An Ecological Studv of Buckeye Lake. 43 



area are some Castalia plants. There are also some in sheltered 

 coves on the east side of the island. 



Associated with the Castalia and always present in appreci- 

 able numbers are several species of Potamogeton. In fact the 

 semi-aquatic plants which have gained a foothold are mostly Pota- 

 mogeton lonchites, P. natans, P. pectinatus, P. pusillus and P. 

 foliosus, of these P. lonchites is the most abundant. The best 

 development of the association is on the northwest and north 

 sides where the water is shallow and vdiere the irregularity of 

 the shore line affords many sheltered coves. The association is 

 spreading from the north shore of the lake toward the island 

 and if not too much disturbed by the fluctuations in the water 

 level, will no doubt soon fill this narrow and shallow water 

 area. The south and southeast sides of the island extend ab- 

 ruptly into deeper water, and are also exposed to the full sweep 

 of the wind. Plere the fixed aquatic association is almost want- 

 ing along the margin. A few Potamogeton plants and Algae 

 are in evidence close against the bank sheltered by the ex- 

 posed Alder roots and Hibiscus stems. 



There are small scattered Peltandra virginica societies in 

 small, shallow depressions in the shore at the water's edge, all 

 thru the thicket border and also in such depressions in the open 

 bog. They are also a prominent part of the vegetation of the 

 small islands skirting the shore of the bog. One such, north of 

 the b'og, is merely a rather dense growth of Peltandra virginica 

 and Pontederia cordata growing on a slightly elevated mass of 

 peat. 



Nymphaea advena, another fixed aquatic tho quite abundant 

 in other parts of the lake, is wanting near the margin of the 

 bog; this makes the presence of the plant in a single small pool 

 well towards the center of the bog-meadow all the more striking.

The shallow coves on the northern, northeastern and east- 

 ern margins and all the larger lagoons on the east side have an 

 abundance of dead timber chiefly Rhus, Alnus and Acer trunks.
