traveled downward from the summit, and quoted their opinion 

 that L. selago is a xerophytic form of L. lucidulum. In regard 

 to this, Mr. J. B. Flett writes that if the one intergrades with the 

 other, it is doubtless due to elevation or cold, and not to 

 xerophytic conditions. As to the plant's habitat in the northwest, 

 he says : "I have never seen L. selago growing in a really dry place, 

 I have studied this form in the field from Washington through 

 British Columbia into the islands of southwestern Alaska and on 

 the Aleutian Islands, also on the tundra between Cape Nome and 

 Cape York. No one familiar with this tundra region would ever 

 assert that there are any xerotic forms on it." 



SCOLOPENDRIUM FROM CANADA. 



By Homer D. House. 



At least four stations for the Harts-tongue fern are known 

 in the vicinity of Owen Sound in northwestern Ontario. Speci- 

 mens from these localities are rare in herbaria, and the writer is 

 fortunate in receiving specimens from near Collingwood, a 

 station twenty-three miles east of Owen Sound. This station 

 was first authentically reported by Mr. Osier and described by 

 Mr. Maxon in "Fernwort Papers" in 1900. These specimens 

 were collected by Dr. W. A. Bastedo and he describes the place 

 where they were collected as being five or six miles from Col- 

 lingwood. The plants were growing in a shady, though rather 

 open wood, along the course of a small stream. The altitude is 

 given as 1635 feet above sea-level. The plants at the time 

 of collection, July 17th, 1903, were nearly all young and even 

 the mature fronds are but five to eight inches in length, though 

 all of them are very broad for their length. Dr. Bastedo further 

 notes that in the recesses of the cliff, snow was still abundant 

 at that date. Polystichum Lonchitis and Dryopteris Filix-mas 

 were abundant and Asplenium Trichomanes and Cryptogramma 

 Stelleri were common upon the cliffs. This station is undoubta- 

 bly one of those described by Mr. Maxon in the neighborhood of 

 Collingwood. However, a careful search of this entire region is 

 very much to be desired, as it is probable that the fern has a 

 more general distribution in this region than is known at present.
