The paper on the Liliales of Iowa is by T. J. Fitzpatrick^. 
The paper by L. H. Pammel lists the plants found from Mis- 
souri Valley, Turin, Sioux City and Hawarden but chiefly from 
Sioux City and Turin.^ 
The Iowa Geological Survey in the studies of local county 
geology has included reports on the forest conditions. Papers 
have been published by Shimek^® and Macbride^^. These papers 
usually included notes on the distribution of trees and their 
economic uses. In most cases definite localities are assigned to 
the species. At least the county is given. In those counties 
where the drainage is to the Missouri river as well as to the 
IMississippi one must assume that the Mississippian species oc- 
cur in the latter drainage area. 
A number of ecological papers also have been published. The 
most important paper is the one by Shimek^^, in which weather 
records and the study of the distribution of trees with reference 
to the wind and transpiration of water of plants are considered. 
In another paper Shimek^^ has made a study of the Flora of the 
Sioux Quartzite. The paper is interesting as showing the dis- 
tribution of trees on the Sioux quartzite. The species of trees 
found in this limited area do not differ from those found else- 
where in the region. The only trees found here are Fraxinus 
pennsylvanica var. lanceolata^ Acer Negundo, Tilia americana, 
JJlmus americana and Quercus macrocarpa. BooP^ made a com- 
parative study of the field and forest flora in Monona county. 
His study indicates a correlation between a prairie and a wooded 
area and that a gradual transition occurs.
