[PENHALLOW] A REVIEW OF CANADIAN BOTANY 21 



collections. Through the kind assistance of Dr. Warming of Copen- 

 hagen, Prof. Blytt of Christiania, and Dr. Kind berg of Linkoping, a very 

 nearly complete series representing the flora of Northern Europe has been 

 obtained. 



One of the most important features of the herbarium is a series of 

 plants collected by the earlier explorers, and representative of nearly all 

 the plants described in Hooker's Flora Boreali Americana. This very 

 important addition was made through the courtesy of the Director of the 

 Bi-itish Museum of Natural History. The herbarium, as now constituted, 

 embraces *70,000 sheets. 



McGiLL University. 



The foundation of the McGill College Herbarium was laid in the 

 gift of the collections of Dr. A. F. Holmes, the first professor of botany 

 in the Medical Faculty. Subsequently, under the direction of Sir Wil- 

 liam Dawson, a number of additions were made, chiefly as derived from 

 students' collections. In 18Y6 Prof. Macoun deposited his centennial 

 collection with the College, and it has lately been incorporated with the 

 University herbarium, to which it was donated by the Geological Sur- 

 vey. In 1883 the material thus brought together was properly mounted 

 and systematically arranged, and since that date extensive additions 

 have been made both by gift and by purchase. These additions are 

 representative of Australasia, India, Ja2:)an, South Africa, South America, 

 and Northern Europe. The collection now embraces about 30,000 speci- 

 mens. 



The economic collection includes an important group of plant pro- 

 ducts chiefly from India, comprising dyes, foods and textiles, and speci- 

 mens illustrating nearly all the Canadian timber trees, as well as many of 

 those of the United States. 



In addition there is a special collection embracing all known species 

 of North American trees and shrubs, prepared for special research work, 

 and represented by (a) hand specimens, (6) microscopical preparations 

 and (c) sections prepared for the microscope, but kept in bulk. These 

 preparations constitute the type material employed by Prof. Penhallow 

 in the prosecution of special researches connected with a classification of 

 woody plants. 



Laval University. 



The herbarium of Laval University at Quebec is the oldest in Canada, 

 having been formed b}' the late Abb6 Brunet in 1860, during his occupa- 

 tion of the chair of botany. " The Canadian plants Avhich the herbarium 

 now contains were gathered for the most part by himself, and are the
