FusiCLADiUM ON Cherry. — It is feared, judging from the indica- 

 tions o[ last season, that the disease known as "Aj^pleScab" or "spot" 

 {Fiisicladiiun dendritiann, Fckl.), which has thus far principally affected 

 the Apple and Pear, is likely also to prove dangerous to the Cherry. A 

 single variety only was affected in the Experimental Farm orchard this 

 year, but so severely as to cause the loss of the entire crop. GrunerGlas(?) 

 the variety attacked, is one of Prof. Budd's importations from Eastern 

 Europe. Two trees of this variety were growing vigorously and were 

 heavily laden with fruit which was nearly mature when the disease was 

 first noticed. Specimens were sent to Mr. D. G. Fairchild, Assistant 

 Vegetable Pathologist, at Washington, D. C, who identified the disease 

 as the true Fusicladium of the Apple. The foliage was also attacked 

 but less severely than the fruit — J. Craig, Ottawa. 



A Fern New to Canada. — An addition to our Canadian Ferns 

 in the shape of Asplenijim ruta-mui'atia, L., has been made this year 

 by Dr. P. J. Scott, of Southampton, Ont., who discovered it growing 

 plentifully on the rocks of Flower Pot Island, about four miles from 

 Tobermorey, a small place near Cape Houd in the north of Bruce Co., 

 Ont. The specimens sent me for determination are very fine and typical. 

 The nearest before known stations for this interesting species were in 

 Vermont and Michigan, U. S. — T. J. W. Burgess, Montreal. 



Introduced plants. — The three North Western \)\2,x\\.^ Helianthus 

 rigidus, Lepachys coluninaris^ and Grindelia sqiiarrosa, which were 

 reported last season by the Botanical Section as having been found 

 near Eddy's old mill-yards at Birchton, were again noted in the same 

 locality a few weeks ago. It does not seem probable that the two first 

 named will prosper in their new home, as no vigorous specimens were 

 met with ; but Grijidelia squartosa has evidently struck a very congenial 

 habitat. The number of plants of this species has greatly multiplied 

 since last year while its territory is very considerably enlarged. Many 

 stout thrifty specimens were noticed even on a well-beaten road. An 

 interesting feature of this plant is its profuse resinous-viscid coating. 



Several fine specimens of the Walking leaf fern {Comptosorus 

 rhizophyllus) were gathered at old Chelsea on Oct 15th. The past 

 season seems to have been very favourable to its growth as it was found
