366 BOTANICAL INFORMATION. 



lection in the world for Lahiatce, and is perhaps nearly unri- 

 valled for LegvminoscB^ Sci'ophularinea;, and the other tribes 

 to which he has devoted especial attention : it is also particu- 

 larly full and authentic in European plants. Prof. Lindley's 

 herbarium, which is very complete in every department, is 

 wholly unrivalled in Orchidaceous plants. The genus-covers 

 are made of strong and smooth hardware paper, the names 

 being written on a slip of white paper pasted on the lower 

 corner. This is an excellent plan, as covers of white paper 

 in the herbarium of an active botanist, are apt to be soiled 

 by frequent use. The paper employed by Dr Lindley is 

 181 inches in length, and IH inches wide, which, as he him- 

 self remarked, is rather larger than is necessary, and much 

 too expensive for general use. 



The herbarium of Sir Wm. J. Hooker, at Glasgow, is not 

 only the largest and most valuable collection in the world, in 

 the possession of a private individual; but it also comprises 

 tiie richest collection of North American plants in Europe. 

 Here we find nearly complete sets of the plants collected in 

 the Arctic voyages of discovery, the overland journeys of 

 Franklin to the Polar Sea, the collections of Drummond and 

 Douglas in the Rocky Mountains, Oregon, and California^ 

 as well as those of Prof. Scouler, Mr Tolmie, Dr Gardner, 

 and numerous officers of the Hudson's Bay Company, from_ 

 almost every part of the vast territory embraced in their 

 operations, from one side of the continent to the other. By 

 an active and prolonged correspondence with nearly all the 

 botanists and lovers of plants in the United States and Cana- 

 da, as well as by the collection of travellers, this herbarium 

 is rendered unusually rich in the botany of this country ; while 

 Drummond's Texan collections, and many contributions from 

 Mr Nuttall and others, very fully represent the Flora of our 

 southern and western confines. That these valuable materials 

 have not been buried, nor suffered to accumulate to no pur- 

 pose or advantage to science, the pages of the Flora Boreali- 

 Americana, the Botanical Magazine^ the Botanical Miscellanys 

 the Journal of BtAany, the Iconcs Plantarnm, and other works
