1897.] The Swamps of Oswego County, N. Y. 1^1 



The species here which are exclusively moor plants are : Ledum 

 G'l'oenlandicum, Kalmia glauca, Andromeda i^olifolia, CJiamse- 

 daplme calyculata, Ghiogenes hispidula, Schollera oxy coccus and S. 

 Tnacrocarpa. Many others, especially species of Vaccinium, 

 live in the moor, but are not confined to them. 



Menyanthes trifoliata is a moor plant, and is not uncommon 

 in our region. 



The Lentibuliariacex contribute to this group Utricularia cor- 

 nuta, U. gibba, U. intermedia and U. resiqnnata, all of which are 

 rare plants and grow only in the newer portions. 



In the order Composite, but three species can lay claim to 

 being exclusively moor plants. These are Solidago ohioensis, 

 S. uliginosa and Aster junceus. 



THE FLORA OF THE WOODED BELT. 



The third zone of the whole swamp is still to be considered. 

 To attempt to enumerate the species as has been done in the 

 case of the bog and the lake would contribute little to our 

 picture of the swamp as a whole. The species are, for the 

 most part, the same as may be found upon the surrounding 

 uplands, especially in low- places. In fact, we may say that 

 just as the moor is steadily invading the lake, so the wooded 

 belt is invading the moor, and there is by no means the sharp 

 limitation to the outer edge of the wooded belt that there is to 

 the outer edge of the moor or of the lake. It is always a tree- 

 covered tract in the natural state, the size of the trees increas- 

 ing as one passes from the edge of the moor to the hard shore. 

 The trees which appear most frequently are Ulmus americana, 

 Acer saccharinum, Fraxinus nigra, Pinus strobus, TJiuya occiden- 

 talis, Larix laricina, Picea mariana and Betala lenta. Of these 

 the predominating species are the first three or four. Shrubs 

 are more abundant in the more open portions near the moor. 

 Lindera Benzoin, Ilex verticillata, lUcioides rnucronata and several 

 species of Vaccinium are the most prominent. The herbaceous 

 the wooded belt is not a very rich one. Caltha often covers flora 

 of the ground. The most prominent plants are the Osmundas, 

 which grow in rank profusion. Smilax hispidia, Arissema tri- 

 phyllum, Dalibarda repens, Trientalis americana, Medeola vir-
