The herbarium at Kew has recently acquired two very valuable 
private collections, Dr. Burchell’s South African and South Ameri- 
can collection, by gift from his sister, and the herbarium of Orchids 
of the late Dr. Lindley, by purchase. The latter contains upwards 
of 3,000 species, in pertect condition, fastened upon cartridge-

and G. Bentham, F.L.8., &., is published. It contains the 
Leguminosze, Rosaceze, Saxifragaceee, Haloragaceze, Rhizophoree,

volume of 1,000 pages, 
SwEpEN.—The Academy of Sciences at Stockholm is about to 
publish a fac-simile of a very interesting relic—a phtoto-lithogra- 
phic copy of the first edition of the ‘Systema Nature’ of Linneus, 
a folio of about fourteen leaves. Though very thin, it contains the 
groundwork of nearly all that the great Naturalist has accom- 
plished. 
America.—A catalogue of plants found in Oneida County, New 
York State, has been recently published by the authorities. This 
catalogue embraces the whole of the central part of the State of 
New York, and its author, Mr. John A. Paine, jun., has expended a 
great deal of labour in its preparation. ighty-one native plants 
(species and varieties) are enumerated at the close, which are addi- 
tions to the Flora and Catalogue of the plants of this State by Dr. 
Torrey. ‘Twenty-five new plants are enumerated as naturalized. 
Professor Asa Gray says, “ For a public document, this catalogue is 
well-printed, and as a hasty essay by an unpractised hand, it is 
creditable to its author, although there are many points which would 
not bear close criticism.” * 
At a recent meeting of the American Philosophical Society in 
Philadelphia, it was stated that the native plants of Pennsylvania 
were being rapidly displaced by the European flora. European
