EUROPEAN HERBARIA. 19 
tenberg, and at the union of this university with that of Halle 
was transferred to the latter, where it remains under the care 
of Professor von Schlechtendal. It contains a large portion 
of the Carices described and figured in Schkuhr’s work, and 
is therefore interesting to the lovers of that large and difficult 
genus. The American specimens were mostly derived from 
Willdenow, who obtained the greater portion from Muhlen- 
berg. 
The royal Prussian herbarium is deposited at Schéneberg 
(a little village in the environs of Berlin), opposite the royal 
botanic garden, and in the garden of the Horticultural Soci- 
ety. It occupies a very convenient building erected for its 
reception, and is under the superintendence of Dr. Klotzsch, 
a very zealous and promising botanist. It comprises three 
separate herbaria, namely, the general herbarium, the herba- 
rium of Willdenow, and the Brazilian herbarium of Sello. 
The principal contributions of the plants of this country to 
the general herbarium, garden specimens excepted, consist of 
the collections of the late Mr. Beyrich, who died in western 
Arkansas, while accompanying Colonel Dodge’s dragoon expe- 
dition, and a collection of the plants of Missouri and Arkansas 
by Dr. Engelmann, now of St. Louis ; to which a fine selec- 
tion of North American plants, recently presented by Sir 
William Hooker, has been added. The botanical collections 
made by Chamisso, who accompanied Romanzoff in his voyage 
round the world, also enrich this herbarium; many are from 
the coast of Russian America and from California ; and they 
have mostly been published conjointly by the late Von 
Chamisso and Professor Schlechtendal in the “ Linnea” 
edited by the latter. 
The late Professor Willdenow enjoyed for many years the 
correspondence of Muhlenberg, from whom he received the 
greater part of his North American specimens, a considerable 
portion of which are authentic for the North American plants 
of his edition of the “‘Species Plantarum.” In addition to these 
we find in his herbarium many of Michaux’s plants commu- 
nicated by Desfontaines, several from the German collector 
Kinn, and perhaps all the American species described by
