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 

 Phaenogamous 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 108, 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 Leguminosae, Rosacea;, Compositse, 

 Labiatae, Liliacese, Cyperaceae 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 Cupuliferae. Ranunculaceae 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 Illecebraceas (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
