{Read April 8, 1872.) 



The botanical notices given by Professor Lawson at the last 

 meeting of the Institute, reminded me that I have become acquaint- 

 ed with som.e facts respecting plants in difterent parts of the 

 Province which should be placed on record; and I now proceed 

 to offer notices of some of them to the members of the Institute. 



1. A Fern hitherto unknown in the Dominion. At the meeting 

 in question. Prof. Lawson announced the discovery of Lastrea 



fragrans at Cape Canso by Rev. E. H. Ball, and mentioned that 

 this is an interestin"; addition to the list of hitherto known Novii 

 Scotia ferns. The plant next to this in Gray's Manual of the 

 Botany of Northern U. S. (second edition), viz., Aspidiiim 

 aculeatum, I met with in 1870 in a wood on Marble Mountain. 

 Bras d'Or Lake, Cape Breton, about 600 feet above the lake, 

 I conclude that this fern has not as yet been mentioned as found in 

 the Dominion, from its not being referred to in Prof. Lawson's 

 Synopsis of Canadian Ferns and Filicoid Plants published in 

 Edin. New Phil. Journal 1864, or in any subsequent memoir I 

 have seen. Gray states {loc. cit.) that it is found on the moun- 

 tains of New Hampshire, Yerm.ont, N. New York and northward. 

 It is a common fern in Great Britain, where it is now called 

 Polystichum. aciileatum. The mounted specimen, one of the two 

 originally gathered by myself, I send to illustrate this note, is for 

 Subsequent presentation to the Provincial Museum as an addition 

 to the Herbarium of Nova Scotia Plants procured from me by the 

 Provincial Commissioners for the Paris Exposition of 1867. 



2. Anagallis arvensis, Linn. This pretty little plant, well 

 known in England as Poor Man's Weather Glass and Common 

 Pimpernel, is European, but naturalized in America. I found it 

 flowering in profusion near the Schoolhouse in Digby in 1868. I 

 have not seen it elsewhere in the Province.
