PLANTS OF GEORGIAN BAY 203 



SESSIONAL PAPER No. 39b 



Beds of Chara — that most important breeding ground for minute algae, — 

 were seldom found. The following lists are far from being exhaustive even of 

 the small district investigated. 



Not expecting to undertake a study of the green plants, my supply of reference 

 authorities was far from complete, and necessitated much drawing and recording 

 of measurements for future reference. Only such specimens as lent themselves 

 by good condition, reasonable size, and characteristic marks, were determined. 

 Many non-fruiting forms of the higher algae were passed over unidentified. Sub- 

 sequent observation at a different season may add very considerably to every 

 group.
