BOTANICAL INFORMATION. 371 



The royal Bavarian herbarium at Munich, is chiefly valu- 

 able for its Brazilian plants, with which it has been enriched 

 by the laborious and learned IMartius. The North Ameri- 

 can botanist, will, however, be interested in the herbarium 

 of Schreber, which is here preserved, and comprises the 

 authentic specimens described or figured in his work on the 

 grasses, the American specimens mostly communicated by 

 Muhlenberg. The Gramine<x oi this and the general herl>a- 

 rium, have been revised by Nees von Esenbeck, and still 

 later, by Trinius. It was here that the latter, who for many 

 years had devoted himself to the exclusive study of this tribe 

 of plants, and had nearly finished the examination of the 

 chief herbaria of the continent, preparatory to the publication 

 of a new Agrostographia, was suddenly struck with a pa- 

 ralysis, which has probably brought his scientific labours to 

 a close. 



The Imperial herbarium of Vienna, under the superin- 

 tendence of the accomplished Endlicher, assisted by Dr 

 Fenzl, is rapidh' becoming one of the most valuable and ex- 

 tensive collections in Europe. The various herbaria of 

 which it is composed, have recently been incorporated into 

 one, which is prepared nearly after the English method. It 

 however possesses few North American plants, except a col- 

 lection made by Enslin, (a collector sent to this country by 

 Prince Lichtenstein, from whom Pursh obtained many spe- 

 cimens from the Southern States,) and some recent contri- 

 butions by Hooker, &c. There is also an imperfect set of 

 the plants collected by Haenke, (a portion of which are from 

 Oregon and California,) so far as they are yet published in 

 the Reliquiae Hcenkeanae of Presl, in whose custody, as curator 

 of the Bohemian museum at Prague, the original collection 

 remains. 



The herbarium of the late Prof Sprengei still remains in 

 the possession of his son, Dr Anthony Sprengel, at Halle, 

 but is offered for sale. It comprises many North American 

 plants, communicated by Muhlenberg and Torrey. The 

 herbarium of Schkuhr was bequeathed to the university of
