The aquatic plants of the lake are: Brasenia Schreberi (water 

 shield), Nymphoides aquaticum (floating heart), Nymphoides 

 lacunosum (small floating heart), Potamogeton diversifolius, 

 Potamogeton heterophyllus, Nymphaea advena (yellow pond 

 lily), Utricularia fibrosa (bladderwort), TJtricularia biflora 

 (bladderwort), and Mayaca fluviatilis. 



The Mayaca is new to South Carolina, not having been reported 

 before north of the Gulf States. It is a very delicate plant, 

 growing in considerable masses, entirely submerged in rather 

 shallow water.* The yellow pond lily has made an entrance in 

 the last few years. About four years ago I noticed one plant at 

 about the spot shown in Plate XL Now there are a dozen or more 

 colonies in that part of the lake. 



Water shield is now the most conspicuous aquatic plant of the 

 lake. Its small floating leaves coated on the underside with a 

 beautiful clear jelly cover the water in large areas near the edges. 

 A dense colony of it is shown in Plate XIII. 



Nymphoides aquaticum (Limnanthemum) , with large floating 

 leaves that look much like those of the water lily, is not abun- 

 dant; in fact, it appears to be much less so than it was several 

 years ago. A careful examination of more than a half mile of the 

 lake edge in June, 1912, revealed not more than a half dozen 

 plants. On the other hand, Nymphoides lacunosum, which has 

 appeared in the lake only in the last two or three years, is now 

 increasing rapidly. 



It is rather surprising that the water lily (Castalia odorata) 

 has not yet made an entrance into the lake. It is plentiful in Kil- 

 gore's Mill Pond, only about a mile away. 



Over a considerable area of the lake near the edge behind 

 Captain Cannon's Place the water is only a few inches deep, 

 forming a bog. The swamp had been cleared off here just before 

 the water was raised, but it is now covered with a rather dense 

 second-growth of the following plants: Taxodium distichum 

 (cypress), Salix nigra (black willow), Alnus rugosa (alder), 

 Cephalanthus occidentalis (buttonbush), Callicarpa americana 

 (French mulberry), Viburnum nudum ('possum haw), Nyssa 

 biflora (black gum), I tea virginica (Virginia willow), Boeh- 

 meria scabra, Typha latifolia (cat- tail), Saururus cernuus 

 (lizard's tail), and Peltandra virginica (moccasin corn). 



*There is much doubt as to distinctness of Mayaca -fluviatilis. In fact, I 

 am now convinced that it is nothing more than a submerged form of M. 

 AuUeti.
