372 BOTANICAL INFORMATION. 



Wittemberg, and at the union of this university with that of 

 Halle, was transferred to the latter, where it remains under 

 the care of Prof. 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 Muhlenberg. 



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 Klotzscb, 

 a very zealous and promising botanist. It comprises three 

 separate herbaria, viz., the general herbarium, the herbarium 

 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 ihe 

 collections of the late Mr Beyrich, who died in Western 

 Arkansas while accompanying colonel Dodge's dragoon ex- 

 pedition, and a collection of the plants of Missouri and 

 Arkansas, by Dr Engelmann, now of St Louis; to which a 

 fine selection 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 Cali- 

 fornia ; and they have mostly been published conjointly by 

 the late Von Chamisso and Prof. Schlechtendal in the 

 Linncca^ edited by the latter. 



Tlie 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,
