Contains list of 255 native and introduced Iowa bog and marsh plants, with 
a considerable number from other states interpolated; also a bibliography, with 
many of the dates lacking. It is interesting to note that according to the list of 
plants there are no Ericaceae and no Sphagnum in the Iowa bogs. One of the 
causes of this state of affairs is probably the predominantly calcareous soil of 
Iowa.
