IRONDEQUOIT RAY. 



The shores of Irondequoit bay and the slopes of the depression 

 which continues several miles south of the water are high and steep 

 bluffs of clays or sandy silts. Through this deposit the tributary 

 streams have cut deep, narrow gullies. Isolated masses of the deposit, 

 as "sugar loaves" and butte-like mounds, give a very picturesque 

 character to the upper or southern part of the gorge. 



The flora of the shores of the bay is not in any degree distinctive, 

 but is remarkable rather for the great variety of species of plants 

 found here, some of which are mentioned as follows. The trees are 

 principally oak and chestnut, with a few pignut hickory, birch, poplar, 

 hemlock, witch hazel, and occasional specimens of white and pitch 

 pine. Desmodiums, Lespedezas and Lupins are plentiful. Aquilegia 

 Canadensis, Baptisia tinctoria, Viburnum acerifolium, Hieracium venosum, 

 H. paniculatum, H. scabrum, Vaccineum stamineum, V. Pennsylranicum, 

 Pyrola rolundi/'o/ia, P. elliplica, Gaultheria procumbens, Rhododendron 

 nudiflorum, Gerardia flava, G. quercifolia, G. pedicularia and Cypripe- 

 dium pubescens are common. Epigcea repens was formerly abundant, 

 but is now scarce. Anemone cy/iudrica, Tephrosia Virginiana, Castil- 

 leia cocci ne a, and Chamcelirium Caro/intanum, though scarce, are more 

 frequently found here than elsewhere. Arenaria stricta, Hibncus 

 Moschcutos, Poterium Canadense, Potentilla paluslns, Salix Candida and 

 Polygonum Muhlenbergii are rare. Campanula roiunditolia var. arctica, 

 Gentiana puberula, Fcstuca lenella, and Cyperus filiculmis have not been 

 found elsewhere in our district. Of Pterospora Andromedea a single 

 specimen has been found. 



The extremities of the bay are filled with beds of flags. All the 

 forms of Typha are present, T. latifolia var. don gat a being the most 

 plentiful. Extensive beds of Chara exist. Elodea, Myriophyllum 

 spicatum and various species of Potamogeion are abundant. Wolffia
