Catalogue of Canadian Plants. 101 



an excellent state of preservation, and represent in a very com- 

 plete manner the Flora of the Island of Montreal and its vicinity. 

 Under the care of the late Prof. Barnston, they were arranged 

 according to the classification of Gray ; the nomenclature was 

 modernized, and a catalogue partly prepared, to which it was 

 his intention to have added the results of his own researches, and 

 to have published the whole as a synopsis of the Flora of Montreal. 

 In its present form, the catalogue fails far short of this design ; 

 but it is hoped that its publication may nevertheless be regarded 

 as a useful contribution to Canadian Botany. The Island of 

 Montreal is geographically a very important station. Situated 

 between the parallels of 45° and 46° N. lat., at the confluence of 

 the St. Lawrence and the Ottawa, and presenting a great variety 

 of soil and elevation, it affords an epitome of the botanical condi- 

 tions of the middle region of Canada. The present collection 

 also derives additional interest from the circumstance, that it 

 affords many localities of species which have become locally 

 extinct, owing to the progress of cultivation and the extension of 

 the city. Lastly, the herbarium of the Colleg* being an anged 

 in such a manner as to be easily accessible, it is hoped that the 

 present catalogue may make it more useful to students of botany, 

 and that it may form a groundwork for a complete Flora of the 

 vicinity of Montreal. 



The names in the catalogue are those attached to the specimens 

 by Dr. Holmes. The more modern names, where any change 

 has occurred, are added with the initials J. B. The Grasses 

 and Carices of the collection, and a separate collection of Forest 

 Trees and Shrubs, still remain unarranged r and will, if possible, 

 be published in a supplementary list. — j. w. d.]
