NEW AND RARE PLANTS—LAWSON. 71 
Returning to Canning in the evening, we started next morn- 
ing, and botanized the gorge through which Dr. HAMILTON’s road 
winds up tothe summit of the North Mountain. Here also there 
was a magnificent growth of ferns along the banks of the rill, 
composed principally of Lastrea marginalis, L. dilatata (spinu- 
losa), Polystichwm acrostichoides, P. Brawnit, Struthiopteris ger- 
manica, not very plentiful, Polypodiwm Phegopteris and Dry- 
opteris, with fine patches of var. erectwm of the latter, Athyriwm 
Fili« femina, Polypodium vulgare, &e. Here, with var. McKuyit 
of Cystopteris fragilis, we found a single tuft of a form with broad 
leafy approximate pinnee like the ordinary European state of the 
plant. It was at this place that Mr. JAcK found, some years ago, 
a tuft of Woodsia obtusu, a species which, although not so very 
rare in the United States, was not previously ascertained to be 
Canadian. It has indeed been regarded as a Canadian fern, but 
in my Synopsis, published some time ago, it was pointed out that 
there was then no evidence. 
On the following day we visited the “ Look Out,” a favourite 
place of resort for visitors, from which there is a magnificent 
view of the Cornwallis Valley. Here we obtained a supply of 
Woodsia Ilvensis and also a very few specimens of Aspleniwm 
Trichomanes, which was very scarce, but was subsequently found 
on a cliff in a gorge to the westward of Canning, by Colone] 
CoLLINGwoop. Near the same place Master CoLLINGWoop found 
Veronica Americana. It is necessary to mention, in the interest 
of visitors to the Look Out, that there is, along the base of the 
eliff and amongst the stony debris, a great profusion of the Poison 
Ivy (Rhus Toxicodendron), which causes, on many persons, by 
simple contact, a disagreeable and even dangerous eruption on 
the skin. 
It is remarkable that, with exception of a few local species, 
nearly all the ferns of Nova Scotia are to be found on the North 
Mountain.
