PRETZ: FLORA OF LEHIGH COUNTY, PENNSYLVANIA 53 
have botanized within the county, and several visits by members 
of the Philadelphia Botanical Club have been made. The fol- 
lowing residents of the county are likewise interested in our flora: 
Rev. Dr. J. A. Bauman, Messrs. M.S. Hartung and H. D. Bailey, 
and Rev. W. N. Kopenhaver. 
In the following list, unless otherwise indicated, in every case 
where a station has been named, its exact distance is given in a 
carefully approximated direction from some name onthe Topo- 
graphical Maps of the U. S. Geological Survey, which cover all 
but a small portion of the county. The actual bog, streamlet, 
etc., may not appear on these maps but exists nevertheless and 
the above method is intended to standardize these citations and 
make the use of local terms subordinate. Distance from the City 
of Allentown has been given from the Center Square.
