'.Hi TIIK BOTANISTS OF I'll I I.A DKI.l'JI I A. 



Muhlenberg's valuable herbarium was bought l>y a 

 number of his friends fora little more than five hundred 

 dollars, and was presented to the American Philosophical 

 Society in Kehruary, L818. It was then in good condition, 

 hut has. unfortunately, l.ein^ allowed to suffer from neglect 

 until it is no longer of any value. 



Hi- -el-vices to science have been well recogni/ed by 

 botani-t-. A golden i-od was given by Torrey and (iray the 

 name ^<>!i<!"i/o MnJtlenbergii; a small willow was denomi- 

 nated by IJarratt Sail.,- Muhlenbergiana ; Grisebach named a 

 centau ry AY//////-,-"/ Muhlenbergii; Gray gave the name 1/W>- 

 I< nhergii to a species of reed or sedge, and Schrebcr the name 

 Mnlilfn/n'1-i/in to a -eiins of grasses. Two mosses of the 

 genera ritnxcuin and Funaria were named in honor of Muh- 

 lenberg bv Schwart/ ; two lichens of the genera Umbilicaria 

 and Gyrophora by Acharius ; and, by Elliott, a fungus of 

 the genus Dothidc<i. 



About half of the plant names, given by Mnhlenberg. 

 which are now recognized, belong to the plants of the 

 natural orders, Cyperacetc and Graminese, in the study of 

 which he was supported by Schreber. 



This review of Muhlenberg's botanical work would not 

 be complete without special reference to his scientific cor- 

 respondence, his personal intercourse with naturalists, and 

 degrees conferred. Among his foreign correspondents were

 Scln'ipf, Schreber. Sturm, \\'illdenow, William Alton, Batsch,
