PARRY’S CATALOG OF IOWA PLANTS OF 1848 
WINIFRED ELLSWORTH 
In 1852, David Dale Owen, United States Geologist, published 
his “Report of a Geological Survey of Wisconsin, Iowa, and Min- 
nesota,” and included in the volume as Article V a systematic 
catalog of plants of the Northwest by C. C. Parry. Parry’s list 
bears the misleading title “Systematic Catalogue of Plants of 
Wisconsin and Minnesota, made in Connection with the Geological 
Survey of the Northwest, during the season of 1848.” But in 
the second paragraph of Mr. Parry’s explanatory introduction to 
his list he says, “I have also incorporated some personal obser- 
vations made during a previous season in the State of Iowa, being 
properly comprised within the District of the Northwest, and 
enabling me to present a more complete view of the botanical 
features of the region than could otherwise be done during a single 
season’s operations.” His Iowa collection was made, therefore, 
during a season previous to 1848, and thus precedes Bessey’s list 
of 1870 by more than twenty-two years. The Iowa plants are 
scattered in the list among the Wisconsin and Minnesota plants 
and it seems worth while to cull them out into the separate list 
given below. In most cases Mr. Parry has indicated the time of 
collection, the locality and its soil condition. He acknowledges 
his indebtedness to Dr. John Torrey for the authentication of his 
doubtful specimens.
