 REPORT OF THE BOTANICAL BRANCH, 1893. 



To the Council of the Ottawa Field- Naturalists' Club : 



The Leaders have much pleasure in reporting that a considerable 

 amount of good work has been done during the past season, several 

 new plants not previously reported from this locality having been dis- 

 covered by members of the Club at the Excursions and sub-excursions. 

 Good work has also been done at excursions made by one or two 

 members who have visited localities too far distant to be reached by the 

 whole section. Excursions were made to various points on the Gatineau 

 Valley Ry. by Messrs. R. B. Whyte and John Craig and Prof. Macoun. 

 Mr. Scott and Mr. Fletcher made several visits to the Mer Bleue and 

 Cassleman, and made interesting collections. Mr. R. H. Cowley makes 

 the following interesting report : " The colony of the introduced North 

 Western plant Grindelia squarrosa first observed some years ago at 

 the old Eddy mill-site in Nepean, is still in a prosperous condition. It 

 is multiplying rapidly and seems to have found a congenial habitat." 

 During the third week of August Mr. Cowley paid a brief visit to 

 Clarendon, in Pontiac County, and visited a few of the neighboring 

 islands in the Chats Lake, on all of which he found many specimens of 

 Lobelia ICalmii, Potentilla fruticosa, Pycnanthemum lanceolatum, and 

 Aster ptarmicoides in full flower. The last three were first found by Mr. 

 R. H. Cowley and Mr. R. B. Whyte on the Chats Island in 1891. 



The following plants may be mentioned among the more interest- 

 ing of the season's collections : 



Ranunculus sceleratus, L. This addition to the Flora Ottaiva- 

 ensis was made by Mr. R. B. Whyte. The specimen was found at 

 Borthwick's Springs on July 8th. 



Myriophyllum alterni folium, DC. Specimens of this rare 

 water weed were found by Mr. Wm. Scott in Brigham's Creek, Hull, 

 Que. They were in fine condition in September and were growing in 

 about a foot of water The only other recorded locality for this plant 

 is " Lake Memphremagog, July, 1866." (Macoun's Cat. V, p. 322:) 



Lonicera oerulea, L. The two bushes of this species which 

 grow near the gas spring in the Mer Bleue were visited this year and 

 good specimens obtained.
