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 Schoneberg 

 (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 " Linnaea " 

 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
