Fig. 26. Station XXXI, habitat 3, Frenchman Island. View looking 
southeast, Dunham Island in the distance. To the left is 
habitat 2, the Typha association. The middle foreground is 
habitat 3, which includes a mass of vegitation, Pontederia, 
Nymphaea, and Castalia. A heavy growth of Carex tri- 
chocarpa borders the shore, back of which lies the sloping, 
stony beach which is bare of vegetation. This is shown in 
the foreground. In the distance, on the right of the picture, 
may be seen several pure Dianthera associations. 
Fig. 27. Station XXXII, north side Long Island, view looking south- 
east. The shore is lined with Carex trichocarpa. The more 
open water where Professor Hankinson is standing is filled 
with Scirpus occidentalis and S. americanus with a iew 
Dianthera. The dark patch of vegetation in the background 
is almost wholly Dianthera.
