80 THE CANADIAN NATURALIST. 



to this botanist for having been the first to observe the true 

 Woodsia alpina in Canada, a specimen of which in good fruiting 

 condition was exhibited. The plant found by Mr. Bell in 

 Gaspe, and referred by Dr. Lawson to W. glabella (see this Jour- 

 nal, 1864, page 288), and by Prof. Eaton to W. alpina (ditto, 

 page 4), appears to have been immature, and consequently diffi- 

 cult of determination. Dr. T. has also found the normal W. 

 glabella, and his station (the upper falls of the Riviere-du-Loup) 

 is the only thoroughly reliable Canadian one known to us for that 

 rare variety. A specimen of the Botrychium Lunaria of Swartz 

 of unusual size and in a perfect fruiting state, found by Dr. T. 

 at Riviere-du-Loup, was also shown. This fern proves to be 

 general throughout Canada; — its apparent rarity may be accounted 

 for by its inconspicuous mode of growth. 



Dr. Thomas says (in a letter to the Editor), " The flora of this 



interesting region (Riviere-du-Loup) is semi-arctic, the plants of 



Labrador and thence northward being found along with natives of 



central Canada. Among the Gentian aceae we have Pleurogyne 



rotata (a decidedly Labrador plant) and Gentiana acuta 



(Michaux), growing almost side by side with Halenia deflexa and 



other gentians of lower latitudes. * * * * Around Quebec, the 



hay-fields are white during summer with the flowers of the common 



ox-eye daisy (Leucanthemum vulgare, Lam.) ; but below Quebec 



it gradually becomes scarcer, until at L' Islet it stops, and is not 



seen below. The plant is introduced enough, as nearly all the 



hay-seed sown by the farmers is brought from Quebec. The 



corn-cockle (Agrostemma Githago, L., usually a too common 



weed) is extremely rare here. I have found no representations 



of the Goose-foot family (Chenopodiacese), which is remarkable. 



Our specimens of Saxifraga Aizoon are peculiar. The scape 



(or rather stem in this case) is decidedly leafy ; the leaves are 



alternate, and resemble those clustered at the root, which are 



thick, spatulate, and sessile, with cartilaginous margins, and 



are slightly smaller than the radicle leaves. Among the Scrop- 



hulariaceae, I collected Veronica Chammdrys, L., at Levis in 1859 



(where it is not common), with its leaves decidedly petioled, and 



not sessile as in the British plant; the petiole is not long — 



about J to r V of an inch, but still a petiole." W.
