THE FLORA OF THE MOOR. 
There is no group of plants more interesting from the point 
of view of their geographical distribution than the one which 
constitutes the moor flora. Allusion has already been made 
to the probable post-glacial history of the flora; and attention 
has also been called to its relation to the Alpine flora of New 
York State. The general fact that the two floras approach 
each other toward the north until we find them closely asso- 
ciated in Arctic regions, is pretty conclusive evidence of closer 
association in post-glacial times. But their limited distribu- 
tion and their relation to our Alpine flora is no more interest- 
ing than their distribution in the moor itself. Some of the 
plants are restricted to the newer portions of the bog; others 
are only found in the older portions. Those of the newer por- 
tion are, in general, the invading plants; those of the older 
portion sometimes persist in the wooded belt. In the older 
portions of the bogs there sometimes appear upland plants. A 
general survey of the species may here be made. 
The Juncaginacee are all marsh plants. In our region they 
are, so far as I know, mainly confined to the newer portion of 
the sphagnous moors. Triglochin maritima occurs at Mud 
Lake, Oswego town, “ Paradise,” So. Mexico, Granny’s Orchard, 
Palermo, and other places. According to the Manual (Gray’s) 
it occurs at the seashore and in saline places across the Conti- 
nent. Mud Lake is by no means a saline place. T. palustris 
has not been seen, so far as I know, in Oswego County, but oc- 
curs at Junius, Seneca County, in the same basin, also upon 
the “ boggy borders of Onondaga Lake; at Salina, and north- 
ward beyond Liverpool” (Paine, l. c., p. 81). Scheuchzeria oc- 
curs in the newer portions of all our sphagnous moors. 
There are but few grasses: Phragmites, Muhlenbergia racemosa, 
Panicularia canadensis and Calamagrostis canadensis are fre- 
quently found in the moors, but are not confined to them. 
On the other hand the Cyperaceæ is one of the best repre- 
sented orders. Here, and here almost exclusively, the species 
of woolgrass (Eriophorum) grow. Oneof the most effective 
bog-making plants in this region is Carex filiformis, the root- 
stocks of which form a very strong warp into which other
