THE AMERICAN BOTANIST. 
SO complete as it might be had I the time for more extend- 
ed search, still a few notes concerning my trips to one bog 
in particular may not be without interest to readers of 
The Botanist. 
I usually intend to visit the place during the first week 
in July for then is to be found that most beautiful of our 
native orchids Cypripedium spectahile ; some ^^ears in 
abundance and again only a few scattered plants. Alwa^'s 
at the same time I find the common pogonia {Pogonia 
ophioglossoidcs) as well as the grass pink {Calopogon 
pulchellus). As yet I have failed to find the arethusa (A. 
bulhosa) although another bog, a few miles to the north, 
has a few plants. This bog would appear to be an ideal 
spot for the Habenarias, but only once have I found one 
of them here. That species was Habenaria tridentata. 
Of course many more are to be expected in such places and 
probabl3^ further search will be rewarded by new finds. 
The swamp saxifrage {Saxifraga Pennsylvanica) is a 
conspicuous plant and the water arum (Calla palustris) is 
abundant in spots. That beautiful member of the gentian 
family the buckbean {Menyanthes trifoliata) and the 
common pitcher plant (Sarracenia purpurea) are i)resent 
as they alwa3"S are in such places. 
The heath family furnishes a large number of species 
particularly of the low shrubs, among them being the 
marsh andromeda {Andromeda poUfolia), the privet 
andromeda (.4. ligustrina), the leather leaf {Cassandra 
calyculata), the sheep laurel {Kalmia angustifolia) and 
the swamp blue-berry {Vaccinium corymbosum). The 
small cranberry {Vaccinium oxycoccus) is present as is 
also the snowberry {Chiogenes serpy Hi folia). 
The white plumes of the cotton grass {Eriophorum 
polystachyon) dot the open places in this bog, while many 
other sedges particularly carices abound. In the pools of 
open water I found a green plant which bothered me to 
analyze for some time but which I finally found to be the 
water star wort {Callitriche heterophylla). 
' The surface of the bog is partially covered with a
