282 NOTES ON THE FLORA OF HAMILTON. 



to assert that an incomplete list is better than none at all, and that if 

 air the observers in Canada "vrho have made more or less complete 

 collections in the localities in which they reside would summon 

 courage to contribute the results of their observations to a common 

 fund, our knowledge of the distribution of plants in Canada would be 

 materially increased, and the study of our local floras greatly stimu-, 

 iated. Our knowledge of the distribution of Canadian plants is indeed 

 so limited, and geographical botany is so important a subject in its 

 relations on the one hand to climate, and on the other to the vexed 

 question of the origin of species, that one may be excused for feeling, 

 and pardoned for endeavouring to excite, an interest in it. 



There are in Judge Logie's collection, exclusive of duplicates, 676 

 Canadian plants, of which 597 are indigenous and 79 naturalized. 

 How carefully he pressed and how neatly he mounted his specimens 

 may be judged from those which I now exhibit to you; and I believe 

 that he was equally painstaking in his determinations. Of course, in 

 ao large a collection, there must be some errors in naming, and in the 

 list which I have made, I have ventured in one or two instances to 

 express my disagreement with his determinations; but, though I have 

 not had time to examine carefully many of the plants, my impression 

 is that the proportion of errors is very small. Of a number of the 

 most common plants, with the occurrence of which Judge Logie 

 must have been perfectly familiar, the collection contains no speci- 

 mens. To remedy this deficiency, I have prepared a supplementary 

 list of plants, which I am able from my own observations to add to 

 his list. The majority of the additional plants are of common occur- 

 rence, but som© are rare ; and one or two, of which specimens will be 

 exhibited at the conclusion of this paper, are, it is believed, reported 

 as Canadian for the first time. The additional list contains 136' 

 plants, of which 113 are indigenous and 23 naturalized. There are, 

 therefore, on the two lists, 710 indigenous and 102 naturalized, in all 

 812 plants. I have marked with a B those plants in Judge Logie's 

 collection which I have noticed in the vicinity of Hamilton, and 

 independently determined. There are 442 so marked; and, accord- 

 ingly, of the 812 plants, the occurrence of 442 is vouched for by 

 Judge Logie and myself, while that of 234 depends on the correctness 

 of Judge Logie's, that of 136 on the correctness of my determinations. 

 The total of 812 does not include all the phaenogams and vascular 

 cryptogams that have been observed to occur at Hamilton. In the
