The one botanical work with which his name is commonly 
associated, is his Catalogue of North American Plants, in which 
a number of his species were first made known. It was printed 
in 1813, by William Hamilton. A posthumous paper treating 
of the grasses and sedges, and containing descriptions of a num- 
ber of new plants was issued by his son two years after his death. 
Some of his species were also published in Willdenow’s Species 
Plantarum, and some in Elliott’s Botany of South Carolina and 
Georgia. He was also greatly interested in the medicinal and 
economic side of botany, and contributed much that was of value 
to the several medical botanies published at this time. 
Recently while preparing the manuscript for the second 
edition of my Catalogue of North American Plants, I took occa- 
sion to note the plants to which Muhlenberg’s name is attached 
as author. Eighty of these were listed, but there are perhaps a 
few more. His specialty seems to have been grasses and sedges, 
his name standing after 16 species of the former, and 20 of the 
latter. He also described two ferns. 
The importance of Lancaster county as a botanical field is 
evident when we reflect that a goodly number of the types of 
these species must have been obtained in the vicinity of the city 
itself. 
One of his species is Ranunculus fascicularis, and the type 
station is probably on the Conestoga at What Glen, or rather 
the remains of that place. I collected fine specimens there last 
spring, and it is the only station known to me. Another little- 
known species of Ranunculus, only recently rescued from the 
mass of synonymy where so many good species have been rele- 
gated by botanists who managed to obtain a monopoly of taxo- 
nomic work without the corresponding broad knowledge only 
to be obtained by extensive field work, is R. ¢trzfoliatus, also 
found in rich wooded ground along the Conestoga. <Aradzis 
laevigata occurs in similar situations. 
_ Another denizen of rich wooded slopes, and one of the earl- . 
iest bloomers, is Deztarza lacinzata.
