ANNUAL REPORT OF THE BOTANICAL SECTION OF 

 THE OTTAWA FIELD-NATURALISTS' CLUB. 



(Read to the membeps of the Club Feb. iilh, 1902.) 



The Botanical Section reports that, as usual, the Club's excur- 

 sions were well attended by those interested in Botany. At all of 

 these excursions one or tnore of the botanical leaders were present 

 and assisted in the determination of the difficult species collected. 

 One of the rarest plants in this vicinity Petasites pahnata was 

 found by Miss Matthews near Britannia, on May 4th, the date of 

 the Club's excursion to that place, and the Hon. F. R. Latchford 

 found the same species near Mountain View about the same time. 



Several new species have been added to the local list during 

 the year. These include a number of Violets new to science : 

 Viola cardaminifoha, growing near Aylmer, Que., V. subviscosa, 

 from the same place, V. leucopetala, back of Rideau Hall, and 

 V. Fletcheri, from the woods near Creighton Lodge. The first 

 two were discovered by Dr. Fletcher, the last by Mr. J. M. 

 Macoun, and V. Fletcheri by Dr. Fletcher and Mr. Macoun when 

 working together. The violets of this vicinity are yet far from 

 being worked out, but, as descriptions of all the new species have 

 been published in The Ottawa Naturalist, even a beginner in 

 botany inay determine the common species. Other species added 

 to our flora are Thalictrum confine^ Fernald, collected by Prof. 

 Macoun near McKay's Lake, Agrimonia hirsuta and Triosteum 

 aurmitiacum. 



An unusually large number of botanical papers and notes 

 were published during the year. The most important of these 

 were : " Some New Canadian Gentians " by Dr. Theodor Holm, 

 'New Plants from Alberta" by Dr. Edw. L. Greene, "On the 

 Autumn Flowering of Various Wild Plants in 1900" by Mr. 

 Cephas Guillet, Part xiv. of "Contributions to Canadian Botany" 

 by Mr. J. M. Macoun, " Allies of Stellaria tnedia''' by Dr. Holm, 

 and descriptions of new Violets and Senecios by Dr. Greene. In 

 addition to these, short notes on local species were published frorh 

 time to time.
