Kilgore's Mill Pond. 



This is a small body of water, much older than Prestwood's 

 Lake, that lies in the low sand hills about one mile northeast from 

 Hartsville. A study of the vegetation and its surroundings 

 resulted in the collection of a considerable number of plants not 

 seen around Prestwood's Lake. Nymphoides lacunosum and 

 Nymphoides aquaticum are abundant, and submerged in the 

 stream just below the mill race was Scirpus subterminalis, not 

 before reported south of Xew Jersey (but I find a collection of it 

 in the N. Y. Bot. Garden from Mississippi).! 



On the west side of the pond is a flat marsh, inundated gener- 

 ally with several inches of water, which is covered almost all over 

 with a pure growth of Eleocharis melanocarpa. In deeper spots 

 this is replaced by Eleocharis quadrangulata. On the edges of this 

 marsh grew abundantly Rynchospora glomerata and Fuirena 

 squamosa. J uncus repens grew in dense patches in the shallow 

 water while Rynchospora comiculata and Juncus scirpoides were 

 scattered on the margins. Utricularia juncea also grew spar- 

 ingly here, but on the other side of the pond it was so plentiful 

 in the shallow water as to give a marked yellow color to the 

 margin. In the same situation on the east side was the little 

 Eleocharis Torreyana, partly submerged and mixed with Mayaca 

 Aubleti and some Nymphoides lacunosum. Behind these was a 

 zone containing clumps of the large, handsome Xyris fimbriata 

 mixed with the smaller Xyris elata and with Ascyrum hyperi- 

 coides % Proserpinaca pectinata, Schlerolepis uniflora and some 

 large "hat pins" (Eriocaulon decangulare) . Back of this zone 

 is a dense growth of the large grass Panicum scabriusculum, with 

 some of the attractive tall sedge Scirpus Eriophorum. With these 

 were a few small scattered individuals of Alnus rugosa, Nyssa 

 biflora and Acer carolinianum. In about this situation were 

 found a number of specimens of the greenish white orchid Habe- 

 naria clavellata, one of the rarest of our plants. 



This zone passes beyond into a flat moist bay of poor soil cov-
