NOTES ON THE FLOKA OP HAMILTON. 283 



extensive collection made hj the late Mrs. Smart, sister-in-law of 

 Judge Logie, and a most enthusiastic botanist, there are some — 

 probably a good many— plants not included in the lists which I lay 

 before you on the present occasion. If at some future period I should 

 have the time and the opportunity to examine her collection, I may 

 be able to increase considerably the list of Hamilton plants. 



On classifying the 812 species and varieties included in the two 

 lists, we find that there are 649 exogens, 121 endogens, 41 acrogens, 

 and 1 thallogen (Char a vulgaris, 'Jj.^. The disproportion between the 

 exogens and endogens would be less if the rushes, sedges and grasses 

 were thoroughly worked up. Thirty-eight of the plants have been 

 collected in parts of the Dominion remote from Hamilton, principally 

 near Cacouna and London; the remaining 774, either at Hamilton or 

 at various points in its neighbourhood. The most distant of these 

 points are: On the road to Toronto, Port Nelson; to the north, 

 Puslinch Lake; to the west, Gait and Paris; to the south, the Town- 

 ships of Binbrook and Glanford ; to the sou.th-east, the Welland peat- 

 bog; and to the east, the Niagara River. The most recent list of 

 Canadian plants, as far as I know, is that furnished for the Curtiss 

 Catalogue by Professor Macoun. Our list contains fifty-one species and 

 varieties not reported by Macoun. Several of these, I am informed, 

 were inadvertently omitted from the Catalogue; there may be room 

 for doubt as to the complete naturalization or accurate determination 

 of others; but after making all necessary deductions, a considerable 

 number wiU have been added to the list of Canadian plants. A very 

 large part — but not all — of these new plants are mentioned in Plub- 

 bert's Catalogue; but as I have no means of ascertaining to what 

 extent that Catalogue was conjectural, I do not feel bound to admit 

 that they have all been heretofore reported as Canadian. They have 

 not, at any rate, been recently reported, and there are at least a few 

 which do not occur at all in any previous list. The plants of the 

 occurrence of which we claim to be either the discoverers or the 

 re-discoverers, are distinguished by appropriate marks in the appended 

 lists, and specimens of some of the more interesting will be exhibited 

 at the conclusion of the paper. 



It will be noticed that a very large part of the plants reported — 



one-eighth, in fact — consists of naturalized plants. Some of those 



admitted into Judge Logie's list have, I do not doubt, been admitted 



on insufiicient evidence; but it is nevertheless the fact that a large
