully formed, ready to burst into fruit with the 

 coming of spring. The familiar Marchantia polymorpha of 

 botanical laboratories also flourished on the old road. Pellia 

 epiphylla, with a very thin thallus, inhabited several moist 

 banks at the edge of the ruts in the road. 



On the dry land, an island in the swamp yielded four species 

 of club-mosses growing but a few yards from each other. Lyco- 

 podium obscurum, L. complanatum, L. lucidulum and L. clava- 

 tum were identified by the group. The latter species grew in a 

 dense sward covering an area of several square rods.
