The quiet waters of the streams tributary to the eastern end of 

 the lake abound in such species as Azolla Caroliniana VVilld., 

 Heterantha ditbia (Jacq.) MacM., Wolffia Columbiana Karst, 

 Polygonum .emersum (Michx.) Britton, Nymphaea advena Soland., 

 N. Kalmiana (Michx.) Sims, Sparganinm simplex Huds., -S". 

 Americanum Nutt., Comarum pahistre L., Menyaiithcs trifoliata 

 L., Utriadaria vulgaris L., Saururus cernuus L. and several 

 species of Potamogeton. In the shallow waters of the lake occur 

 some of the same species found in the streams with the following, 

 Limnanthemum lacunosum (Vent.) Griseb., Sagittaria graminca 

 Michx., Naias flexilis (Willd.) Rost. & Schmidt, Equisetum 

 fluviatile L., Scirpus fluviatilis (Torr.) A. Gray and Roripa Ameri- 

 cana (A. Gray) Britton. 



The occasional sandy beaches of the southern shore present 

 about the same floral characters as those of the eastern shore. 

 At Lewis Point is also found Equisetum littorale Kuehl., E. hyemale 

 intermedium A. A. Eaton, and a plantain which seems referable 

 to Plantago halophila Bicknell. In low marshy places Teucrium 

 boreale Bicknell is abundant, and Selaginella apus (L.) Spring, 

 thrives everywhere. Dryopteris simidata Davenp. is reported from 

 the southern shore by Dr. Haberer. Two ferns might be men- 

 tioned here which were observed in unusual habitats, Botry- 

 chium obliquum Oneidense Gilbert, along the edge of high-water 

 mark, and Ophioglossum vidgatum L., considerably below that 

 mark, both rather scarce, however. The flora of the northern 

 shore and of the western end of the lake is not so well known to 

 the writer as that of the eastern portion of the lake. However, 

 where sandy beaches are present the flora is without doubt similar 

 to that of the eastern shore. 



Space cannot be taken to enumerate all of the species peculiar 

 to this region or interesting to the collector, but enough have 

 been noted to give a general idea of the character of the flora and 

 to show that in some respects it is of a decidedly local nature. 

 There are no strictly maritime species present, as are found at 

 Onondaga Lake. At the latter place several salt springs produce 

 semi-maritime conditions. Onondaga Lake, however, lacks the 

 extensive sandy beaches and sand barrens of Oneida Lake, which
