sliould have been found so plentifully this year, while of M. ophioglos^ 

 soides, which in previous years had been obtained in large numbers, 

 only one specimen was found. This habit of appearing in large numbers 

 and then disappearing is peculiar to some families especially Orchids 

 and Aquatics. Good collections were also made of Asjndium cristatum 

 var. Clinlonianum. In the Rideau Canal Mr. Fletcher found Lemna 

 minor flowering profusely, the first date on which it was noticed was the 

 5th Jxily. This has not previously been recorded as having been found 

 in flower in Canada. At the same time the form of Potamogeton 

 Vaseyi with emei'sed leaves was found in fruit ; some good specimens 

 were obtained, but a large proportion was found to be infested by a 

 parasitic fungus. A few poor s[)ecimens taken from dried plants were 

 sent to Professor Farlow, of Havvard University, who replied concern- 

 ing it : " The specimens are very interesting. The fungus is something 

 " which I have never seen before, and which, as far as T can ascertain, is 

 " as yet undescribed. It is probable that it belongs to the Ustilaginece 

 " but it is possible that it belongs to a new genus." The study of these 

 parasitic fungi is at the best very difficult, and can only be done satis- 

 factorily from fresh specimens and in larger quantities than were sent ta 

 Professor Farlow. A peculiar form of Potamogeton 2nisilb(s with small 

 emersed leaves was noticed, this form the Rev. T. Morong pronounces 

 as very similar to the Sicilian variety of P. pimUiis called 2^(inormi- 

 tanus Biv. Three or four expeditions were made to the Mer Bleue with 

 good results, large collections being made of Eriophorum vaginatum, 

 Carex pauciflora, Carex limosa and Carex exilis. The last named has 

 not before been noticed in Canada, it is a species common along the base- 

 of the White Mountains and very probably it will be found between 

 this locality and its native habitat. 



In conclusion, Ave appeal to the members generally to make more 

 notes for the benefit of the committee. The earliest date that leaves 

 were noticed on certain trees, or the first and last appearance of any of 

 our wild flowers, may appear of little value, yet, when added to the 

 observations of others, may prove a very useful contribution to science.
