W 



of this view, there being seemingly no difference in soil or climate 

 sufficient to account for it. The forest of this region differs mark- 

 edly from that of any other part of Canada, for while the trees, else- 

 where the chief components, occur, the bulk of it is made up, in ad- 

 dition to those I have already named, of chestnut, black walnut, 

 tulip-tree, buttonwood, white-heart and broom hickories, butternut, 

 chestnut oak, scarlet oak, and black oak. 



Fiom Prof. Macoun's Catalogue I have prepared two lists ; one 

 giving the names, localities and authorities for the occurrence of the 

 Thoenogamous species peculiar (so far as known) to the Lake Erie 

 region ; the other those very rarely noted as occurring elsewhere in 

 Canadian territory. The former includes io8, the latter 26 species. 

 These combined lists give us 134 plants, out of a total of 2955, 

 restricted, or almost restricted, to this district, that is, a twenty- 

 second part of all the plants known to occur over our vast territory, 

 from the Atlantic to the Pacific, are confined to it, and I have no 

 doubt that quite a number of additional ones will be brought to light 

 when the country is fully worked up. 



113 out of the 737 genera known in Canada, or rather more 

 than one-seventh, are represented in the same region, while very 

 nearly one-half the orders, or 54 out of 118, occur. The orders 

 most largely represented in these two lists, as one might naturally 

 expect from their size, are the Leguminosse, Rosacece, Compositae, 

 Labiatae, Liliaceae, Cj'peraceae and Graminese, but, if we go by the 

 proportion of the species to those forming the order in Canada as a 

 whole, the ones best represented are Caryophyllaceae, Umbelliferae, 

 Juglandaceae and Cupuliferse. Ranunculacese and especially Erica- 

 ceae, judged by the same standard are, by all odds, the lowest in the 

 scale of numbers. Four of our Canadian orders find their sole repre- 

 sentatives in the Lake Erie District, viz : Magnoliaceae (Magnolia 

 Family) by Magnolia acuminata and Liriodendron Tulipifera, 

 Anonaceae (Custard-apple Family) by Asimina triloba, Bignoniaceae 

 (Bignonia Family) by Tecoma radicans, and Hemodoraceae (Blood- 

 root Family) by Aletris farinosa ; while of the two representatives in 

 Canada of the lUecebraceae (Knawel Family) one, Anychia dichotoma, 

 occurs here, the other. Paronychia sessiliflora, in the Northwest 

 Territory. 



A very curious fact that cannot but strike one forcibly in 

 glancing over these lists is the large number of species, noted by the
